6. 8. aggregatus Th. Fr. Lich. Arct. p. 280 (1860).—Thallus 
rather small, somewhat rigid, lobate and irregularly plicate, the 
lobes rather short, sometimes crenate, or often granular and 
crisp at the margins (I + red). Apothecia small to moderate 
in size, crowded, plane, becoming convex, reddish or dark-red, 
the margin thin, entire or becoming granular ; spores 8 (rarely 6) 
in the ascus, fusiform-cylindrical, straight or curved, pluriseptate, 
33-65 w long, 3-) uw thick——Mudd Man. p. 43.  Lichenoides

Distinguished from the preceding, to which it is closely allied, by 
the smaller thallus with short, irregularly wrinkled lobes, and by the 
longer spores. The apothecia, when present, are crowded, and are 
also somewhat larger and more irregular in form. 
Hab. Among mosses on the trunks of old trees in wooded inland 
tracts.— Distr. Rather rare in 8.W. and N. England, N. Wales, the 
W. Highlands of Scotland and §.W. Ivreland.—B. M. St. Leonard’s 
Forest and Henfield, Sussex; New Forest, Hants; Tunbridge Wells, 
Kent ; near Barmouth, Merioneth; Ingleby, Cleveland, Yorks; New 
Galloway, Kirkcudbrightshire ; Barcaldine, Argyll; near Killin and 
Aberfeldy, Perthshire; Loch Linnhe, Invernessshire; O’Sullivan’s 
Cascade and Muckross, Killarney, Kerry. 
7. 8. rupestris A. L. Sm.—Thallus broadly lobed, smooth or 
partly covered with blackish isidiose granules, dark-green or 
greenish-brown, the lobes rounded, entire, rather wavy, limp and 
flaccid when moist. Apothecia moder ate in size or rather small, 
scattered over the thallus, concave then plane, or somewhat 
convex ; paraphyses rather slender, conglutinate above ; spores 
fusiform-elongate, 3—5-septate, 23-28 p long, 7-10 thick.—

Easily distinguished by the spore characters and in a sterile 
condition by the large entire granular lobes. 
Hab, On old walls, rocks and trunks of trees in shady places in 
inland districts.—Distr. General and common where it occurs
