BURT THELEPHORACEAE OF NORTH AMERICA. XV 313 



Fructifications gregarious or cespitose; pileus thin, coriaceous- 

 fleshy, depressed or subinfundibuliform, sometimes split on one 

 side, slightly floccose-squamulose or fibrillose, grayish or grayish 

 brown, becoming light drab in the herbarium, wavy or lobed on 

 the margin, the lobes often overlapping; stem equal, solid, colored 

 like the pileus; hymenium uneven or shallowly radiately venose, 

 decurrent, drying light pinkish cinnamon; no setae nor cystidia; 

 basidia with 4 sterigmata; spores hyaline, even, flattened on one 

 side, 6-9 X 4^-6 pu 



Fructifications when dried lJ^-2 cm. high; pileus 4-13 mm. in 

 diameter; stem 8-14 mm. long, 1-1}^ nun. thick. 



On ground under trees of Fagus. New York and Delaware. 

 July and August. 



Peck noted this species as related to C. sinuosus, from which it 

 differs in smaller size, solid and darker-colored stem, and slightly 

 smaller spores. The fructifications are apparently plentiful when 

 found, for some 30 fructifications of various sizes comprise each 

 gathering.
