Plants single, gregarious, never cespitose (rarely two to- 

 gether), up to 6.3^ cm. tall, distinctly stalked, compressed and 

 channelled, at times quite simple, but usually cusped or antlered 

 or palmately branched or variously lobed, much in the fashion of 

 the Krombholzii or rugosa form of C. cristata, or at times even 

 more branched like C. muscoides; the tips blunt or pointed and 

 blackening in age ; club when simple tapering downward from the 

 broadened end, 3-6 mm. thick ; when branched up to 3.6 cm. broad; 

 the distinct stalk 0.6-3.5 cm. long, the sterile part (or true stalk) 

 up to 2.6 cm. long to the descending hymenium, about 0.7-2.2 mm. 

 thick, nearly glabrous except for the velvety tomentose base, the 

 stem and usually the club somewhat crooked ; color of hymenium 

 a pale livid flesh color (about fleshy tan or pale drab) at times ap- 

 proaching fawn (in the type said to be very pale lilac), the stem 

 a little darker and more watery-looking; flesh solid and color of 

 surface in all parts, soft and rather waxy-brittle in the club, tough 

 and pliable in the stem ; taste slight, mildly flattish alkaline, odor 

 none. 



Spores (of Hartsville, No. 42) pure white, plentiful, smooth, 

 almost filled with a slightly eroded sphere, subspherical, 5.9-7.5 

 x7.5-8.5ji.. Basidia (of No. 4532) 7-9.7 x22f/, with two sterig- 

 mata. Hymenial layer 37-130{/. thick, proliferating irregularly 

 and containing embedded spores. Hyphae of flesh loosely packed, 

 about % in diameter with many septa and a few clamp connections. 



The stem may be distinguished from the hymenium with the 

 naked eye by a slight or decided difference in color, and under a 

 lens by different surface texture. The plant has the spores and
