Differs from the preceding in the small digitately lobed thallus, the 
paler nerves, the smaller apothecia, and the longer spores. It so resembles 
P. polydactyla that it might readily be confounded with some of the 
states of that species. The thallus, which is sometimes pruinose, often 
grows in a scattered manner; the apothecia are numerous, nearly all the 
lobes being fertile. 
Hab. On the ground among mosses and short grass, as also on the 
stumps of felled trees in maritime and upland districts.— Distr. Some-

5. P. scabrosa Fr. fil. N. Act. Reg. Soc. Sc. Upsal. ser. 3, t. iii. 
(1861) p. 145.—Thallus moderate, subcoriaceous, very finely and 
minutely scabrid, roundly lobed, dpaque, pale-lurid or greyish-pale, 
beneath whitish, subreticulate, with pale, nearly confluent nerves, 
blackish in the centre. Apothccia moderate, .subrotundate, at 
length revolute, brownish-red or dark-chestnut, the margin sub- 
crenulate; spores 0,068-80 mm. long (or even longer), 0,004— 
0,005 mm. thick.—Cromb. Journ. Bot. 1885, p. 195. 
A distinct species allied to P. rufescens, but differs in the minutely 
scabrous not tomentellose thallus, and in the more elongate spores. 
From P. scutata it is distinguished not only by the larger thallus and. 
apothecia and the form of the lobes, but also by the almost verrucose 
epithallus, and the more septately divided spores. It is a plant of a 
boreal type, and is fertile only in subarctic regions. 
Hab, On turf-covered walls ina mountainous region.— Distr. Extremely 
local and scarce on the N. Grampians, Scotland.—B. M.: Between Cor- 
riemulzie and Inverey, Braemar, Aberdeenshire.

Thallus thinnish, digitato-lobed, ascending or suberect, glabrous 
and shining, smooth or obsoletely impresso-unequal, glaucous-green 
when moist, livid- or pale-glaucous or pale-brown when dry, beneath 
nearly glabrous, whitish or white, reticulate with coarse blackish- 
brown nerves, which are pale-reddish towards the circumference. 
Apothecia small, longitudinal, brown or reddish-brown, the margin
