BURT THELEPHORACEAE OF NORTH AMERICA. V 745 



Bot. 1:238. 1849. — Stereum Leveillianum Berk. & Curtis, 

 Grevillea 1 : 163. 1873. 



Type : type and cotype in Kew Herb, and in Curtis Herb., 

 respectively. 



Fructification coriaceous, soft, dry, rather thick, vinaceous 

 fawn at first, whitening with age, resupinate-effused, with the 

 margin free, sometimes narrowly reflexed, concolorous, 

 minutely tomentose; hymenium composed of a surface layer 

 about 30 n thick of paraphyses 1^-2 /* in diameter and of a 

 layer of basidia under this; basidia longitudinally septate, 

 10-18 X 6-12 /*; spores in spore collection, white, simple, 

 curved, pointed at base, 12-16 X 5-6 /*. 



Fructifications often 5 mm. in diameter at first, finally up 

 to 1-5 cm. long, £-1$ cm. broad, about \ mm. thick. 



On dead limbs of several species. New York to Texas, 

 Cuba, Jamaica, Central America, and Brazil. November to 



May. 



This is a well-marked species upon which Berkeley made the 

 following excellent graphic comment : 



"At first forming little peltate orbicular spots, which, as 

 they dilate, become closely attached to the matrix, with the 

 exception of the margin, which is often free, soon confluent, 

 soft, rather thick; of the colour of raspberries and cream. 

 Hymenium often minutely pitted. Old specimens lose in great 

 measure their ruddy hue, and are of a dead white." 



I have seen no specimens having the hymenium minutely 



pitted.
