454 LICHENACEI. [LECANORA. 
148. L. nitens Ach. Syn. (1814) p. 335; Nyl. Flora, 1869, 
p. 298.—Thallus indetermiuate, thickish, subsquamulose, badious- 
brown, shining (K—, CaCl—); hypothallus black, little visible. 
Apothecia moderate, appressed, plane, brownish-black, the thalline 
margin entire, paler ; spores oblong, 0,009-0,018 mm. long, 0,0035- 
45 mm. thick—Cromb. Journ. Bot. 1882, p. 274.—Patellaria 
nitens Pers. Ann. Wetter. ges. Nat. xi. (1810) p. 12. 
Intimately related to L. badia, from which it differs chiefly in the form 
and size of the spores, whence Nylander J. c. is inclined to regard it as 
specifically distinct. The specimens gathered are well fertile, with the 
apothecia numerous, crowded, at times 2-3 confluent. As previously 
observed (p. 85), it is one of the hosts of Sphinctrina hylemoriensis. 
Hab. On schistose vocks in a maritime district.—Distr. Very local, 
though plentiful where it occurred in one of the Channel Islands.—B. M. : 
Chateau Point, Island of Sark. 
149. L. torquata Nyl. Act. Soe. Linn. Bord. sér. 3, t. i. (1856) 
p- 338.—Thallus continuous, smooth, rimoso-diffract, pale-murine 
or fumose (K—); hypothallus black, limiting the thallus. Apothe- 
cia submoderate, sessile, brownish-black ; the thalline margin pale, 
persistent entire, or flexuose ; spores narrowly ellipsoid, 0,005—7 
mm. long, 0,003-5 mm. thick.—Cromb. Journ. Bot. 1874, p. 147; 
Leight. Lich. Fl. ed. 3, p. 200.—Parmelia torquata Fr. Pl. Hom. 
(1825) p. 284. 
In general appearance subsimilar to Lecidea hochiana, but separated by 
the lecanorine apothecia. ‘hese, according to Fries (Lich. Europ. p. 147), 
are at times obsoletely pruinose, a character not apparent in the two 
British specimens seen. 
Hab. On moist rocks in a maritime district.—Distr. Only very spar- 
ingly in the Channel Islands—B. M..: Island of Alderney. 
I. Apothecia lecanorine; spores 8nz, pluriseptate, colourless. 
Spermogones with simple sterigmata and arcuate spermatia.

150. L. coccinea Cromb. Grevillea, xviii. (1890) p. 70.—Thallus 
effuse, thinnish or moderate, farinose or leprose, sulphur-coloured 
or white-yellowish (K-+yellow); hypothallus fibrillose, white. 
Apothecia innate or subsessile, moderate, plane or somewhat con- 
vex, crimson (K+-violet-purplish); the thalline margin whitish- 
pulverulent, often little conspicuous; spores elongato-fusiform, 
3-7-septate, 0,030-60 mm. long, 0,005-7 mm. thick, paraphyses 
not discrete; hymenial gelatine deep blue with iodine.—Lichen 
coccineus Dicks. Crypt. fase. i. (1785) p. 8, t. 2. f. 1; With. Arr. 
ed. 3, iv. p. 16; Eng. Bot. t. 223. Haematomma coccineum Mudd,
