Pileus convex, becoming nearly plane, sometimes nmbonate, 

 glabrous or obscurely radiately fibrillose or fibrillose-squamose 

 with innate or appressed fibrils, ochraceous-buff when dry; la- 

 mellae moderately close, blackish-brown when mature ; stems 

 long, slender, glabrous, solid, slightly thickened at the base,

Described from specimens collected on the ground at Yakutat
