first grow. Trichoderma?
    #26393989 - 12/21/19 12:44 PM (4 years, 1 month ago)

Greetings people of earth (and beyond)!
This is both my first grow and first forum post. please forgive any mistakes.

I never event expected my first attempt to get this far without any issues but it seems my good fortune has come to an end and I think my improvised straw log has been contaminated, probably trichoderma?

I'm looking for a bit of advice before doing anything drastic. Like cutting it half trying to save it.

That green color on white cauliflower is definitely some sort of contam. I am no expert, so I can't tell you what that is exactly and whether or not you can eat that fruit. I wouldn't, but I might be wrong. But I wouldn't if I wasn't 100% sure.

Also, I think there is a second contam going on — the shape of the fruit itself, the brownish color of the dry stem and stupid-looking caps are all symptoms of verticillium. Healthy cubes do not look like that at all.

Here is a quote from Stamets's book on verticillium:

316, The Mushroom Cultivator
Macroscopic appearance:
"Slightly infected mushrooms characterized by brown colored spots or streaks on the basal or upper regions of the stem and on the caps of developing primordial. These
spots become grayish colored from spore production. Afflicted mushrooms often bend to toward the
side that is infected. If the mushrooms do develop at all, they are typically tilted to one side or the
other. Verticillium attacks developing fruitbodies. The more severely infected are grossly malformed, especially young primordia which are turned into sclerotia-like balls of amorphous whitish
mycelia. More mature but diseased mushrooms have a deformed pileus, sometimes with a "hair
lip", and frequently with a downy grayish mycelium over the cap. The stem can be covered with a
downy mycelium and often vertically splits, roughly resembling a peeled banana. The cap becomes
disproportionately small relative to the fatter than normal stem. The overall texture of the mushroom
is dry and leathery.
When this mold attacks Psilocybe cubensis, there are several additional characters worthy of
note. Parasitized P. cubensis caps frequently become plane at an early stage. The stem becomes
swollen and hollow, narrowing radically towards the apex. Only in an extremely humid environment
does a downy mildew develop over the cap and stem surface. The "Verticillium spots'' so commonly reported by growers of Agaricus. a white mushroom, are more accurately called "Verticillium
streaks" on P. cubensis. a mushroom with a brownish cap and a whitish stem."

I suspect that this fungus is also involved in the mayhem on your cake. You could eat verticillium-infected fruits, however, as they are nonpathogenic. All you have to do is dry them completely in a food dehydrator or make tea out of them. Having said that, the toxicity of your green contam is what I would worry about.

Bummer.

I decided to essentially cut it in half just to see how it plays out.
If I see no more signs of mold I might dry and try them, but most likely this is a toss.

Thanks for the info!
