Bacteria
A prime example of hidden bacteria from kizzle:

Is it the off center circle taking up almost all of the dish?
Quote:
Kizzle said: It's the very light film covering the "uncolonized" area. I don't know how many dishes like that slipped by before I finally noticed it but I started to wonder why the mycelium was suddenly stalling instead of colonizing the whole plate 
Quote:
blindingleaf said: bacteria on WKZ culture. both plates started off looking rhizo/normal, but as they aged, several sprouts popped up, and the second plate, u can see the edges of the growth are bubbling up in response to bacteria. these are both from same clone, same day.
 
another one (slight bacteria/hidden something), matazapec, MS, unfruited

compare to a very clean Penis envy culture

White molds
This is a random white contamination I got I wanted to share, showing how similar some white molds can be. This right here is why you NEED to be thorough. The contamination is circled.

This is another one, except the circled in part is healthy mycelium:

Since these were transfers that went wrong, I know for a fact everything outside of the spots I transfered to are contaminations (also I've been keeping a close eye on them since I noticed the white growths).
Exactly 3 weeks later
First one:
 Notice how much the growth has grown out.. 
Second one:
The clean growth is black, but what's interesting is the mycelium colonized through the stuff highlighted in red. HOWEVER. The white growths and shit in the red shows how unorganized it is. This is something you SHOULD NEVER trust. Mycelium colonizing contams doesn't mean it vanquished it. The contamination is still there, and it's still dormant.
It's also interesting to note.. they both smelled extremely mushroomy.. If I was to use my nose, I'd think they were clean. Even though I know they're not. This is why I really don't like advising people to sniff shit (unless your spawning or birthing, then sniffing every jar is recommended ). Your eyes are 10x better at spotting crap during colonization though.

blindingleaf said: here is a good pic of a hidden contam. its verticillium fungicola and its a white mold. it was a nuisance to me for many months. found out it was riding on the myc, but would not show itself until a week+ after full colonization of plate. top left is vert only top right is vert + cube mycelium after plate consolidated for a week or two bottom plate is healthy cube mycelium after 2 week consolidation.

note the intertwined plate has a 3d fuzz look to it. starts in the middle, and works its way out

Quote:
bodhisatta said:

its hard to tell from pictures because of shitty white balance settings but though the cobweb on this plate looks white it was pretty off white. the cube mycelium is in the middle it's the brighter white and it was completely overcame.


cobweb is a bit of a bad word since there's cobweb disease which is a disease of the fruit body crop. and then what shroomery calls cobweb mold which can be many species of molds with a similar morphology. but may have very different spores for instance
Unknowns and mixture between the 2

From the back with a light through it

Honestly I'm not sure exactly what it is but it only showed up after about 15 days post transfer and is in every single transfer from the mother plate.
This is likely the reason I was throwing all my stuff away
This is a great example to show how sometimes it can get so intertwined you'd need to be to get it undone.
If you look carefully, the areas that are clean are always organized. It's the main reason I go for rizmorphic organized areas
Here are some examples of organized clean plates:
For this one I would stay clear of the stuff on the bottom one at 6 o'clock.

Turned into:

blindingleaf said: a very clean Penis envy culture

Some species/varieties don't have rizmorphs. Like panaeolus species, but I still aspire for organization:

It's just crazy how close and hidden they all look, and makes me wonder how many contaminations I've had slip under the radar. The majority of these contams will most likely still have fruits if they don't turn green during spawning or fruiting. You'd just have a crappie pinset/BE. Or in the case of bl, a massive vert infestation on your fruits. Since I've become thorough, I RARELY see any contaminations. This right here is why I never say that I don't need to improve my techniques, or that I'm 100% clean. I'm not, and I'm constantly working on my sterile procedures.

Thanks man, also I'm getting my hands on petris in bulk. You're absolutely right. That is what makes petris superior. I was actually just thinking about this the other day, and this is kind of the icing on the cake, so to speak.

I've learned my lesson the hard way when it comes to hidden contams. The white molds looking so similar seemed OK to me until I ended up with a sneaky contaminated jar and g2ging it. I'm glad you guys post things like this. It really is very helpful. I'll definitely invest in some petris here soon.

I still have a culture that has a mold intertwined so tight that you can't tell its there. Grow it out and try to fruit it and you can.
It's fucking spooky when it happens to you, you become paranoid that every piece of mycelium looks suspect.

@synthetic, thanks and I hope it helps when you're working with agar. If you get sleeves of petris, they're pre-sterilized. They don't need to get pc'd. You can use glass petris too, but I think disposable petris are just easier, stack nicer, and nicer to look through. Plus they don't need a pc cycle.
@jbaby thanks 
@madd haha honestly, if you look carefully, the areas that are clean are always organized. It's the main reason I go for rizmorphic organized areas.. However as you can see in kizzles first picture, clean and organized looking doesn't mean you're in the clear. So yeah being paranoid and thorough on agar is how you get success 
Also do you have pics of said intertwined contamination? That'd be really cool to see

Aspergillus! I've had a couple transfers that looked kinda fluffy/tomentose and pure white, that turned out to be aspergillus. Glad you got some pics of it kizzle

How do I bump? god I love contams. Well it's a love hate relationship. I love it when you work your way around or through them. I'm just rambling. Cheddar cheese anyone?
In all seriousness, I hope this helps someone who's having major contamination issues realize that maybe they need to take a step back, read my improve your sterile techniques link in my signature, and try it all over again. I've had to go back to spores on agar before. Won't be the last time either

nice thread. I was recently made aware that I have been probably transfering mold from one plate to the other just because I assumed that the myc of that variety was puffier. How many times can you transfer from plate to plate to keep stuff going ? I have no slants for cultures but I have a lot of petris

You can transfer weekly for well over 6 months. They say to g2g only 3 times max due to the amount you're expanding the mycelium, and rough housing it due to shaking it and breaking it up. It'll bring on senescence way quicker. With agar you can go well over 20 times. If you pour your dishes a bit thick, you can let it colonize and store it in the fridge in petris for a few months.
Generally I transfer once or twice to ensure it's clean. Also every variety can be fuzzy/tomentose. My ape and aa+ are extremely fuzzy looking. However there's contaminations that are fuzzy looking too . That's why rizmorphic and organized is the best thing to go for. Especially when starting out.

QFT. not saying tomentose can't perform, but as far as safety goes, i also go for rhizomorphic.

until you find out the different uses each of those contams have. Like the black mold aspergillus Niger. It can actually be eaten and used for enzymes. Penicillium is used to make penicillin and cheese. Certain yeasts can make different things with just sugar water. Like alcohol. I've heard of people isolating yeast in the air and using it to brew some insane wines.
There's lots of other things out there just waiting to be discovered through the processing of molds.
That's actually some interesting stuff. I didn't know contams could be used for anything productive tbh. Learning something everyday on this site

Haha me too learning every day! Yeah molds are essential for us. There's actually lots of medicines utilizing them. Penicillin is just 1 of the most famous ones. Without penicillin I'd imagine the medical world would be a completely different place. If you're at all like me, and apparently the guys I respect on this thread , you'll start to find yourself reading up on contams, and actually liking them :O.
Also it seems to really increase your success rates if you understood where the contam came from, and how you got it. You can work around it EASILY if you know what the source is. I know I'm not the only successful grower who probably has their grow room filled with mold spores. Only place I'm really anal about is my sab

You need to identify it. Probably under the scope. You can't just take a random yeast and start making alcohol tho if you got a bunch of different samples, there's a chance you could accidentally come across it

Yep, two of my best friends are into beer brewing and they have wild yeast on agar right now, so they would be a lot of help! One of the yeasts is supposedly from a dog's ear.

@renegade you'll get it down contams are also part of this hobby. When you get them you should stress where it came from. Don't go overboard and bleach the room every time. In fact I've never bleached a chamber let alone a whole room 
@devon420 it's most likely normal. Mycelium behaves differently with amount of nutrients, and types of nutrients. As long as you are confident in the agar work, you really shouldn't have anything to worry about:)

bacteria on WKZ culture. both plates started off looking rhizo/normal, but as they aged, several sprouts popped up, and the second plate, u can see the edges of the growth are bubbling up in response to bacteria. these are both from same clone, same day.
 
another one (slight bacteria/hidden something), matazapec, MS, unfruited

compare to a very clean Penis envy culture

that is so true. it happens to us all. sometimes in long streaks, sometimes short ones. sometimes just here and there. we are growing mushrooms indoors, in make shift clean rooms. mold loves to hide in small crevices. it happens to the best of us, and no one should be ashamed of it. that kind of pride will be a persons downfall and should be avoided at all costs. lets be real. its ok, it doesn't make you a bad person, or a bad grower. usually, the opposite is true, and it will make you a better one if ur observant enough about the situation.

that is so true. it happens to us all. sometimes in long streaks, sometimes short ones. sometimes just here and there. we are growing mushrooms indoors, in make shift clean rooms. mold loves to hide in small crevices. it happens to the best of us, and no one should be ashamed of it. that kind of pride will be a persons downfall and should be avoided at all costs. lets be real. its ok, it doesn't make you a bad person, or a bad grower. usually, the opposite is true, and it will make you a better one if ur observant enough about the situation.
aint that the truth well said seems like whenever I get a contam it's always an epic 20 jar fail lol but eh it is what it is

lol yea, i hear that man. truth be told, even g2g can fail us like that. agar plates are key. assuming technique is on point, the OG plate will always tell the whole story in those cases.

Man I went for like a year and a half not able to grow a fucking thing past first flush, and only 50% of what I tried even made it that far.
But I'll be goddamned if I'm not an expert on contamination now though. Keep at it and learn as you go.

and a quick update. This contam.. I've been keeping it around out of laziness really. Too lazy to throw it out 
Quote:
This is a random white contamination I got I wanted to share, showing how similar some white molds can be. This right here is why you NEED to be thorough. The contamination is circled.

This is another one, except the circled in part is healthy mycelium:

Since these were transfers that went wrong, I know for a fact everything outside of the spots I transfered to are contaminations (also I've been keeping a close eye on them since I noticed the white growths).
Well here they are now! Exactly 3 weeks later!
First one:
 Notice how much the growth has grown out.. 
Second one:
The clean growth is black, but what's interesting is the mycelium colonized through the stuff highlighted in red. HOWEVER. The white growths and shit in the red shows how unorganized it is. This is something you SHOULD NEVER trust. Mycelium colonizing contams doesn't mean it vanquished it. The contamination is still there, and it's still dormant.
It's also interesting to note.. they both smelled extremely mushroomy.. If I was to use my nose, I'd think they were clean. Even though I know they're not. This is why I really don't like advising people to sniff shit (unless your spawning or birthing, then sniffing every jar is recommended ). Your eyes are 10x better at spotting crap during colonization though.

I know this is a somewhat old thread but i was wondering if its okay to only use half of the petris in the sleeve. I know they come with some type of gas in it that keeps it sterile but once i open the sleeve is it okay to use half and then reuse them later?

There's no sterilizing gas. They're sterilized with radiation. You just have to keep them sterile by closing off the sleeve they're before you take them out of the SAB/FH.

Anyone got more pics of hidden/meshed molds?
Ever since I suspected a few plates of having them every piece of mycelium seems suspect now.
This thread is a goldmine by the way, shame it is not full of pics. Hopefully I won't have resurrected an old thread for nothing :P.

Too bad. Been noticing some suspect mycelium in some of my cultures. Not knowing for sure is a nuisance, guess I will have to test them out by fruiting one by one.

Make sure they're uniform and organized. It can take many, many transfers sometimes. If they're not organized and uniform, they're not clean in my books. I've never had a culture I couldn't clean up. Even plates covered in bacteria before any cube germination I've saved with just transfers (no antibacterial agents used). I've seen lots tell others it is garbage when it's pure bacteria, but it isn't the case if you enjoy cleaning cultures lol. You get a huge sense of fulfillment when it works

That's the problem though, they look organised but strange, like having trouble growing over the agar surface or going from rhizo to wispy after a xfer when the recipe is the same.
I'm stuck changing my decision every 15 mins I spend staring down at them.

Like the one below. Some parts it's organised and beautiful yet all around it is all this strange growth. Strange thing is, the sector I took that transfer from was totally rhizo with no cottony growth at all.

There are others which I took transfers from nice rhizomorphic growth but they have a hard time staying above the surface and growth is all strange.

I tried to take clear pics of the growth under the surface the other day, this is the best I could come up with.

Would you say this culture has a slight hidden bacterial issue, Mad? It was grown out with slow pin formation, and results weren't anything to write home about.

Looks off. Theres a lot of "aerial" growths. I would try to transfer until it is smooth.

So you're concerned because it grows under the surface? Like to the bottom of the dish under the agar? If you use food colouring, you'll see the myc break it down.
The first has many sectors because it still has lots of genetics in it. Keep transferring from the leading edge until you get to it looking like this:

If you're talking about the thin film around it, that is just mycelium.
The last 3 pics, the first 2 need to grow out more before making much of a call on it, but so far they look alright to me, the last one has leading edges perfect for transfers. It can take lots of transfers before they look uniform and organized.

Yeah, the stuff under the surface is what I meant.
I have never really looked at them with this much detail before so that's why I'm not entirely sure about it but it does seem awfully suspicious to me. I have never seen mycelium do this before. I know mycelium does colonize agar completely but never really done so like this before.
Guess I will know for sure once I try and fruit some of these.

Sometimes that just happens, especially when transferring to a different agar mix. Keep transferring until you get a monoculture though. It's the best way to help ensure it's pure.

Does mycelium climbing the walls of a colonized plate definitely mean it's bacterial, or could it be because some of the agar liquid is actually on the sides of the plate (or in my case glad mini rounds)?

Myc will climb the walls regardless. Oyster myc will bust out of a plate.

Mycelium normally does colonize the sides if you let it. The extent to which it seems to vary but it's not related to bacteria. You should try not let it colonize to that point though since it can grow into a contaminated part of the petri.

Thanks for the re-assurance. I am still isolating it, I'll use the plates I took transfers from on grains to see what they do as well.
Pretty sure I used a shitload of spores in that inoculation, this is taking forever . God help me if I isolated and kept all the strains, I would have well over a hundred, at least. I am trying to choose around 20ish of the most good looking and rhizomorphic ones, that should give me a good isolate I reckon.

I need to start doing proper transfers, just got 100 dishes so ill start in the morning. If anybodys interested in yeasts for brewing you can collect the yeasts from the air with an open container over a few weeks the traditional way. I have some mead made this way thats got some dried cherries soaking in it meow. Also should you buy some beer you enjoy, you can collect it's yeast from the bottom of the bottles if you poured em right. Just did this the other day drom magic hats ticket to rye.

Mycogone hard to spot before it matures. Damn have spend hundreds of petri. Can you still isolate once it hits?

So I'm not the only one.. XD
Yea, it's a motherfucker. It basically pretends to be healthy mycelium right up until pinning. I've tossed most of my plates and am starting new ones from spore while trying to isolate healthy tissue off the most promising ones remaining.
Lost a bunch of plates, two tubs, one LC, and counting.
Also have 14 quarts that could easily be contaminated with it and there would be no way to know until fruit.
When in doubt...toss it out. But man, that was an entire bag of Pennington Classic and 5 hours of grain prep. Not man about the few $, but my few hours... 
I'm currently reading Mad Season's thread on hidden contaminants (very helpful) and figuring out if I need a steam cleaner/flowhood or not... lol
Definitely going to revise my techniques once again and if nothing else, this is some seriously good practice/experience.
I didn't even know there was a mold that could bruise blue and hide up until fruiting. Murphy's law...
Now, onto pouring plates and isolating healthy tissue. Only been doing agar a few months, and this was the only contamination I've seen out of all of my plates.
Appreciate the effort put into this thread to help others.
Here's some info on mycogone I found off google:
Mycogone. This fungal disease is transmitted primarily by contaminated casing. It infects the pins or mushroom initials as they start to form but symptoms do not appear for 10-14 days. As you say - by then it is too late. The best defense is to make sure the casing is well steamed prior to application to the beds. If necessary, treatment of the casing with 1% formalin can be used if this is legal where you are growing. Treatment of the casing with benomyl, carbendazim, prochloraz manganese or thiabendazole can also be effective. If this is a chronic problem on the farm, I suggest application of these fungicides as a preventative to the casing at every crop. There has been no reported resistance to the benzimadazole fungicides but rotation of these chemicals is always a good practice if possible. Many times Mycogone is seasonal so if you have a season of the year (typically drier) when Mycogone is not so prevalent you can suspend the fungicide treatments during those months. Sanitation and hygiene is of utmost importance and must be part of farm management year round. . If you find diseased mushrooms, weeping caps, distorted shapes, infected stipes - these mushrooms must be picked off by your best pickers wearing gloves before watering or harvest and disposed of off the farm. Watering is an important way the spores of this fungus are spread. Infected casing / compost should be isolated with heavy applications of salt or by pushing a plastic pot deep into the compost casing. Steaming after the crop has been harvested is very important to eliminate this threat from the farm. The spores can become air-borne so this must be done before cleanout.

Yes mycogone can be a pain in the ass. But it can be sometimes a false positive under a scope acording to bhod.
If my memory serves me right. I think ive grown fruits out of those plate once ive said fukit, ill try it on grains and shoeboxes.
I still wonder if i really had this contam which bothered me for months or is it something else eg. Due to Highend temp, a mutation or some bacterial response.
Hope we can identify this in the future. Will try to recreate this if i can produced fruits if i was hit by that mycogone looking plate nexttime around.

Due to lack of a microscope and unnecessary debate over whether or not TC's are right in all cases, or Bod is right in -one- case, I've pretty much stopped giving a shit as I destroyed anything that could possibly contain mycogone, and bleached all my tubs/gave them a cool water bath afterwards.
Based on what I've read steam cleaning is the way to go if mycogone ever reaches fruiting stage (which if mine was mycogone, it did), as well as certain pesticides in commercial applications for farming to prevent future rashes. The best budget steam cleaner is about 140$ on the zon' and I figured it is a solid investment for a clean freak looking to rule out vectors when I relocate.
Not a bad idea for people who live in old houses/trailers that have a really high spore load, as I've been looking at places in the country, they are common.
One clean tub does not mean that every TC has been wrong. Also stand by not feeding that nasty shit to anyone...
Whatever, people gonna do what people gonna do

 Lurking newb here, trying to read as much as possible but this site is so dense with info It would take year to read it all! ha
I have some GT LC into Pc'd Millet from 3/12. I'm ready to dump into Bod's monotub coir substrate.
I'm nt sure if my grain spawn is contaminated. I shook up last week.
I have 7 qts, 1 pic each, any thoughts from the experts? I have trouble telling contamination from non-contamination, 90 days into this journey.
 
-------------------- IN 70 days I went from Spray Kits to grain on substrate to Liquid Culture in PC'd Millet to spore swab on agar, grow tents, fans, heaters, CO2 monitors, lights, wifi controllers. I expect to be talking to aliens by December!
