368 SECTIOX HYGROPHORUS 



cheilocvstidia none. Gill trama of divergent hyphae. Epicutis of pileus 

 a tangled trichodermium of short, narrow filaments ( 1-2.5 /x wide ) 

 dingy yellowish as revived in KOH. Clamp connections present. 



Habit, Habitat, and Distbibution — Gregarious under white cedar 

 and spruce. Wilderness State Park, Emmet County, Mich., Oct. 15, 

 1960. 



Matebial Studied — Michigan: Smith 63330. 



Obsebvations — The dry stipe often changing to yellow at the 

 base, and spotting yellow in KOH, the dingy color and lack of an odor 

 and taste are distinctive. It is related to H. avellaneifolius, but is not as 

 soft and the gills are paler and dry paler.

Illustration: 

 Fig. 118. 



Pileus 1-3(4) cm broad, convex with an incurved margin, expand- 

 ing to plane or nearly so, margin at times elevated in age, color avel- 

 laneous to dingy pinkish buff over disc, cinereous pallid over margin, in 

 age a cinereous shade often pervading the entire cap, surface glabrous 

 and viscid. Context thick but very soft, pallid to slightly cinereous; odor 

 and taste not distinctive. 



Lamellae adnate becoming decurrent, "avellaneous" or somewhat 

 paler or darker, close to subdistant, moderately broad, edges even. 



Stipe 3-5 cm long, 3-8 mm thick, more or less concolorous with the 

 gills, equal, solid, soft, dry, densely pruinose above and at times over 

 all except the mycelioid base. Veil none. 



Spores 6.5-8 X 4.5-5 /x, oblong to ellipsoid, smooth, hyaline, yellow- 

 ish in Melzer's solution. Basidia 42-50 X 6-8 /x, 2- and 4-spored. Pleuro- 

 cystidia and cheilocystidia none. Gill trama divergent, hyphae 5-8 /x 

 broad. Cuticle a well-defined gelatinous zone, 80-130 /x thick, with 

 narrow (3-6 /x), loosely tangled hyphae. No hypodermium differen- 

 tiated. Pileus trama interwoven, the hyphae radially disposed. Clamp 

 connections present. 



Habit, Habitat, and Distbibution — Gregarious under conifers, 

 Michigan, October. 



Matebial Studied — Michigan: Smith 43736 (type, Point Aux 

 Chenes, Oct. 4, 1953). 



Obsebvations — The densely pruinose dry stipe, avellaneous gills 

 which become cinereous like the pileus in dried material, small spores,
