BURT — THELEPHORACEAE OF NORTH AMERICA. XV 339 



Fructifications probably large, for specimen received is 9 cm. 

 long, about 1 cm. wide, and broken ofT on all sides. 



On decorticated, rotten, frondose log. South Africa. January. 



S. africana resembles in aspect Corticium ochraceum but is a 

 Sebacina in structure. It is further distinguished by its buff 

 color, sparingly granule-incrusted, gelatinous-walled hyphae, 

 small spores, and colorless, flexuous gloeocystidia which are in all 

 respects like those present in some species of Corticium and 

 Peniophora. The gloeocystidia locate S. africana in the sub- 

 genus Bourdotia of Sebacina.
