Sarcodonimbricatus – hawk-wing, scaly hedgehog, shingled hedgehog, scaly tooth Distribution: Broad Habitat: S. imbricatus is commonly found in the conifer forests of the PNW and in either conifer or mixed forests in the rest of North America and much of Europe.
Sarcodonscabrosus – bitter hedgehog, scaber Hydnum, bitter tooth Distribution: Common in PNW Habitat: S. scabrosus occurs in conifer forests in the PNW, especially in second-growth stands of western hemlock and Douglas-fir with a salal understory.
Sarcoporiapolysproa Description: Annual. Resupinate, or reflexed or sessile. Cap when present is white to light brown, drying reddish brown. Hymenium white drying reddish brown. Pores round. Distribution: North America Habitat: Forested areas. Substrate: Found on both conifers and hardwoods.
Sarcosphaeracoronaria – pink crown, violet crowncup, violet star cup, crown fungus Distribution: S. coronaria occurs in spring, mostly in the mountains, often near melting snow, and is a harbinger of morel season. It also occurs in Europe and has been called S. crassa (Santi) Pouzar and S. eximia (Durieu & Léveillé) Maire. Spores: The spores are broadly ellipsoid (13--22 x 7--10 µm) with blunt ends and usually two large oil drops.
Stereopsishumphreyi Distribution: As far as we are aware, S. humphreyi has been reported only from the west side of the Olympic Peninsula in Washington and the Queen Charlotte Islands in B.C. It probably also occurs in southeast Alaska and coastal Oregon and northern California; whether it occurs farther inland is less certain.
Strophariahornemannii – luxuriant ringstalk, conifer roundhead, lacerated Stropharia Distribution: It is widespread in the north temperate and boreal forests of the Northern Hemisphere Habitat: It sometimes occurs on intact conifer logs, but is most abundant on wood that has been more highly decomposed.
Suillustomentosus – woolly pine bolete, blue-staining slippery jack, poor man's slippery jack, tomentose Suillus, woolly-capped Suillus, woollycap Distribution: Very common and abundant in the PNW. Habitat: S. tomentosus occurs primarily under lodgepole and shore pines.
Suillusumbonatus – jellied bolete, slim jack, umbonate slippery jack Distribution: It is broadly distributed in the Northern Hemisphere. Habitat: It is rather abundant at times in lodgepole pine forests in late summer and early fall, and in shore pine woodlands in fall, sometimes growing in clusters and lining the edges of moist depressions.
