Lepiota cristata - Stinking Dapperling

Taxonomy

Phylum: Basidiomycota

Class: Agaricomycetes

Order: Agaricales

Lepiota cristata, the Stinking Dapperling, is one of several small, dapperlings many of which are poisonous. A transient ring and a smell of coal gas are characteristics of this woodland mushroom.

Until recently, dapperlings were more commonly referred to in Britain as parasols; a confusion that may have added to the risk of poisoning, as the large Macrolepiota species, commonly known as parasols, are good edible mushrooms.

Similar species	Lepiota ignivolvata is very similar in appearance except that it has a bright orange or red-brown ring low down on the stem.
