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 macrofungus in the Sierra Nevada and southern Cascade Range. No sign of decline has been reported and no threats have been identified. This fungus is assessed as Least Concern (LC).
Taxonomic notes
It was described as
Cantharellus bonarii (Morse 1930), then transferred to the genus
Gomphus (Singer 1945). Phylogenetic studies (Giachini 2004, Giachini and 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 and 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.
Geographic range
It is found through most of the mountain ranges in California, USA; being especially common in the Sierra Nevada and Cascade Range, continuing north on the east side of the Cascade Range into Washington. It possibly also occurs in the northern Rocky Mountains in eastern Washington, Idaho and Montana.
Population and Trends
It 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 macrofungus in the Sierra Nevada and southern Cascade ranges (Siegel et al. 2019). There is no sign of decline in this species.
Population Trend: stable
Habitat and Ecology
It can be found scattered or in clumps in needle duff and soil in mixed conifer forest. It is ectomycorrhizal, presumably associating with both pines (
Pinus spp.) and fir (
Abies spp.). Fruiting most often occurs in fall, but it may also occasionally occur in late spring or summer in mid to high elevation forests.
Threats
No specific threats have been identified with regards to this species.
Conservation Actions
No specific conservation actions are needed with regards to this species. Multi-gene phylogenetic work is needed to delimit species concepts in the
Turbinellus floccosus complex, and
Gomphus bonarii should eventually be transferred to the genus
Turbinellus.
