Pileus 1-4.5 cm broad, obtuse to turbinate, sometimes broadly 

 convex to nearly plane in age or with the margin recurved slightly, 

 sometimes with a low obtuse umbo, the margin decurved, color evenly 

 "walnut brown" to "cinnamon brown," hygrophanous, fading to "fawn 

 color" or "avellaneous" and finally "cinnamon buff" to "vinaceous buff" 

 (dull deep rusty brown fading to avellaneous or buff), glabrous, 

 viscid and shining, with a thin separable pellicle, the margin translu- 

 cent striate when moist. Context concolorous with the surface, no color 

 change when bruised, thick under the disc, thin toward the margin, 

 fragile; odor and taste mild. 



Lamellae arcuate and soon distinctly decurrent, "avellaneous" to 

 "vinaceous buff" fading to "tilleul buff" (whitish) at times, close to 

 subdistant ( 20-26 reach the stipe ) , narrow to moderately broad, many 

 forking near their outer extremities, usually one tier of lamellulae, 

 edges entire. 



Stipe 3-6(8) cm long, 4-7 mm thick, white, equal or narrowed 

 toward the base, solid or with a narrow tubule, glabrous, not viscid, 

 apex merely silky and not pruinose. 



Spores 6-8 X 4.5-6 /*, ellipsoid, a few subovoid, smooth, yellowish 

 in Melzer's reagent. Basidia 37-51 X 6-8 /a, 4-spored, sterigmata 4-8 ^ 

 long. Pleurocystidia and cheilocystidia none. Gill trama intricately 

 interwoven, hyphae 5-8 ^ broad. Cuticle a gelatinous zone 40-70 /x 

 thick, hyphae repent, colorless, 3-4 fx broad — an ixocutis. Hypoder- 

 mium a conspicuous zone of brownish, radially parallel hyphae. Pileus 

 trama of interwoven hyphae. Clamp connections present on the 

 hyphae of the cuticle and gill trama.

 and beech woods, Michigan, Washington, and Ontario, Canada,
