Fructifications solitary or cespitose, gelatinous, rather tough, 
erect, white, repeatedly lobed or forked, with the peripheral 
lobes thin, flat, much crinkled or fluted, drying with the upper 
portion white and basal portion ochraceous tawny; basidia 
subglobose, 7-10 x6-7L4 w; spores hyaline, even, 5-6 x4-4l5 u, 
as found in a preparation of the hymenium. 
Mass of fructifications about 2 em. high and 3-5 cm. in di- 
ameter in northern specimens, attaining larger size in Brazil. 
On dead wood. North Carolina, West Indies, and Brazil. 
October to January. 
Tremella fuciformis occurs on wood in a rosette-like mass of 
thin, crinkled, and fluted lobes, white and drying white except 
in the region of attachment to the wood where the color is 
ochraceous tawny; the basidia and spores are subglobose and 
small.
