Collection location: Motase Peak (near Shelagyote Peak), B.C.

Remarks: on ground near Abies lasiocarpa (Hooker) Nuttall; field collection 73; cap slightly conic, silky, pale cinnamon brown; gills cinnamon; stem beige with cinnamon brown; Ammirati says "Cortinarius, section Laeti – Your field collection 73 Kare listed under C. auchmerus Moser, this is a synonym of C. laetus Moser. C. detonsus (Fr.:Fr.) Fr., your field collection 78, is a similar to laetus morphologically, however, it has basidiospores 9-10 x 5-6.5, ellipsoid to broadly ellipsoid, slightly verrucose to nearly smooth, while the basidiospores of C. laetus are 10-12.5 (-14) x 5.2-6.8 µm, somewhat more verrucose and amygdalioform. Your field collections 73 and 78 both have relatively large spores, here it would be a good idea to sequence additional material and compare these two taxa."
