Name: Psathyrella carbonicola
Author: A.H. Sm.
Citation: Contr. Univ. Mich. Herb. 5: 31 (1941)
Synonym(s): Psathyrella pennata (Fr.) A. Pearson & Dennis
The holotype location is Booth, Oregon – Near lake Tahkenitch.
“Fries in his various works describes the gills of Agaricus pennatus “livido fusco-nigricantibus” a feature not applying to P. carbonicola. Hence I do not accept the synonymy proposed by Kuhner & Romagnesi (1953)."
I do not think that a colour variant of the gills is nearly enough to constitute splitting two species which are otherwise indistinguishable… I also take into consideration phenotypic variation within taxa.
On the flip side, P. pennata is described from Europe, and P. carbonicola is described from the West coast, US. It would be good to compare collections of each before deciding if they are certainly the same.
