Though regarded by authors as belonging to C.fuyeala, var. recurva of
wliich It closely approaches, Nylander now refers this to C. squamosa as
a subspecies well characterized by the podetia. With us, as elsewhere,
the apothecia are very rare, but the spermogones are frequent.

From subspecies C. adspersa, which it closely resembles, this diffe,rs in
the erect podetia and their fasciculate branclie.s, which are subulate or
truncate at the apices. I t may thus with propriety be regarded as a
distinct species rather than as a subspecies of C. squamosa. In tlie very
few British specimens the podetia, wliich are 2 -3 | in. long, are sparingly
foliiferous throughout, wdtli the apothecia rarely pre.sent.
