sporidia 8, elliptic, 8 x 34; paraphyses filiform.

dolleana—Fckl., “Symb. Myco.,” p. 330. 
Exs.—Fcekl, “ F. Rh.,” No, 2195. 
From Sclerotium pustula on leaves of Castanea. 
Cup 8 lines broad; stem about linch long. It grows 
separately or in little fascicles of three or four; the stem 
is slender, filiform, naked, of rather a firm consistence, 
and of a deep red colour; sometimes the lower part has 
white hairs, but they evidently depend on excess of 
moisture. It is at first only a simple thread, straight or 
crooked; later on the summit swells—it then resembles 
a little pin; finally, it forms a small flat cup, reddish, 
with a thin, regular margin, sometimes entirely expanded, 
and even decurved. The hymenium is a little less 
coloured than the cup, and composed of very small asci, 
which enclose eight elliptic, simple, transparent sporidia ; 
no paraphyses were seen. It is most closely related to 
Pezvza subulipes (Bulliard), having the same colour, but 
es which it differs by its habitat, size, and form of cup 
(Lev.). 
Name—After A. P. de Candolle.
