Comatricha typhina f. pumila
[It may have been based on "Stemonitis pumila Corda," which Rostafinski cites as a synonym of C. typhina (F. H. Wigg.) Rostaf. Corda, Ic. Fung. 5:59. 1842, proposed no such species but merely referred his material doubtfully to S. pumila Fr., Syst. Mycol. 3:159, 1829, which is also of doubtful identity (apud Martin & Alexopoulos, Myxomycetes 240. 1969)]
This name is a synonym of:
Stemonitopsis typhina (F.H.Wigg.) Nann.-Bremek.
