The apothecia in both type and variety are extremely minute and
look as if seated on small pale cushions of the thallns, though in the
variety the thalline growth tends to disappear.

Characterized by the bright prominent sometimes almost
spherical apothecia which have caused it to be confused with
Bilimbia sphoeroides, Koerb. The apothecia are numerous and vary
in size, at tunes they are crowded and rather small.

wooded situations.—EisZr. Scarce in E n g lan d ; more frequent in the
S. Highlands of Scotland, and in N.W. Ireland.—E. M. Hatfield-

Differs from the preceding in the more distmct thallus and in the
plane apothecia.

A singular plant which might readily be taken for a biatorine state
of a species allied to Lecanora varia, of which Schærer (Enum. p. 82)
considered it a variety. A very marked character is afforded by
the numerous large spermogones, which were formerly regarded as
foreign parasitical bodies or, in sterile specimens, as abortive
apothecia. They are superficial, black, usually crowded, warted and
corrugate (K-prose-violet), beneath colourless, with short, simple
sterigmata and oblong spermatia, 0 ,0 0 2 -3 mm. long, 0,001 mm. thick.
