Assessment Notes

Justification

Gomphus bonarii is widely distributed and very common throughout the higher elevation forests of the western United States. In many years, it is the most commonly encountered macro fungus in the Sierra Nevada and southern Cascade Range; no sign of decline has been noted. This fungus should be listed as Least Concern (LC).


Taxonomic notes

Described as Cantharellus bonarii (Morse 1930), then transferred to the genus Gomphus (Singer 1945.).  Phylogenetic studies (Giachini 2004, Giachini & Castellano 2011) used conserved genetic regions to synonymize this name with Turbinellus floccosus. Other lines of evidence suggest that G. bonarii should be recognized as a distinct species. However, it was directly synonymized with Turbinellus floccosus (Giachini & Castellano 2011), and not transferred to Turbinellus, and thus to treat it separately, it is still formally within the genus Gomphus (where it doesn’t belong).

The taxon treated in this description is based on a concept of a montane/northern species that is more pallid than the red-capped coastal form in Western North America going by the name T. floccosus; it is likely that neither taxon is conspecific with T. floccosus sensu stricto (described from Pennsylvania). More work is needed to delimit species in this complex


Why suggested for a Global Red List Assessment?

Gomphus bonarii is widely distributed and very common throughout the higher elevation forests of the western United States. In many years, it is the most commonly encountered macro fungus in the Sierra Nevada and southern Cascade Range; no sign of decline has been noted. This fungus should be listed as Least Concern (LC).


Geographic range

Through most of the mountain ranges in California, USA; especially common in the Sierra Nevada and Cascade Range, continuing north on the east side of the Cascade Range into Washington. Possibly in the northern Rocky Mountains in eastern Washington, Idaho and Montana too.


Population and Trends

Widely distributed and very common throughout the higher elevations forests of the western United States. In many years, it is the most commonly encountered macro fungus in the Sierra Nevada and southern Cascade ranges (Siegel et al 2019). There is no sign of decline with this species.

Population Trend: Stable


Habitat and Ecology

Scattered or in clumps in needle duff and soil in mixed conifer forest. Ectomycorrhizal, presumably associating with both pines (Pinus spp.) and fir (Abies spp.). Primarily fruiting in fall, but also occasionally late spring or summer, in mid to high elevation forests.

Temperate Forest

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. Multi gene phylogenetic work is needed to delimit species concepts in the Turbinellus floccosus complex. Gomphus bonarii needs to be transferred to the genus Turbinellus.


Research needed

Multi gene phylogenetic work is needed to delimit species concepts in the Turbinellus floccosus complex. Gomphus bonarii needs to be transferred to the genus Turbinellus.
