SUBSECTION CAMAROPHYLLI 389 



longus, 10-15 mm crassus, solidus, subaequalis subfuscus, siccus, ghber; 

 sporae 6.5-8 X 4.5-5 ll, ellipsoideae. Specimen typicum prope Mil- 

 ford, Mich., Nov. 16, 1951, legit Ruth Dawson (Smith 60807), in Herb. 

 Univ. Mich, conservatum. 



Pileus 3-6 cm broad, turbinate, color dark gray to bluish-fuscous or 

 finally blackish brown ( "mummy brown" ) , surface glabrous and moist, 

 slightly viscid from a thin gelatinous pellicle, in age finally slightly 

 squamulose, margin at times rimose in age. Context gray to pallid; odor 

 of crushed flesh and the taste strong and resembling that of Clitocybe 

 nebularis (Fr.) Quel. 



Lamellae decurrent, whitish becoming cinereous, finally brownish 

 in age, thick, waxy, close, narrow to moderately broad, intervenose. 



Stipe 3-6 cm long, 10-15 mm thick, concolor with pileus above, 

 paler (pallid) at the base, equal to narrowed downward, surface dry, 

 glabrous, naked, solid. 



Spores 6.5-8 X 4.5-5 /z, ellipsoid, hyaline. Basidia 36-47 X 6-7 /x, 

 4-spored, flexuous, hyaline in KOH. Pleurocystidia and cheilocystidia 

 none. Gill trama of divergent hyphae. Pileus with a gelatinous epicutis 

 of appressed narrow hyphae. Clamp connections present. 



Habit, Habitat, and Distbibution — Scattered on low ground at 

 edge of a swamp in a beech-maple forest (no conifers near by, larch 

 50 yards away), Michigan, November. 



Matebial Studied — Michigan: Smith 60807 (type, from Proud 

 Lake Recreation Area, near Milford, collected bv Ruth Dawson, Nov. 

 16, 1958). 



Obsebvations — This species is obviously a segregate of Hygropho- 

 rus camarophyllus, but we have never found the latter to have the 

 odor and taste of Clitocybe nebularis and to grow under hardwoods.
