Coprinopsis spelaiophila is a small, delicate, deliquescing mushroom of the Coprinopsis genus which members have a whitish cap and a white stem. This a type of mushroom that is called an inkcap because when the spores are shed the depleted gills dissolve (auto-digest) first into a clear liquid then into a black fluid containing the black spores. When all the spores are shed only a black stained stalk remains. Coprinopsis spelaiophila is 'distinctive' because of the big tufts of veil remnants on the cap. The scales on the cap age quickly to become dark in the cap centre.
They are usually found inside hollow trees on rotting wood... The scales on the cap age quickly to become dark in the cap centre, so seeing a pure white cap is in itself unusual.
