What specifically causes cobweb?
    #3312964 - 11/03/04 07:07 AM (12 years, 1 month ago)

Yesterday I put a dozen casings in the fruiting chamber,1 casing had a good case of cobweb and I immediately tossed it. (While they were in the incubator they were in sterlite containers with the lids on)
  Now today when I checked in on them there was the beginnings of cobweb on a couple other casings. Only a few small spots though. So I am going to try to segregate the infected ones and combat them with peroxide/water mixture.
Is there something that particularly causes this? Is there any extra precautions I could take to prevent this? I also had 2 quarts out of 85 that was contaminated with the dreaded cobweb as well,no other contams have been a problem so far with the exception of the dreaded cobweb. :smile: :confused: :mushroom2: :mushroom2: :mushroom2: :rasta:

Obviously, cobweb mold spores.

You need to be cleaner.

It sounds like your house/work area is contaminated with cobweb mold(spores).

I think now you know why we cover our casings with foil =)

Are you sure it is cobweb and not mycelium?
Check the contamination faq
http://www.shroomery.org/index/par/23418
for images of cobweb and compare to what you have.

i cant see using alum. foil lid rather than the lid that comes with the sterlite containers inducing any less contams. If both lids were properly whiped down, there shouldn't be a difference. If neither lids were not whiped down, there shouldn't be a difference.

I'm pretty darn sure it isn't myceleum. It looks just like the cobweb that quickly overcame 2 of my quarts.
I just sprayed it with water/peroxide and it seemed to disappear as it was sprayed. I will be keeping a close eye on it! :smile: :mushroom2: :sun: :rasta:

Lids are air tight, foil is not. When you introduce a moist casing layer ontop of a nutrient rich substrate, you are going to have moisture buildup. Without ventalation, that is a contam hotel.

I have never run across a rubbermaid/sterlite container that had an air-tight lid. Infact, I would say that tinfoil has the potential to be more air tight than any tub lid.

I used both cling-wrap and tinfoil on my casings.

That isn't his problem. Cobweb mold or any other contam doesen't just spontaneously sprout up. He needs to keep the contamination from reaching his substrate in the first place.

An ounce of prevention is worth a pound of shrooms. Or something.

Dont listen to me then.

That isn't what we're trying to say.... I wasn't trying to come across like an ass or anything, but it's true. Examine any tub lid.. You will find that most of them are warped and don't even come close to sealing. Many of them have reinforcement bridges that flat-out prevent sealing, because in most cases you want the things you're storing to be able to breathe.

Just apply the same logic that applies to jars. They have very little ventilation, but they definately don't contam just because of that fact.

There is only one explination, that there are cobweb mold spores somewhere in his environment. Some got onto his casing substrate, and germinated. He could leave his casings out in the open with no cover at all, and if there are cobweb spores present, they will land and grow. The bottom line is that he needs to be more sterile in his environment, practices and procedures.

:smile:

discman and I have no contams. I was just saying that your evidence doesn't support your theory. Mold doesn't just appear because of conditions, it must germinate from spores.

Most of them ARE sealed and pretty damn much air tight. The spores are introduced during making the casing. Note the poster says it quickly overtook 2 jars. This means the spores were in the house. The casings weren't made in a sterile enough enviroment the mold spores landed..were covered with something that holds in air MUCH better then tin foil. Kept it stagnant and started them going.

Sorry guys but listen to Citrics experience at this point, he's right, he just didn't explain that mold spores are everywhere and land on your casing and airflow is what helps to them to not germinate.

You're kidding right? A tub will not hold any positive or negative pressure. It won't even hold water. Try it; put some water in one and turn it upside down. It will leak like a sieve. The reinforcement ribs that line the sealing-edge of the lid physically hold it off the sealing-surface of the tub.

There is a 1/8" or so gap between the lid and the tub all the way around on mine.

Here's a pic of the ribs to illustrate:


Tubs and their lids are mass produced, they aren't precision and most only have two latching points.

I tried maybe a dozen lids on half a dozen tubs when I was shopping at wal-mart, and picked the two that fit the best together. It is still warped though - the NE and SW corners don't even contact the tub, you can press them down with your fingers, but it's not as bad as some of them were. I'm pretty sure that I could get foil to seal better than the lid on any tub.

It doesen't matter though, we both agree where the problem is - in his house/work area. It's just that we need to cite the correct problem or it isn't going to help him find a cure. He asked what "causes" cobweb mold, and the correct answer is that cobweb mold spores do. Even if anaerobic conditions are a contributing factor, that is not the cause.

Sorry, I don't mean to sound anal... I just don't want there to be any confusion.

:smile:

Edit: I would like to add that I could be thinking of completely the wrong tubs. I was assuming that these are rubbermaid-style tubs, not tupperware which does have positive sealing all the way around the circumference of the lid. If that is the case, I appologize.

Were talking about Sterilite containers..the small ones used for smaller casings of a quart or so DO seal airtight. I just did go grab one and fill it with water and flipped it. I also did so with glad containers I have, shoebox containers (the plastic ones with snap on lids), and tupperware containers. All of which held upsidedown without leaking.

yeah i dont think anyone is talking about his terrarium but more his casing boxes which if i used the lids for mine theyd seal pretty damn near airtight

Weird, what model number/size are your containers? That is exactly what it is.. in that picture that is.. a small sterilite tub. It wouldn't hold water if it had to(while upside down)!  :shocked:

I'd be interested in some of the ones that seal better.. I'll have to go looking around.
