1920] The Lower Basidiomycetes of North Carolina 129 



The minute size and obscure color render the plant almost invis- 

 ible in passing. The plant seems to agree well with 8. Brefeldianum 

 of South Brazil (see Moller) and adds a genus to the North American 

 flora. Two other species, S. albidum Lag. & Pat. and 8. sanguineuiti 

 Lag. & Pat., have the basidia divided into four cells by longitudinal 

 or slightly oblique septa. They are both from Eequador (see Jour. 

 Bot. 6:465. 1892).

TREMELLACEAE 



Plants growing on wood, more or less gelatinous and translucent, 

 toughish or soft, shrinking and becoming hard on drying, sometimes 

 shelving and irregularly cup-shaped or ear-like, more often irregularly 

 folded and lobed or brain-like or forming simple cushions; in another 

 group thin, tough and leathery or coriaceous, and encrusting wood 

 as in the Corticiums; in one genus (Tremellodon) with an eccentric 

 cap and teeth like a Hydnum on the under surface. Hymenium cov- 

 ering all the exposed surface of the body (as in Tremella) or only the 

 lower surface (as in Tremellodon). Basidia spherical or ovate or 

 pear-shaped, divided into four cells by longitudinal or oblique walls. 

 Basidiospores smooth, subglobosc, pip-shaped, broadly elliptic, or 

 elongated and curved : color various. Not yet reported from America 

 are the genera Protodoiitid and Proioli!/(hn(in (See Trans. Brit. ]\Iyc. 

 Soc. 6:69. 1917).
