Cleistocybe

Cleistocybe is a genus of fungi in the family Biannulariaceae.^[1] Basidiocarps (fruit bodies) are agaricoid, similar to those of Clitocybe, but with ephemeral traces of a partial veil and decurrent lamellae that are often greyish. The genus is separated on DNA characteristics as well as morphology.^[2] Species are known from North America, Europe, North Africa, and Tibet.^{[2][3] [4][5][1]}
