Assessment Notes

Taxonomic notes

Described from Washington, USA as Boletinus punctatipes (Snell & Dick 1941). Singer (1945) stated this species was a Suillus, but did not officially transfer it; Smith & Thiers (1964) made the transfer to Suillus.

Why suggested for a Global Red List Assessment?

Suillus punctatipes is a common Suillus in the Pacific Northwest, and rare to occasional in the California mountains.

Population is widespread in multiple forest types, and no sign of decline has been observed. I recommend listing as Least Concern (LC).

Geographic range

From scattered sites in the Sierra Nevada and Siskiyou mountains in California and southwest Oregon, becoming more widespread in the Pacific Northwest, where it occurs from coast through the Cascades, and with scattered sites into the northern Rocky Mountains to the east, and to southeast Alaska in the north.

Population and Trends

Population is widespread and appears stable; it can be locally abundant in the Pacific Northwest. No decline has been noted.

Population Trend: Stable

Habitat and Ecology

Ectomycorrhizal with Pinaceae in young to mature forests; especially Douglas-fir (Pseudotsuga menziesii), and with fir (Abies spp.) and hemlock (Tsuga spp.) in higher elevations. Fruiting in late summer and fall.
