Help Identifying Contamination on Agar

#26073642 - 06/25/19 07:07 PM (7 years, 1 month ago)

I have read this forum for several months, but now I need help identifying contaminations. Some contaminations I caused on purpose and others have been inadvertent.

The first tek I read was by Bodhisatta how to make agar. The recommendation was to pour several agar plates as practice and see the result of my cleanliness.

I used a still air box and poured 50 plates using 10g agar, 10g LME, and 1g yeast flakes in 500ml distilled water pressure cooked 15psi for 45 mins. I had one contamination out of 50 poured dishes after 2 weeks. The contamination looks fantastic, and I would like help identifying what it is exactly.

I cloned my first mushroom from an oyster I grew in a kit from Home Depot. The original clone samples were riddled with contaminations, and I let one battleground plate continue after the second transfer of what I think was good mycelium.

As of the 3rd transfer, the oyster mycelium looks like this:

Thanks for everyone's help.
