Leight. in Ann. Mag. Nat. Hist. ser. 2, xviii. p. 282 (1856). 
Distinguished from G. proboscidea by the small crowded contorted 
pustules of the upper surface, which do not form into reticulate ridges 
as in that species. Gmelin (Linn. Syst. Veg. ii. p. 1874 (1796) ) 
describes his species Lichen Jacquini as smooth on both surfaces. 
Hab. On rocks and boulders in alpine situations.— Distr. Apparently 
confined to the higher Scottish Grampians.—B. M. Clova, Forfarshire ; 
Ben More, Perthshire; Lochnagar, Morrone and Ben-naboord, Braemar, 
Aberdeenshire; Ben Nevis, Invernessshire. 
6. G. flocculosa Turn. & Borr. Lich. Brit. p. 217 (1839).— 
Thallus small or moderate in size, thin, the upper surface smooth 
or partly flocculosely felted, in other parts beset with minute 
isidia-like elevations or with squamules, the margins often lacerate 
and reflexed, dull olive- or blackish-brown ; beneath smooth, sub- 
concolorous, lacunose-pitted (K —, CaCl = ,,;). Apothecia very 
rare, sessile ; spores oblong or oblong-ellipsoid, sometimes slightly 
curved, 18-27 p» long, 7-9 w thick.—Cromb. in Grevillea xy. 
p. 79 (1887) & Monogr. i. p. 333. G. deusta Ach. Meth. Lich.

Exsicc. Leight. n. 219. 
Distinguished by the dull frequently matted or squamulose surface 
and by the lacune of the smooth under surface, with the absence of 
fibrils or rhizine. The description of the spores is taken from 
Nylander (Lich. Scand. p. 119); it has not been possible to verify the 
details. Lichen deustus L. has been identified by Wainio (Medd. Soc. 
Faun. & Fl. Fenn. xiv. p. 7 (1888)) as probably synonymous with 
G. reticulata Th. Fr., which is not British. 
Hab. On rocks and walls in upland and mountainous districts.— 
Distr. Rather rare in Great Britain, not yet seen from Ireland.—B. M. 
Caer Caradoc, Shropshire; Cader Idris and Cellfawr, near Barmouth, 
Merioneth; Whitwick Rocks, Leicestershire; Egglestone, Durham ; 
New Galloway, Kirkcudbrightshire; Achosragan Hill, Appin and Ben 
Cruachan, Argyll; Ben Lawers, Perthshire; Glen Callater, Braemar, 
Aberdeenshire ; Ben Nevis, Invernessshire. 
7. G. polyphylla Hook. in Sm. Engl. FI. v. p. 217 (1833).— 
Thallus thin, polyphyllous or generally monophyllous, but with
