Cortinarius seidliae Ammirati, Niskanen & Liimat. (2015)
Cortinarius seidliae is a relatively common species in the Pacific Northwest. It falls into Section Defibulati, along with Cortinarius vanduzerensis and C. mucifluus. Species in this section are medium to large with glutinous cap and stipe. Microscopy is important; they have large amygdaliform to citriform spores and no clamp connections (see: Index Fungorum Number IF551440). Often called C. vanduzerensis, (a species only confirmed from the type location on the Oregon Coast), C. seidliae is a recently described, widespread species in the Pacific Northwest, whereas C. vanduzerensis is apparently quite rare and likely range restricted. Additional species occur in California get lumped under the name C. seidliae/vanduzerensis as well.
Cap 40-75 mm wide, glutinous, light brown to cream at margin, darkening from olive-brown to brown with darkest tones on disc, margin wrinkled. Stipe 50-140 mm long and 7-14 mm at apex, clavate with rounded base, surface white, coated by a pale to dark violet glutinous sheath overall when young or lower half in more mature specimens. Gills very pale brown, darkening with age, Context white to cream in stipe apex, and yellow brown in base, sometimes hollow.
