Pileus 8-25(30) mm broad, obtuse, expanding to broadly convex 

 or nearly plane, glabrous, "benzo brown" ( purple drab ) , fading to pale 

 vinaceous drab when dried avellaneous to dingy pinkish buff. Context 

 thin, whitish; taste mild, odor none.

 (lilac gray), distant, edges even. 



Stipe 1-3 cm long, 2.5-5 mm at apex, narrowed downward, pallid, 

 naked, dry, no veil. 



Spores 7-8(10) X 4.5-5.5 /x, ellipsoid, smooth, pale yellow in 

 Melzer's reagent. Basidia 41-55 X (5)6-8 /*, 2- and 4-spored. Pleuro- 

 cystidia and cheilocystidia none or the latter present as a few hairs 

 18-30 X 2-3 jx. Gill trama interwoven, hyphae 6-9 /x broad. Cuticle of 

 repent hyphae, a few hyphae appearing slightly gelatinous. Clamp 

 connections present on the cuticular hyphae. 



Habit, Habitat, and Distribution — On soil, on a stream bank, 

 Washington, Mt. Rainier National Park, September; also Europe. 



Material Studied — Washington: Smith 48072. 



Observations — It differs from H. subviolaceus and H. pallidus in 

 its larger spores and mild taste; from H. lacmus in its lack of a yellow 

 stipe-base; from H. uliginosus in its pileus color and lack of a striate 

 pileus,
