I think it would be beneficial to have a thread focused on showing photos of different types of contaminations


I'll start off with this- And post some photos of some inteeeeeeresting looking agar plates later this evening




Bottom of my unlined tub- and there were splotches of that blue/grey (that I think is mycelium bruising due to stress from some contam) on the top of the tub as well- That yellow bit clearly looks off too.



Lets see your photos of your attempts to grow uninvited volunteers!

This is a site I have found very helpful over the years for identifying contaminates. At this point I have personally seen a lot of these and no longer need the reference but it is helpful for people who are dealing with things for the first time...




Just fyi in response to a previous post of yours, at least I think it was you... I never use liners in my tubs... I have found that I still get a lot of side and bottom pins whether I use one or not... I just pull the sub out of the tub while harvesting, remove them, put it back in the tub, and pour water in for a dunk... I use smaller tubs and bags so it is easier to pull out and handle than if I were doing a monster size tub... The mushrooms on the sides and the bottom will at times get a flatter appearance but it all works the same... Since I dunk in the tub and since the liner has never clung to the substrate very well for me and I end up with side pins anyway, I have never had much use for a liner... I feel like it is just an unneeded step that's a pain in the groin that I don't care to deal with... The liner always gets in the way for me and is a pain when I am trying to add and pour off water for the dunks...

Thank you for that! 


I noticed that the tray I had with the liner in it still got massive side/bottom pinning. And the mono I have that is unlinered seems to have relatively few- I've read somewhere that a level surface of the sub has something to do with promoting more even evap and thus less side/bottom pins but I've yet to actually create a level surface to a tub- Make that a priority next time.

Tried to germinate my spore syringe. Not sure what this is, did the spores even try to germinate? should I have tried transfering or were these doomed to begin with?

That looks kinda like yeast,
I had the same thing happen to me with my pan cyan spores.
Could be the wrong medium for your spores.

Really, I was kinda suspecting my syringe, I bought the cheapest off the internet, it's a pda I'm using btw.

So I took a bunch of contam pics last to add to this discussion. Please comment on if you agree or disagree with what im describing, I'm a noob making observations.

Pic 1 shows what I believe to be mycelium and cobweb mold sharing the dish.
Pic 2 more mold and mycelium with a few baby aborts
Pic 3 is some good mycelium with a splotch if trich in the middle.. could this one still be good. Splotches up top are reflections.
Pic 4 transfer of (mycelium? I hope) out of contaminated dish
Pic 5 mold right?
Pic 6 I think it's all cobweb, weird rope formation circles
Pic 7 left over agar that went bad, ketchup cups still contam free, bad seal on mason jar maybe.

Hope this helps us all thanks

I found this grayish white mycelium growing next to shroom spore and wondering if anyone can ID it. (Cobweb?) I pulled it off the cake and now a day later that "contamed" material looks better than the cake. Did I panic over nothing? Since it seemed to be doing better I put it into it's own tub and will keep an eye on it.

Is this contamination? The culture itself is looking a reddish maybe pink color, the spores are from some penis envy uncut, as I have not grown this species before I dont know if such coloration is natural or not
