A new species of Entocybe (Entolomataceae, Agaricomycetes) from Quebec, Canada

Entocybe melleogrisea sp. nov. is described from a subboreal forest type in Quebec, Canada. The stature of this species is robust and tricholomatoid and thus is very different from the mostly collybioid species placed in the genus. The distinctive basidiospore morphology, basidiospore histochemistry, and prolific, obvious clamp connections on all hyphae of the basidiomata place this species in Entocybe. Preliminary data on ITS sequences support this placement.
