1920] The Lower Basidiomycetes of North Carolina 133 



The smaller, single pustules are about 3 mm. wide and 2 mm. high, 

 the longer, compound ones may reach a height of over a cm. and 

 extend in more or less interrupted rows for a foot or more along the 

 branches. This plant differs from Exidia gelatinosa in darker color, 

 smaller size and pulvinate form which is quite unlike the thin, flat- 

 tened, laterally attached caps of the latter. It also differs in the 

 black papillae on the h^anenial surface and the absence of the close-set, 

 dark, inherent dots on the dorsal surface. Very common on 

 many kinds of deciduous trees and shrubs, as on privet, 

 osage orange, Baccharis and others, besides those mentioned below. 

 Individual pustules are often without papillae, and such are probably 

 E. epapillata Bref. and Tremella intumescens Sm. Brefeld gives the 

 spores of the European E. glandulosa as 5 x 14[x which is a little larger 

 than in ours. Exidia pUcata Klotzsch seems to be another European 

 form on alder with few papillae and slightly longer spores, up to 20/;..

The following is by Mr. C. G. Lloyd : 



"Sessile, cushion shape, gyrose, lobed. Color of a raisin. Flesh 

 same color. Papillae none. Basidia globose, 8-10/^, very pale color. 

 Spores hyaline, 5 x lOfx, slightly curved, unilateral, apiculate. 



"Were we to determine this from books we should call it Exidia 

 saccharina, but we know this in Europe and it is not that species. 

 The color miglit be compared to brown sugar but better to a raisin. 

 We do not find it in Ridgway, but pecan brown is not far away. 

 Whik^ it lias no papillae we put it in Exidia on the spores. As 

 previously stated the line between Tremella and Exidia is hard to 

 draw. In general appearance this is rather a Tremella. The color 

 is somewhat like that of Naematelia nucleata when old. It dried 

 away leaving hardly a trace on the bark. It grew on frondose wood.
