Stromata gregarious, up to 1 mm. diam., rather flat, but 
projecting by a broadly conical cre subunilocular or plurilo- 
cular, the loculi arranged round a central black columella. Spores 
5-6 X 1-1°5 uw; sporophores filiform, simple, up to 25 w long. 
On dead bark of branches of Sambucus nigra, causing small 
round dark swellings. Wirksworth, Derbyshire (Gibbs). Oct. 
Diedicke describes it as “ on elongated bleached patches of 
the periderm,” but there cannot be any doubt that these speci- 
mens are the same species as those described by Miss Smith.
