BRITISH DISCOMYCETES. 
oblong, or oblong-elliptic, with 3 guttulae, at length 3-septate, 
15-17 X 5-7 n ; paraphyses clavate at the summits. 
On bark of Acer Pseudoplatanus. October. 
The cups are j to | a line broad, rarely single, erumpent, and 
remarkable from their hoary- whiteness. Nearer D. livida (B. & 
Br.) than any other species. It is not Nodularia acericola 
(Peck.), which is also a Dermatea , and which has much larger 
sporidia. 
I am indebted to Mr. W. B. Grove, of Birmingham, for this 
interesting species.
