72. C. pilosum Burt, n. sp. 



Type: in Mo. Bot. Gard. Herb. 



Fructifications effused, becoming confluent, closely adnate, 

 very thin, not separable, pale pinkish buff, becoming pale olive- 

 buff and pale smoke-gray in the herbarium, even, not shining, but 

 little or not at all cracked, the margin of the same color, thinning 

 out; in section 30-75 y. thick, not colored, composed of densely 

 interwoven, hyaline hyphae 2-23^ y. in diameter, not incrusted, 

 of gloeocystidia, and of delicate, branching paraphyses; gloeo- 

 cystidia near the substratum, spherical or pyriform, 16-30 pL in 

 diameter or up to 30 X 15 \l, narrower gloeocystidia may be 

 present also ; paraphyses with slender branching tips about 1 (i in 

 diameter occur in the surface of the hymenium; spores hyaline, 

 even, curved, 6-9 X 3-4J/2 \l. 



Fructifications becoming confluent over areas up to 8 cm. long 

 and 1-2 cm. wide. 



On bark of fallen limbs of Alnus, Vitis, and Tsuga. Georgia, 

 Alabama and Missouri. October and April. Not common. 



C. pilosum has general aspect and color suggestive of the Penio- 

 phora cinerea group of species but has no cystidia. The slender 

 branching paraphyses have been noted also in Peniophora phyl- 

 lophila, C. albido-carneum, C. Aikinsonii, and C. jamaicense. 

 Perhaps C. pilosum is mature C, albido-carneum.
