Differs in the colour, which is due to the infiltration of ferric 
oxide. The thalline squamules are generally contiguous. 
Hab. On rocks and boulders, chiefly schistose, in mountainous 
regions.— Distr. N. Wales and the Grampians, Scotland.—B. M. 
Dolgelly, Merioneth ; Aber and Beddgelert, Carnarvonshire; Angle- 
sea; Achosragan Hill, Appin, Argyll; Killin, Ben Lawers and Ben 
Vrackie, Perthshire; Glen Cluny, Braemar, Aberdeenshire; Glen 
Nevis, Invernessshire. 
9. A. peliocypha Th. Fr. Lich. Arct. p. 89 (1860).— 
Thallus thickish, cracked-areolate, of crowded somewhat crenate 
squamules, tawny-brown, somewhat shining, blackish beneath 
(K(CaCl)—). Apothecia rather small, immersed then plane, 
reddish-brown, the disc granular-papillate, the thalline margin 
persistent, crenulate and flexuose ; paraphyses stoutish, irregular, 
variously septate and clavate or ovoid at the tips; spores 
numerous, oblong-cylindrical, 3-5 p long, 1-1°5 yp thick ; 
hymenial gelatine bluish then quickly wine-red with iodine.—

Distinguished by the contrast in colour between thallus and 
apothecia and by the granular-papillate discs of the latter. 
Hab. On granitic rocks in alpine situations ; recorded by Crombie 
from Braeriach, Braemar, Aberdeenshire. 
10. A. rhagadiza Oliv. Lich. Eur. fase. ii. p. 80 (1909),.— 
Thallus spreading, unequal, variously and deeply cracked, dark 
olive-greyish, dark beneath (K—CaCl—) Apothecia small, 
innate, concave or plane, reddish-flesh-coloured ; paraphyses 
slender ; spores oblong, narrow, about 3°5 p long, 1 yp thick ; 
hymenial gelatine tawny-wine-coloured with iodine.—Lecanora 
rhagadiza Nyl. in Flora Ixiv. p. 178 (1881) ; Cromb. in Grevillea 
x. p. 23 (1881) & Monogr. i. p. 485. 
Considered by Nylander as nearly related to ‘‘ Lecanora rufescens.”” 
It differs in the colour of the thallus and of the apothecial disc, which 
may possibly be the effect of the damp habitat. 
Hab, On moist sandstone rocks in a maritime locality.—B. M. 
Whitehaven, Cumberland (the only record). 
11. A. discreta Th. Fries Lich. Scand. p. 217 (1871).— 
Thallus effuse, warted- or angular-areolate, the areole contiguous 
or discrete, dark-brown, dark beneath (K—CaCl—). Apothecia 
minute, impressed, somewhat angular, dark-brown, the thalline 
margin obtuse or indistinct ; paraphyses stoutish or slender, 
somewhat clavate and generally reddish-brown at the extreme
