glowing mushroom/fungal culture

[RandyFulle]

Bioluminescence in Armillaria mellea is a very common occurance. In fresh
cultures in petri dishes it seems to last for a couple of transfers and
then quits, no answer as to why. In the field A. mellea forms fans under
the bark of dead and dying trees and at night when you peel back the bark
the light show is quite spectacular. The spores of A. mellea are also
known to possess bioluminescence.
