The short (2 in. to 1 in. long), inflated, decumbent podetia, with their 
thickened and frequently dark brown apices, characterize this form. In 
more branched specimens the podetia are somewhat aggregate, but when 
simpler they are often somewhat discrete, owing to the nature of the 
habitat. The apothecia are extremely rare, and even the spermogones 
are seldom visible. 
Hab. In peat bogs on upland and subalpine moorlands. —Distr. Appa- 
rently local and scarce in N. Wales, 8. Scotland, among the Grampians, 
and in 8.E. and N.W. Ireland.—B. M.: Snowdon, Carnarvonshire. New 
Galloway, Kirkcudbrightshire; Craig Calliach and Moor of Rannoch,

n. 8. v. (1866) p. 111.—Podetia slender, close, erect, glabrous, subu- 
late, more or less branched, sparingly and narrowly scyphiferous, 
straw-coloured or whitish straw-coloured ; scyphi dentato-cristatc, or 
subulato-spinulose at the margins, often proliferous, rarely perforate 
at the axils (K—, K(CaCl)+yellow). Apothecia somewhat small 
or moderate, brown or pale-testaceous ; spores oblong, 0,009-12 mm. 
long, 0,0035 mm. thick.—Cromb. Lich. Brit. p. 22.—Cladina

crea Mudd, Brit. Clad. p. 27. Capitularia amaurocrea Florke in

xi. p. 115, var. myriocrea (? Flérke) Mudd, Brit. Clad. p. 27, Exs. 
n. 18, is referable to some condition of Cladonia furcata rather than 
to this species ; but the specimens seen are imperfect. 
From the closely allied C. uncialis this, when well developed, is easily 
known by the podetia being scyphiferous, more slender, and close. When 
ascyphous, as it often occurs, it 1s apt to be confounded with that species, 
though even then it must be regarded as distinct. With us the apothecia 
are very rare, and the spermogones only occasionally present. 
Hab, On the ground in moist places amongst heaths in upland and 
subalpine regions.— Distr, Found sparingly among the Grampians, Scot- 
land, and in N.W. Iveland.—B. M.: Rannoch Moor, Perthshire; Ben- 
naboord and Glen Dee (frt.), Braemar, Aberdeenshire. Near Kylemore, 
co. Galway.

Forh, xiii. (1873) p. 321.—Podetia short, more or less verrucose, not 
close, but vaguely directed, much branched, ascyphous, straw-coloured 
or greenish-grey ; branches short, subulate or furcate at the apices.
