Grey Inkcap
Coprinopsis cinerea, the grey inkcap, is a small dung-inhabiting inkcap whose caps deliquesce (dissolve into black ink) after releasing spores. It is a major model organism for research on mating types, mushroom development, meiosis and the evolution of multicellularity. In culture it fruits readily on agar plates under alternating light and dark.
Reported as edible but rarely eaten: it is small and must be cooked within hours of picking, before it dissolves. It is easily confused with other small inkcaps whose edibility is unknown, and with the common inkcap C. atramentaria, which causes a coprine reaction with alcohol. Not recommended for foraging.
Never eat a wild mushroom based on a web page — confirm with an expert.
