Assessment Status Notes

An uncommon species with only 22 records on Mycoportal and no reports on Mushroom Observer, however these collections are spread across northern USA and southern Canada. If the western species can be shown to be a different species from eastern collections, this possibly could be revisited. Until such time, this should be listed as LC.

Taxonomic notes

This species belongs in the genus Cuphophyllus, but has not been transferred yet.


Why suggested for a Global Red List Assessment?

One of 13 species named for Mt Rainier, which is now a protected island of old growth forest surrounded by clear-cuts, and forest managed as ‘tree farms’. There are very few modern collections of these species, and this one was used to highlight what is now considered a restricted and fragmented habitat.


Geographic range

Originally described from Mt Rainier, WA, there are 20 records scattered across northern USA and southern Canada.


Population and Trends

Only 5 of the 20 records on Mycoportal are post 1970
