Conocybe mesospora

The genus Conocybe encompasses numerous species with very similar macroscopic features, making exhaustive microscopic examination indispensable.

The species treated here is large for the genus, reaching up to 5 cm in diameter.

Its hygrophanous cap varies in color from orange to brown, with a pruinose, whitish stipe that widens at the base.

The study presented here is based on a collection made in June in the middle of a forest track, in a humid woodland area under oak trees (Quercus rubra and Q. robur) in the municipality of Erandio (Bizkaia).
