Characterized by the form of the squamules. In our specimens, 
asci and spores are sparingly present; the latter do not measure more 
than 3-4 » in length.

Minute portions of the thallus are occasionally visible round the 
apothecia, which, as in the species, may be pruinose or naked (ff. prwini- 
fera and denudata). It is closely related, if not identical, with var. 
conspersa Th. Fr. Lich. Arct. p. 88 (1860), but the descriptions do not 
entirely agree.
