(K —, CaCl —). Apothecia minute, adnate, the dise brownish 
or blackish, at first plane and then with a thin rather paler 
margin, becoming convex and immarginate; paraphyses some- 
what conglutinate, slightly thicker, knobbed and brown at the 
tips, and often shortly branched and septate ; spores 12-24 in 
the ascus, oblong-ellipsoid, straight or slightly curved, 13-16 p 
long, 5-8 p thick.—R. sophodes Massal. Ric. Lich. Crost. p. 14

Distinguished by the number of spores in the ascus. There is no 
British specimen in the herbarium. 
Hab. On smooth bark of trees in mountainous regions.—Distr. 
Only very sparingly at Craig Calliach, Perthshire.

entire, sometimes becoming crenulate ; spores ellipsoid, 12—20 p

The thallus, though mostly circumscribed by the black line of 
the hypothallus, is sometimes effuse, and generally crowded with 
apothecia. These owe the dark colour of the disc to the paraphyses, 
which are brown over the tips; they are slightly wider and septate 
upwards, sometimes ending in several short branchlets. The spores 
have thickened walls, each cell with a restricted lumen, which shows 
frequently a projection towards the median septum. Massalongo’s 
species has asci 14~-20-spored, and evidently refers to R. polyspora. 
Hab. On trunks of trees, especially ash, in wooded localities. 
Distr. Local and rare in S.W. and N. England and S$. Wales.—

Forest, Hants; near Cuckmere, Sussex; Kemble, Wilts; Llanymy-

Yorkshire.
