Gamundia nivea sp. nov. (Basidiomycota, Agaricomycetes) from central Europe (France)

The new species Gamundia nivea is described from an Abies alba wood in France. The main features of the new species are: small size, white colour of the whole basidioma, broadly ellipsoid to ellipso-ovoid, echinulate basidiospores and very wide cystidia. A full macro- and micro-morphological description, a photograph of fresh basidiomata and line-drawings of relevant micro-morphological features are presented, together with a taxonomical discussion on the differences between the new species and its closest allies.
