Extract from Wikipedia article: Coprinellus micaceus is a common species of fungus in the family Psathyrellaceae with a cosmopolitan distribution. The fruit bodies of the saprobe typically grow in clusters on or near rotting hardwood tree stumps or underground tree roots. Depending on their stage of development, the tawny-brown mushroom caps may range in shape from oval to bell-shaped to convex, and reach diameters up to 30 mm (1.2 in). The caps, marked with fine radial or linear grooves that extend nearly to the center, rest atop whitish stems up to 100 mm (3.9 in) long. In young specimens, the entire cap surface is coated with a fine layer of reflective mica-like cells that provide the inspiration for both the mushroom's species name and the common names mica cap, shiny cap, and glistening inky cap. Although small and with thin flesh, the mushrooms are usually bountiful, as they typically grow in dense clusters. A few hours after collection, the gills will begin to slowly dissolve into a black, inky, spore-laden liquid—an enzymatic process called autodigestion or deliquescence. The fruit bodies are edible before the gills blacken and dissolve, and cooking will stop the autodigestion process.
Coprinellus micaceus is a small to medium-sized agaric fungus that grows in clusters on stumps, decaying wood, and other organic matter. In St. Petersburg and Leningrad Oblast, it typically fruits from June to October, with peak abundance in July and August. The species is common in urban areas, including parks and gardens, as well as in natural forests of north-western Russia, where it can be found growing on a variety of substrates, including birch, aspen, and alder. The fungus has a bell-shaped cap that ranges in color from yellowish-brown to dark brown, covered with fine, shiny particles, and a slender stem that is typically 2-5 cm tall.
