Found some of these on both sides of the Ca./Ore. border growing under Sitka spruce.
Had difficulty getting spores to drop from all the collections. Spore measurements were from sparse whitish spore print and were ~ 9.5-13.2 X 5.9-8.0 microns.
They were rather variable in size and on average larger than stated in the references for this species(9-12 X 5-6 microns).
Hesler and Smith do note a couple of varieties of this species, one of which has been found in Oregon and Washinton; Hygrophorus olivaceoarbus var. gracilis. However, the cap is described as “…virgate with dark-cinereous fibrils beneath the gluten, disc blackish, margin sordid olivaceous-cinereous.” Apparently this species is usually small, caps 1.5-3cm broad.
