minute glaucous squamules, slightly pervious at the axils and lacero-

Differs perhaps as a subspecies in the colour of the podetia and the 
form of their apices. In our only two British specimens the podetia are 
almost entirely furfuraceous, with a few scattered squamules towards 
the base. The apothecia, which are small, dark-brown, are very rarely 
present.

25. C. scabriuscula Nyl. Flora, 1876, p. 447.—Thallus squa- 
mulose at the base, the squamules small, often evanescent ; podetia 
cespitose, slender, erect or curved, scabrid, more or less minutely 
squamulose, divaricately branched, greyish-white, the branches 
subalternate, recurved and furcate at the apices (K-+yellowish, 
CaCl—). Apothecia moderate, terminal, brown.—Cromb. Journ. 
Bot. 1876, p. 360; Leight. Lich. Fl. ed. 3, p. 61.—Cenomyce 
scabriuscula Del. in Dub. Bot. Gall. ii, (1830) p. 623. 
This approaches on the one hand subsp. C. racemosa f. recurva (tenwior) 
and on the other subsp. C. adspersa of the following species. From 
both, however, it is separated by the podetia and the reaction with K, 
so that it may with pene be regarded as holding an intermediate 
specific place. In our British specimens there are only a few young 
apothecia. 
Hab. On mossy rocks and old walls in maritime and upland districts.
