Hygrophorus calophyllus (Alb. & Schwein.) Dumée, Grandjean & Maire (1912)

Collection Sierra Nevada -- the pinkish cast in the gills suggest closer association to calophyllus. It is unclear how close the Western American material is to the European where the pinkish gills are more pronounced.

Collections from the Colorado Rockies. Faint pinkish tones on the gills obscured by browning due to age.
