This anomalous plant resembles O. cariosa, hut beside other characters
differs in tbe absence of any tlialline reaction. I t is near C. pyxidata ;
but the form of tbe thallus and of the podetia (which when dry become
shrunken and somewhat costate) entitle it to rank as a species ; it was so
regarded by tbe older authors, and more recently by Nylander (‘Flora,’
1874, p. 70). The apothecia are nearly hemispherical, and much broader
than the podetia.

Resembling generally C. fimhriata and var. chlorophæa of C.pyxidata, yet
so constant as to deserve to rank as a proper species. I t is distinguished
by the furfuraceo-pulverulent podetia and the minutely fimbriate narrow
scyplii, which are pervious or non-pervious. The apotliecia are small and
marginal on the scyphi, or large and subpedicellate, becoming dark in old
age.

This differs in the minutely squamuloso-furfuraeeous podetia somewhat
elongate when sterile. Though distinct, it is only a form, as in the type
a few miuute squamules are occasionally present. In the only British
specimen the apothecia are somewhat numerous.

Till recently this was regarded by authors as a variety of C. pityrea.
In addition, however, to the more elongate, subulate, apically acute
podetia, with their terminal apothecia, it is at once separated by the
thalline reaction with K. Of tbe two specimens gathered in this country,
one is fertile.

From the two preceding species this is distinguished by the scyphi and
by the reaction with K. In the few British specimens the podetia are
rather short (about in. long), occasionally somewhat fasciculate, with
