How to identify cobweb in grain jars. * 1
    #19080507 - 11/03/13 02:01 PM (10 years, 3 months ago)

A few days ago I got some cobweb on a petri dish along with some mushroom myc.




I have noticed people have a hard time identifying cobweb until they have seen it for themselves. So I took some good high res, appropriately white balanced pictures of cobweb contamination. These should look as close as possible to what your own eye would see.

I myself wanted to know what cobweb looked like on grains for reference. So I took that dish with cobweb and took a big hunk of cobweb/cube myc and put into a jar.

Here's what it looks like after a shake at what was about 20%.









So this last picture clearly shows the wispy cobweb running through the grains in between the healthy cube myc.

What is interesting to me is that the jar only got the condensation after the shake. The grains were prepared correctly and not too wet. After the shake about a day later all the condensation appeared. I am clueless as to why but I thought maybe it was heat from the cobweb ripping through the grain but it really beats me. Other grain jars prepped at the same time look great.

Edit: this may confuse some the rest of the jars I did in my PC run were inoculated with clean cultures. The one contam jar was an on purpose just to get cobweb in a jar so I could see it with my own eyes rather than only have seen it in pictures. And to add some good pictures to the forums.


Here's some more
A cobweb explosion.
This is from a dish that had cobweb that I didn't bother trying to isolate away from onto a new dish.

It's interesting because the mycelium took off before the cobweb did for a few days and then over night this happened. Must have been cobweb spores that got in. Perhaps it was my sterile technique or the wedge(I hoped was clean 180ยบ away from the contam) from the dirty dish I used had some cob myc or spores on it.

Yes the condensation is because its warm and humid from the heat the myceliums putt off

It doesn't matter what i think of you...all that matters is clean spawn

shaking wet jars will redistribute the water.

just picture tossing a pile of h-poo, when you get to the middle you feel the heat coming off

More growth is why that one got wet and the other ones did not.

I bet if this was G2G you will see the rest show sings of cobweb, I think cobweb turns green, if not you have trich as well.

it is easy to identify cobweb in jars or on any substrate. just wait 2 days and it overruns all kinds of substrate:D

What do you consider cobweb? If you're talking the pathogen mold that grows on mushrooms and causes cobweb disease this is a culture transferred from another culture derived from a cobweb infected mushroom. There are various species that can look a little different but they all produce these similar and unique fruiting structures you can see on top left once they start sporulating. The mold you have there looks like countless other similar appearing molds that commonly contaminate grain jars. Cobweb is a pathogen it feeds on live plants and fungi, I doubt you would find it colonizing grain like that.

But like the only to be sure if something is cobweb particularly in a culture is to let it grow until it sporulates. If you're interested I made a whole post about it here with some good pics.

The whole purpose of this was I used a bad petri dish that had cobweb on it to inoculate a grain jar on purpose. This was just to get really good pictures of it to help out any one who might use my pictures as reference.

This is an isolated jar. I didn't g2g it it's not contaming anything else of mine. It was an on purpose for documentation.

I know I'm just saying not all grey fuzzy mold like that is cobweb mold, just mold. The actual definition of cobweb mold, at least in majority of the mushroom community, refers to the specific pathogenic species that cause cobweb disease.

You could fruit them to further the experiment, and see if you can keep the cobweb at bay.

If the library was with your OPs only, I would indeed hate it.  Thankfully this is a thread where knowledgeable people can comment and clarify and submit real, valuable information, such as Kizzles post above. In all reality, this could even be worse than just a repeat, it could just be more misinforming or confusing than anything else.

Where are the characters and information on how to identify it? You didn't even provide a species name!  Cladobotryum dendroides, C. mycophilum, etc. (formerly Dactylium spp.) It's hard to tell if that's even cobweb with most of those "hi-res" pics. Not to mention this forum has plenty of pics of this idea already.  You could have easily submitted them to better posts that are already asking for pictures rather than starting another thread and cluttering up the forum.

U mad bro. Way to be a non-contributionalist asshat. I'm sure part of it is your personal vendetta for me telling you not to tell a noob spawn cakes to a sterile growbag.

Most people here are not scientifically trained. The images are to show people what one common contam looks like. If you don't like it you don't have to post here. You can just continue to do even less good than these pictures will somewhere else.

He has earned a lot in the last couple days.

I have never seen someone take calm advice so bad and then get this out of hand with it. Looks like the age verification part of this site could use an upgrade.


Anyway.
Most people use "cobweb" as a generic term to describe any wispy off white mold that's not cube mycellium. It's been working well for years. In general we don't need to know what kind of contam we have since they're all bad and worthy of tossing jars. We only as hobby cultivators need to identify healthy cube myc from any other growth and that's the only purpose of what I posted above.

Completely Bogus. So much bromance going on with you gals.  Not to mention you're being bigger jerks in response.  Its part of the forum to not unnecessarily repeat posts.  And if you read my post there is information in there.  Sorry this isn't "your" community, the Mushroom Cultivation forum is a place for information and this post is basically not helpful! Totally within the guidelines of response to an OP...

The thread is titled "how to identify..." and so bod your last post completely contradicts that and just reiterates how unnecessary it is. It's easy to use the search function.

This is possibly an example of something immediatley thought of as cobweb, could be cobweb.. could be anything else..

We'll see.

I don't recall a worse case of being a douche-bag. I'm continually amazed by the amount of bad information you've posted in such a small window. You have to be a troll. You are spreading bad info on purpose because nobody could possibly be as stupid as you.


bodhisatta, keep doing what you do and ignore this dick. I haven't read one single good post by him/her.
