Comatricha longipila Nann. View in CoL - Bremek., Acta Bot. Neerl. 11: 31 (1962)

Type:— NETHERLANDS, Gelderland, developed in moist chamber on bark obtained from a living oak, 7 April 1961, N.E. Nannenga-Bremekamp, BM 4839 [ BM 001088435 = box, BM 001247192 = slide, BM 001247200 = SEM stub].

Nannenga-Bremekamp (1962: 34) compares Comatricha longipila with C. laxa Rostaf. and C. subcaespitosa Peck. The latter is considered nowadays to be a synonym of Stemonitopsis subcaespitosa (Peck) Nann. -Bremek ( Nannenga-Bremekamp 1991). The latter two species have larger spores, an observation which is confirmed by our measurements. A study of the types of these species was carried out by Castillo et al. (1997) and Moreno et al. (2004) respectively. Our images show that Comatricha longipila has a capillitium similar to species of the genus Stemonaria Nann. -Bremek., R. Sharma & Y. Yamam., but the solid instead of a hollow stalk, separate it from species in that genus.
