Cloudy agar?
    #12568908 - 05/15/10 06:53 PM (14 years, 8 months ago)

Hi guys! :smile: :smile: :smile:
I'm not sure what is going on here. My petri dishes are cloudy at the top, except for the immediate environs of the mushroom tissue. It can be scraped off with a scalpel. I can't really detect a smell other than the mushroom mycelium (valvariella volvacea). You cant tell in the picture, but the mushroom mycelium is growing over the cloudy stuff. Is this a yeast contamination? My agar boiled over heavily, and I poured it while it was still very hot- could this have something to do with it? I poured the plates 4 days ago. I didnt see this until recently because the lids were heavily condensated and I couldnt see through them. Today I lifted the tops.
