‘430 LICHENACEI. [LECAN ORA. 
sessile, plane, brownish- or reddish-yellow; the thalline margin 
tumid, flexuose or subcrenate ; spores ellipsoid, 0,008-11 mm. long, 
0,005-7 mm. thick; paraphyses not discrete, tawny-yellow at the 
apices; hymenial gelatine scarcely tinged, but the thecz bluish with 
iodine.—Cromb. Lich. Brit. p. 53; Leight. Lich. Fl. p. 205, ed. 3, 
p. 189.—Lichen epanorus Ach. Prodr. (1798) p. 39. Lecanora albo- 
flavida Tayl. in Mack. Fl. Hib. ii. p. 260; Mudd, Man. p. 155.—Brit. 
Exs.: Leight. n. 397. - 
Well characterized by the citrine soredia with which the thallus is 
sprinkled throughout, and which often at length obliterate the subsqua- 
mulose granules. In the British specimens the hypothallus is scarcely 
visible, and the granules are more or less scattered. The apothecia are 
present on a single specimen sparingly and not very well developed. 
Hab. On rocks and walls, chiefly schistose, in maritime and uplend 
districts — Distr. Local in N. Wales, the 8. W. and Central Highlands of 
Scotland, and in 8S. W. Ireland.—B. M.: Cader Idris, Dolgelly (fruit), and 
Barmouth, Merionethshire. Ballachulish, Argyleshire; Glen Fender, 
Blair Athole, Perthshire. Dunkerron, co. Kerry.

or effuse, thinnish, areolato-verrucose or granulato-unequal, yellow- 
ish-green or straw-coloured (K+yellow, CaCl—); hypothallus in- 
distinct. Apothecia numerous, moderate, sessile, plane or subplane, 
concolorous with the thallus or pale-yellow or sublivid, often prui- 
noso-suffused ; the thalline margin persistent, subentire, at length 
angulose; spores ellipsoid, 0,009-11 mm. long, 0,005-6 mm. thick ; 
paraphyses not discrete ; epithecium granulose ; hymenial gelatine 
bluish, then somewhat sordid with iodine.—Cromb. Grevillea, xviii.

A much less variable plant than its trivial name imports and as was 
formerly supposed, in consequence of the separation by Nolewde on ana- 
tomical and other grounds of several species that follow. "With us the 
thallus is generally widely effuse and at times is very scanty. The apo- 
thecia are often crowded, angulose, almost obliterating the thallus. The 
ee a which are not unfrequent, are immersed, dark brown or 
ackish. 
Hab. On old pales and on the trunks of trees (chiefly pines) in mari- 
time and upland districts Distr. General and common in Great Britain, 
rare in the Channel Islands and apparently in Iveland.—B. M.: Island of 
Guernsey. Near Yarmouth, Suffolk; Walthamstow, Essex; Finchley, 
Middlesex; Shiere, Surrey ; St. Leonard’s Forest, Sussex ; Lyndhurst,
