There lias been considerable difficulty about this plant, owing to the
variable character of the spores, which, as already observed, has led to its
being confounded with the preceding. The thallus is so thin as to be
scarcely distinguishable from the bark upon which it grows, and is usually
evanescent or none proper. The apothecia are generally numerous, sometimes
2-3 congregate, with the stipites varying in length from to
I inch, and occasionally, when more elongate,' becoming branched.

Closely allied to the two preceding species, but smaller and more
slender, with the apothecia very much scattered and the spores smaller.
Unless after a shower of rain, it is scarcely visible, and is consequently
overlooked. The apothecia are frequently branched, becoming occasionally
somewhat fasciculate.

Cherb. iii. (1856) p. 168.—Thallus effuse, leprose, th in , or scarcely
any d is tin c t; gonidial lay e r consisting of gonidimia, various in
form. Apotheoia stipitate, globoso-pulverulent, yellow or pale,
stipes usually e lo n g a te ; sporal mass copiously accumulated on the

mixed with th e paraphyses; spermogonia with simplish sterigmata,
and oblong or ellipsoid spermatia.
In the type of the apothecia this has the same relation to Calicium that
Biatora has to Hulecidea. I t differs from Calicium in the pulverulent
globo.se capitulum and in the constantly spherical form of the spores,
although, as already observed, it closely approaches subgen. Allodium.

The thallus, which is more or less effuse, and internally has oblongo-
cjlindrical gonidimia, occasionally becomes nearly evanescent. The stipites
are very weak, and consequently more or less flexuose; while in
old age they are denudate and become brown or blackish The apothecia
when present (for the thallus is very frequently infertile) are numerous,
scattered, or crowded. Our fig. (h) shows the brown axis of the stipes
ascending into the cupula, left white in the figure, and the pale brownish
pulvinate subcoliimelliform hypothecium. The spermogones are apt to
be overlooked, being nearly concolorous with the thallus.
Hah. On the roots of decayed trees and on dead twigs, occasionally on
the ground and decayed mosses, rarely on rocks in shady upland places. —
