NOTES: Lister (1898a: 120) commented “The brown variety with a symmetrical cup (referred to in the Brit. Mus. Cat.

Myc. p. 148), though less frequent, is also cosmopolitan, and is so little subject to variation that it deserves a varietal, if not a specific, distinction. I mark it as var. fuscum .”. In BM we found two collections, BM 2775 is the best sample and collected by the author, and so we designate it here as the lectotype. The BM 2778 has two fragments on a cardboard .

The fragment marked “ss. v. fuscum ” we consider to be a syntype. Some authors such as Nannenga-Bremekamp (1975,

1991) still recognise this variety, but others don’t ( Martin & Alexopoulos 1969).
