Page number:306 
Remarks (internal):These plants differ from Rea's description of Ps. prona, Fr., in British Basidiomycetae in being conico-campanulate with an acute apex rather than campanulate then hemispherical, in the pileus not being pellucidly striate and obsoletely silky-atomate, and in the gills being moderately close, not distant, and in the stem not being flexuose. Recognised by its small size, regular pileus, thin flesh, pallid colour, fuscous-grey gills, nearly black large spores, and habitat amongst grass. Our plants resemble closely Cooke's Illustration, p1. 656, of Ps. prona.
