BURT THELEPHORACEAE OF NORTH AMERICA. XV 217 



Type : type distribution in Ravenel, Fungi Car. 3 : 29. 



Fructifications broadly effused, ceraceous-fleshy, drying mem- 

 branaceous, small pieces separable when moistened, becoming 

 cinnamon-buff to army-brown in the herbarium, even, shining, 

 not cracking, the margin paler, narrow, with hyphae interwoven ; 

 in structure 100-400 y. thick, not colored, composed of erect, 

 densely interwoven, agglutinate, thick- walled hyphae 2^-3 ii in 

 diameter, not incrusted, rarely, if at all, nodose-septate; no 

 gloeocystidia ; spores hyaline, even, flattened on one side, 10-16 



Fructifications 1-10 cm. long, 1-3 cm. wide; sometimes con- 

 fluent over areas up to 1 m. long. 



On decaying trunks of frondose species. New Jersey to Mexico, 

 in the West Indies, and in South Africa. Throughout the year. 

 Uncommon. 



C. ceraceum varies in the thickness of its fructifications which 

 are usually cinnamon to ochraceous-orange in color and some- 

 times become very large. The spores are so very large that they 

 afford a good distinctive character but are most likely to be 

 found in crushed preparations of the hymenium.
