Slightly Purple Mycelium in Shoebox
    #25616936 - 11/15/18 05:08 PM (6 years, 2 months ago)

Hello all,

So I recently went through the process of making some shoe boxes. I started with spores to agar, agar transfers til clean, agar to WBS grain, grain to CVG mix (1 qt spawn to 1.5 qt CVG) following Damion5050's Elementary Coir tek. Everything started out great, they colonized for a week and I flipped the lid to increase FAE. Yesterday, I noticed a slightly purple hue to some of the mycelium in two of the tubs. It's not extremely noticeable and it doesn't seem to be growing, just present in some areas of what looks like tomentose mycelium. Seeing as how purple molds are a big no-no, I'm thinking it'll be best to just toss them, but I wanted to get some other opinions first.

When I search for others who have pink and purple molds, they always seem to appear in grain jars. During grain colonization, I didn't see any signs of color other than white mycelium. Since it only popped up after I moved it to the shoe boxes, I want to see if it's something different.

This is my first project with grain so I'm still learning the signs of contamination.

In this first picture, you can see the purple hue on the right side of the container (this picture is without flash)


This is the same tub with the flash on, just to show that in different light it doesn't show up as prominently.


This is the second tub.


Is the tomentose mycelium caused by the contaminant? I was thinking it may also be from lack of FAE, but I've been nervous messing with it until I have some second opinions.

Wouldn't worry about the colour..But it needs more FAE..open your lid more..Otherwise sounds as though you followed the tek to the letter, and it looks pretty good

Okay, thanks for the quick response! I just opened them a bit for some nice fresh air; when I started doing research on pink and purple molds, I went into panic mode and have been avoiding them until I got further verification that all is well.


My camera isn't the best and it seems like it didn't pick up the full color of the purple hue. But it's so faint that I can't tell for sure if it's the start of a contaminant. Have you ever heard of a purple hued, mycelium-looking contaminant that begins to appear after moving to bulk? I've only really seen cases of the purp/pink in jars.

Purple is not a normal bad colour, unless its spores dropping..Just keep an eye on it for a few days..Unless it turns green then it'd be aproblem

Is there any way it could be Fusarium, though? I just want to make sure it's not something dangerous to keep in the house.

Here's a couple pictures with better lighting from this morning. None of the grains under the surface have the slightest purple color, it's only present in the mycelium above. Do mycelium sometimes release purple hued metabolites if conditions are not ideal? I'm still weary because I've still never seen this on other peoples' bulk projects.






Thanks again for taking the time to reply to this thread! I'm a nervous nelly and I really don't want meningitis or something awful... :frown:

Its more pink I'd suggest..Which means it could be neurospora potentially

True beans. I've still got two other separated tubs so I'm hoping they don't catch the mold as well.

Thanks for the responses!
