Assessment Notes
Justification
Hymenogaster subalpinus is a widespread hypogeous fungus in western North America.
Common, especially in Douglas-fir forests of the Pacific Northwest. This species should be listed as Least Concern (LC).
Taxonomic notes
Described based on a Idaho, USA Type collection (Smith 1966).
Why suggested for a Global Red List Assessment?
Hymenogaster subalpinus is a widespread hypogeous fungus in western North America.
Common, especially in Douglas-fir forests of the Pacific Northwest. This species should be listed as Least Concern (LC).
Geographic range
Widespread in western North America, from northern California into southern British Columbia, east into the Rocky Mountains, south to Arizona (MyCoPortal 2021).
Population and Trends
Population is widespread on conifer forests in western North America. There are 51 collections reported on MyCoPortal (2021), from ~25 locations, but likely highly under reported. M. Trappe et al. (2007) say “common winter species in the Pacific Northwest”. J.M. Trappe et al. (2009), state “abundant, southern WA to northern CA and northern ID”. No decline has been noted.
Population Trend: Stable
Habitat and Ecology
Ectomycorrhizal with Pinaceae, especially Douglas-fir (Pseudotsuga menziesii), from low elevation to montane forests. Fruit bodies hypogeous, fruiting in late fall into spring This species is likely dependent on mycophagy (primarily eaten by small mammals) for spore dispersal.
Threats
No specific threats have been identified with regards to this species.
Conservation Actions
No specific conservation actions is needed with regards to this species. Modern taxonomic research should be done on Hymenogaster in western North America.
Research needed
Modern taxonomic research should be done on Hymenogaster in western North America.
Use and Trade
None known.
