Var. y. crenatum Nyl. Flora, 1875, p. 108.—Thallus email, smooth
or subsmooth ; lobes short, crowded, somewhat orenato-inoised a t
the margins. Apothecia small, scattered.—Cromb. Grevillea, xv.
p. 13.
A marked variety, at once distinguished by the entirely smooth thallus,
only a few lobes here and there being slightly rugulose. Its small
crowded lobés suggest L. pulvinatum. In the only fertile specimen seen,
the apothecia are but few.
Ilab. On the ground among schistose rocks in subalpine localities.—
Distr. Extremely local and scarce among the S. Grampians of Scotland.

The thaUus is cæspitose, moderate or small, often tinged pui-pliah, and
rather brittle when dry. I t somewhat resembles var. 8 of the preceding
in the herbarium, but is distinguished by its nearly erect laciniæ, revolute
at the margins. The apothecia are rare, and are but few when
present. On the thallus is sometimes found the parasitic Obryzum cor-
niciilatum.
