Holotype: New Zealand. Sine loco (probably Wellington), C. Knight s.n. – H-NYL 22708 [erroneously chosen as lectotype by Mason Hale (1981: 314), since the ascospore measurements written by Nylander on the packet " sp. 1 fuscae, 0,140–0,200 0,025–0,032" agree precisely with the protologue. The H-NYL specimen is, moreover, annotated by G. Salisbury as holotype (Dr O. Vitikainen, pers. comm.)]. Isotype – G.
