Mycena polyadelpha is a minute white species of Mycena which is found on dead Quercus
ilex leaves and seed capsules. It is very common in localised areas but is probably
overlooked because of its very small size. There are many similar species growing on
Quercus leaf matter.
The pileus is convex, translucent white, thin and smooth. Gills are white, distant, few in
number and decurrent (arcuate). Stipe is thin, transparent relatively long, without a basal
disc and slightly hairy around the basal area. Spore Print:White
