Agar contamination- do you know what it is?
    #26355241 - 12/01/19 09:37 AM (4 years, 1 month ago)



This one has a yellow stain where the LC contacted it



This one has something at 3:00 where there is a blue ringed contamination and it looks like there is mycelium growing on top of it.

Any ideas?

Got pictures from a microscope? Even with those genus level identification at best.
For all practical purposes what youve got is contamination.

Literally hundreds of species of bacteria would make the same looking growth on agar. Molds are a lot easier to identify but still it's just a contamination at the end of the day

The green contamination is maybe aspergillus or cladosporium it doesn't look like trich but people just call all green mold trich

Yeast and mold. The mold has mold mycelium. The green pigment in the mold is spore-specific, so you probably don't want to open that dish near your shroom working area (or at all).

I don't have a microscope, so can't answer that one.  Not totally worried about the culture, just wondered what it might be. I'm going to get rid of it and sterilize the dishes.    The yellow in particular threw me for a loop as it followed the entire area where the LC came into contact. I'll stick with my spore print transfers instead of LC going forward.
