Mica ink cap

coprinus -> corpinellus or coprinopsis ( new taxa) are divides in autodigestion of the gills/spores. all coprinus are ink-mushrooms ---> the spores liquefy and come out similair as ink. The most of the genus coprinus are curling upwards. i identify this one mostly from it stem. there are 2 species which look very similair. --> coprinellus micaceus and truncorum. the cap is almost identic but the stem of the truncorum is smoother and whiter. (normal mica ink fungus / smooth-stalked mica ink fungus ) {ruffly translated from dutch} the coprinellus truncorum has the smooth/ white stem. but those 2 species here in dutch,maybe you will find here ( http://eol.org/pages/16701/overview ) a similair species from your area.
