Mountain-rocks; abundant in the Highlands of Scotland.
3. G. deusta, Ach. (burnt Gyrophora); thallus membranaceous
roundly lobed brown upper-side more or less granulated,
under-side cellular and reticulated smooth and naked, apothecia
with circular plaits at length convex. Sm.—Ach. Syn. p. 66.—

Rocks in the Highland mountains.— This appears to me, both from
my own specimens and from the figure in E. Bot., to be too nearly
allied to G. probozcidea.
4. G. erdsa, Ach. (corroded Gyrophora); thallus simple membranaceous
rugged almost black irregularly lobed erose and
perforated at the circumference the segments convex, beneath
dark-grey somewhat granulated and partially shaggy, apothecia
convex variously plaited.

Frequent in rocky mountainous situations in the north of England,

5. G. cylindrica, Ach. (fringed Gyrophora); thallus coriaceous
simple or many-leaved slightly wrinkled dark bluish or
greenish-grey variously lobed and plaited coarsely ciliated at
the margin with black branched wiry bristles, beneath smooth
pale with scattered branching fibres, apothecia elevated nearly
plane variously plaited. Ach. Syn. p. 65.— Lichen cylindricus,

Abundant on mountain rocks.—This has more coriacecus/ro^ than
any of the preceding, of a blue-grey colour, especially when dry, and is
remarkable for the coarse black fringe with which its lobes are more
or less bordered. The name of this species and of G. jv'oboscidea have
been most unhappily chosen. The latter appellation might with some
propriety have been applied to the present species (as indeed it does
appear to have been, according to Smith); for the bristles of the margin
have a considerable resemblance (when magnified) to the proboscis, not
of the Elephant, but of the Elephant Beetle {Scarabcsus Elephas or S.
Hercides). It is used in Iceland occasionally as food and more frequently
for dyeing woollen cloth of a brownish-green colour.
6. G. mnrina, Ach. (mouse-shin Gyrophora); frond membranous
its margin plaited wavy and somewhat lobed minutely
