Agar plate turned gray

Scratch · 05-12-09, 01:24

Started this plate with a drop from spore syringe on pda.
Yesterday this was all white with steady growth.
Today it has turned gray.
What went wrong?

Dont see any gray but I see green but I guess that is food coloring in you agar or lighting. Everything looks okay to me.

There is still a bullseye of white in the center and a ring of white around the outer edge.
In between was white yesterday and turned gray today.

The agar has lovely green food coloring.

Never had a culture turn grey like that. I have had P.mexicana turn brown, but that's P. mexicana.
Is that a cube strain?
