Differs from the preceding, for which it is apt to be mistaken, in
the smaller apothecia and in the form of the more divided, smaller
spores. I t is evidently the plant primarily intended by Withering as
his Lichen tricolor, as appears not only from the specimens in his
own herb, but also from his diagnosis—“ saucers very minute,
orange-coloured, deeply hollowed, like the cup of a Peziza, the border
pale-brown.”
Hob. On the smooth trunks of trees, elm and ash, in wooded
upland tracts.—Distr. Local and scarce in England, N. Wales, the

colourless; spores 24-32nate, fusiform, 3-7-septate, 0,016-34

Externally somewhat similar to the two preceding species, but very
distinct in the number septation and form of the spores. In the
single British specimen gathered, which is only sparingly fertile, the
thallus is but little visible.

whitish, lacei’ate or crenate, a t length subobliterate ; hypothecium

In their earlier and more advanced stages of development, the
apothecia closely resemble those of G. exanthematica, near which the
species might almost be placed. The British specimens are well
fertile, with the apothecia occasionally submoderate in size.
Hab. On trunks of trees, chiefly elm, rarely ash, in maritime and
upland situations.—Bfsir. Only in S. England and the Channel
Islands, but plentiful where it occurs.—B. M. St. Brelade’s Bay

and near Ilfracombe, Devon; near Penzance, Cornwall.
9. G. cornea A. L. Sm.—Thallus effuse, very thin, granuloso-
pulverulent, whitish (K —, CaCl —), often evanescent. Apothecia
small, adnate, somewhat concave or suburceolate, reddish or
brownish flesh-coloured, the margin entire, smooth, paler ; hypothecium
colourless ; spores 8nate, elongato-acicular, raulti-(9-13-)
septate, 0,058—80 mm. long, 0,003—4 mm. th ic k ; hymenial
