From the preceding this is distinguished by its different babit, tbe
colour oi the more corticate podetia, and the 'incmved m.argin of tbe
scyphi. I t is often somewhat macrophyllous at the hase. The podetia
which are 1-2 in. long, not unfiequeutîy arise from the margins or the
surface of the leaflets, and are either naked or with a few smaller and
scattered leaflets chiefly towards the base or at the apices. In sterile
specimens they are often cornute or subulate. AA'ith us the apothecia
are rare.

Differs in the more developed basal thallus and in tbe slender, narrow
usually substerile podetia. Our British specimens are only sparingl-y
spermogoniiferous. ^ ^

narrow.—Cromh. Grevillea, xv. p. 46. — Cenomyce diejitata o. cerucha
Ach. Syn. (1814) p. 208.
The more turgid and almost cornute podetia and the very small
narrow scyphi distinguish this form from the type. I t is very rarely seen
with the apothecia well developed, but occurs for the most part in a
sperniogODiifei-ous or substerile condition.

Evidently but an accidental moQstro.sity, characterized by tbe more
turgid pode’tia and the abnormal form of the scyphi. In the few British
gpeciineus the apotliecia are but sparingly present.

In its typical state this is distinguisbed from the preceding by the
smaller basal squamules, wliich are esorediate beneath, and by tbe slender
ascyphous or mimitelv seypliiferous podetia, whicli are pulverulent
throughout. I t is very variable as to the basal thallus and the podetia,
the ditlerences in -wliicli give rise to the following varieties and
