Suillus pseudobrevipes  Smith & Thiers (1964)

This one is a somewhat rare Western species that has a similar short stalk as Suillus brevipes, but has a persistent annulus. The coloration of the cap though goes through more stages than the typical brevipes and is far more variable. Originally described from the montane regions under Lodgepole Pine (Pinus contorta), it seems to follow other Sullii in associating to to other Pine species with the same number of needles (2-needles in this case). Locally I see it abundantly in two patches under young Bishop pine (Pinus muricata).
