Coprinellus micaceus is a common species of fungus in the family Psathyrellaceae with a cosmopolitan distribution. It is a saprotrophic species, deriving nutrients from dead and decomposing wood. The fruiting body grows in clusters and is commonly known as the mica cap or shiny cap because of the fine layer of reflective mica-like cells on the cap surface. The fungus is edible soon after collection, but after a few hours, the gills begin to slowly dissolve into a black, inky, spore-laden liquid. These C. micaceus mushrooms were photographed near Erbach an der Donau, Germany.Photograph credit: Holger Krisp
