BURT THELEPHORACEAE OF NORTH AMERICA. XV 273 



Manitoba: Winnipeg: A. H. R. Buller, 744 (in Mo. Bot. Gard. 

 Herb., 57913). 



82. C. jamaicense Burt, n. sp. 

 Type: in Burt Herb. 



Fructifications broadly effused, adnate, thick, somewhat mem- 

 branaceous, small pieces separable when moistened, becoming 

 buff-brown to tawny olive in the herbarium, even, pulverulent, 

 not cracked, the margin probably thick and entire but not well 

 shown by the fragments; in section 150-600 \l thick, concolorous 

 with the hymenium, composed of even, suberect hyphae 3 (i in 

 diameter, of interwoven organs 2 [l in diameter with antler- 

 shaped branching, of colored gloeocystidia, and of imbedded, 

 globose, slightly colored, rough-walled spores 6-7 \l in diameter, 

 very numerous in all regions; gloeocystidia becoming dark-colored, 

 irregular, flexuous, 35-60 X 5-7 (x, scattered throughout the 

 fructifications, none found protruding; basidia simple, with 4 

 sterigmata; basidiospores spherical, hyaline, even, 6 \l in di- 

 ameter as seen attached to basidia. 



Fructifications received in fragments, of which the largest is 7 

 cm. long, 2 cm. wide. 



On decaying wood. Jamaica. December to January. 



The general aspect and antler-shaped branching of one kind of 

 its hyphal components show relationship to Hypochnus penio- 

 phoroides, H. pallescens, Stereum induratum, S. duriusculum, As- 

 ter ostromella dura, and A. rhodospora. Could I have found un- 

 even basidiospores this species would have been included in 

 Hypochnus near H. pallescens and H. peniophoroides; such basidio- 

 spores may eventually be demonstrated when this species be- 

 comes better known.
