Thanks, Phil.
Any thoughts about the greenish-blue colorants in Penicillium sp? Or magenta produced by some Fusarium sp? Ann -----Original Message----- From: mycology-bounces@...

The blue-greens - sorry, I don't know but the same melanins as in the dematiaceous fungi are also in A. fumigatus and some others and have the same antioxidant protective role in virulence.
