On the application of the name Agaricus Lacrymabundus Bull.: Fr

In literature the name Psathyrella lacrymabunda (Bull.: Fr.) Moser is being applied to two species which in this note will be called Psathyrella cotonea (Quél.) Konr. & Maubl. and Lacrymaria velutina (Pers.: Fr.) Konr. & Maubl. or ‘L. velutina’ s. auct. Taxonomically the distinction between the two species involved offers no problems. The former is keyed out satisfactorily by Kühner & Romagnesi(1953: 370) as Drosophila cotonea and by Moser (1982: 272) as Psathyrella cotonea, in both cases with reference to Lange’s plate (1939:) 146C; the latter by Kühner & Romagnesi (1953: 371) as Drosophila velutina and by Moser (1982: 272) as Psathyrella velutina, in both cases with reference to Lange’s plate (1939:) 144B.
