It's just mycelium, and it looks like there are some knots forming nearby :thumbup:

Thanks for the advice! It's just weird to see mycelium grow up from the medium.

Amazingly helpful (and unnerving) index, especially useful are the pics of various contaminants. This must have taken months to put together. Fantastic work!

I must admit, though, I'm a little confused by this paragraph:

"Overlay - A common sign of Trichoderma is mycelium that colonizes over a casing layer or the vermiculite fruiting PF cakes have been rolled in. While mycelium can also create overlay, if your fruiting conditions have been adequate to prevent it, this can be one of the first signs you notice."

I'd love some clarification if and when you have the time or inclination.

Again, beautiful work! Thank you!



Thanks for pointing that out. In part it's confusing because I meant to upload some better pictures later but I also rewrote it so it makes more sense. Basically what I meant is when you notice mycelium growing over parts of the substrate you normally don't see it growing particularly in comparison with identically made substrates. When you have an actual casing layer you normally aim for it to not be colonized, and to mostly have rhizomorphs growing through it but then suddenly there's this patch growing over it and...
:scream:




Thank you so much for the clarification! Much appreciated.

Looking for verification. [Re: Kizzle]

First time for everything first grow, first flush, new member, and first post.  I am using rye berries in 110 quart mono tubs, with six 2 1/2 inch air exchange holes, three high and three low all stuffed with poly.
Everything has gone well until I put my myc in the mono tub. The first time I watered them I bruised one tub very badly and the other not so much. Thought I had contamination and freaked out. Now thanks to this site, I have learned to mist my tub’s and I have pins popping all over. Oh yes these are golden teachers on day 7 since the first pins appeared. I have a couple with fuzzy feet that I think is from poor fae, but with my poly and I fan them with each misting(up to 5 times/day if I’m home) I want a more experienced opinion. Thanks in advance and Thank You greatly for all the info on this site.

It's very dry in there. Awesome job for ur first grow though!!!! Next time try making the poly on the bottom a lot tighter to hold the humidity in. If u dial in the tub right u shouldn't have to mist much.

Fuzzy feet are hard to avoid too. And it can happen from misting too. Ur on the right track tho man, I can tell uve been reading for awhile :smile:

Thank you. Glad to hear I’m doing something right lol. First flush gave me just over 5oz of dehydrated product between the two tubs. Somewhere I read to pluck em soon as the veil tears, so I ended up with a bunch of little ones. Towards the end of the flush I read that it doesn’t hurt to let them spread their caps, the last few were huge. Any input as to which way is best?

They say for potency it's best to pick early. And f ur trying to avoid spores all over ur shrooms. Otherwise it doesn't hurt to let them open. If u want max weight without getting spores everywhere, pick the ones with open caps b4 they drop spores everywhere, and leave the rest till they start to open up.

At the end of my second flush I had spores drop, now 3 days later there is no new growth except for this (see picture) in one corner. Is my tub done for? Or can I cut out this corner and see what happens?

No it's done. Put it outside, it's compost now.

I have just tried to inoculate some jars with two different spore syringes  on the 20th and I have started to have Cobweb mold in them. Do you think my syringes are bad or what is going on? It seems the cobweb mold starts at about the 3-4 day mark and I don't believe it is the syringes because the mold started on the outside of the cakes and I inoculated them straight down into the substrate as I did not know I was supposed to inoculate towards the glass. What is going on and how can I prevent this? This is my first time doing this and so far it has been very dissapointing, I already have to chuck out 5 jars and I don't want to waste anymore solution or jars.

Sterilize ur jars longer. Cobweb mostly comes from not sterilizing well enough ime.

And yes, next time inoculate toward the glass so the water drips down the glass. It's easier to monitor growth.

Newbie question:

When I cut my shrooms to dry, I noticed blue-green everywhere I cut. Is this contamination? Is it bruising? Are these safe to eat?

Getting started with agar and this pink dot showed up on one of my plates.

Anybody that could help identify and can I just cut it out of the plate ?

On the list of non contaminants, you should include primordia. I had a bunch of yellow/brownish blobs form in my jars, and I thought it was some sort of bacterial infection. Come to find out it was primordia that eventually turned into knots and pinned. Probably just a rookie mistake, but since the point of this forum is helping rookies, it might be worth adding. Just a thought!

That's thrich. It'll be green shortly. Good eye. Most new people don't notice mold till it changes colors.

I got a nice flush out of these cakes, but this one had a good bit of blue bruising throughout the whole process. I dunked and rolled in verm for a second flush last night and about 14 hours later, I noticed that this patch where it was very blue is now looking awfully dark and almost gray. I think it's just bruising getting worse on that spot and i'm gonna keep an eye on it. Anyone more experienced think it looks more like a contam?

Hi Folks,

  There's a long black thing in my grain jar. It's coming out of a particularly dark oat. I don't think it was there before. It looks like some kind of stroma. Admittedly, I haven't paid much attention to this batch, and it could've been there all along.

Also, I know the moisture is too high in these jars. My mistake. Please don't drag me.

Have you seen anything like this before?

Thanks!
