Notes on the genus Psathyrella—VII. Psathyrella longicauda versus Psathyrella atrolaminata (= P. melanophylla pr. p. maj., excl. type)

The name Psathyrella melanophylla proposed in our previous paper (1976: 370) to replace the misapplied name P. caudata, is in its turn replaced by the name atrolaminata as a result of the discovery that in our previous paper a collection belonging to P. longicauda had erroneously been selected as the type of P. melanophyllum, which renders the latter name a synonym of P. longicauda. It is argued that Ricken’s plate 68 fig. 1 (1913) does not represent P. atrolaminata as erroneously stated by Kühner & Romagnesi (1953: 359) and us (1976: 370) but P. longicauda. A redescription of both species is given.
