Josserand ( 1959) reports clamp connections. We have Found them 

 to be very rare.

Hygrophorus unguinosus var. subaromaticus Sin. c\ Hes. 



Lloydia5: 81. 1942 



Pileus 2-5 cm broad, convex with an incurved margin, becoming 

 plane or nearly so, color "huffy brown" on the disc, "pale olive-buff' 

 near the whitish margin (a dull olive grayish brown to pallid), gla- 

 brous, slimy-viscid, margin striatulate. Context thin, very soft and 



fragile, whitish; odor faint but disagreeably subaromatic, taste mild to 

 slightly disagreeable. 



Lamellae bluntly adnate with decurrent tooth, white with a faint 

 gray cast, broad, subdistant, edges even. 



Stipe 5-6 cm long, 6-10 mm thick, concolorous with the gills when 

 fresh but drying pale gray like the pileus, equal, hollow, fragile, 

 slimy-viscid as in H. laetus, glabrous. 



Spores 7-9 X 4-5.5 /a, ellipsoid, smooth, pale yellow in Mel/.er s 

 reagent. Basidia 42-55 X 7-9 /x, 2- and 4-spored. Pleurocystidia and 

 cheilocystidia not differentiated. Gill trama subparallel, hyphae 7-14 n 

 broad, yellow in Melzer's reagent. Cuticle a thick (180-300 /x), 

 gelatinous zone, the hyphae narrow, colorless, more or less interwoven 

 (an ixotrichodermium). Hypodermium a rather well-defined brownish 

 zone. Pileus trama of radial hyphae. ('lamp connections absent or very 

 rare. 



Habit, Habitat, and Distbibution — On soil under redwoods, 

 California, November. 



Matebial Studied — califobnia: Smith 9167 (tvpe, from Prairie 

 Creek State Park, Orick, Nov. 28, 1937). 



Obsebvatioxs — The faint but disagreeably subaromatic odor 

 and almost complete lack of clamps on the hyphae distinguish tin's 

 variety from the type.
