100 CYCLOCARPINES [PELTIGERA 
Hab. On turf walls and on the ground in fissures of rocks in 
upland and mountainous situations.—Dvzstr. Rare in the hilly regions 
of W. England, Wales, N. Ireland and 8S. Scotland, more frequent in the 
Grampians.—B. M. Whitcliff Rocks, near Ludlow, Shropshire ; Glyder 
Fawr, Carnarvonshire ; Kirkmichael and near Moftat, Dumfriesshire ; 
Habbies How, Pentland Hills near Edinburgh; Menstrie Glen, near 
Stirling; Stronachlachar, Finlarig, Killin, Ben Lawers, Glen Lyon

p. 101 (1857) & Syn. i. p. 318 (1860). (PL. 33.) 
Thallus foliose, horizontal, corticate on both surfaces, the 
under surface sometimes tomentose. Algal cells Nostoc. Apo- 
thecia marginal, roundish, adfixed on the lower surface of the 
thallus, finally directed upwards by the turning back of the 
fertile lobes, without a thalline margin; paraphyses simple, 
septate ; spores fusiform-oblong, usually brownish, 1—3-septate. 
Spermogones with septate sterigmata and small straight some- 
what dumbbell-shaped pleurogenous spermatia. 
The associated genus Nephroma which contains bright-green 
gonidia is not represented in the British Isles; the species are mostly 
found in cold regions. 
1. N. resupinatum Dalle Torre & Sarnth. Die Flechten 
Tirol, &e. p. 80 (1902).—Thallus suborbicular, lobate or laciniate- 
jobate, smooth or thinly tomentose, dull-glaucous or brown, paler 
beneath, densely tomentose and dotted with white granules (the 
medulla white, K —). Apothecia moderate in size, reddish- 
brown, unequal and crenulate at the margins; spores colourless 
or brownish, 20-24 yp long, 6-7 p thick.—N. tomentosum Nyl. in

A specimen from Robt. Brown marked subsp. ramewm agrees with 
the species, and is from the same locality. Both species and ‘ sub- 
species’’ are sprinkled with white dots (pseudocyphelle) on the under 
surface. The subspecies differs, however, in the longer narrower 
lobes and somewhat thinner texture of the thallus. There does not 
seem to be any authentic record of its occurrence in the British Isles. 
Hab. On the trunks of old trees in rocky upland situations.— 
B. M. Craig Cluny, Braemar, Aberdeenshire.
