286 LICHENACEL. [NEPHROMIUM. 
Applecross, Ross-shire. Fairhead, co. Antrim; Luggelaw, co. Wicklow ; 
Killarney, co. Kerry; Derryclare, Connemara, co. Galway. 
Form panniforme Cromb. Grevillea, xv. (1887) p. 77.—Thallus 
lobulato-dissected, closely imbricate, the lobules small, crowded, 
beneath dark-brown. Apothecia small. 
Has the appearance of other panniform conditions of foliaceous lichens. 
The apothecia, which in the specimens seen are with one exception very 
sparingly present, are small ial confined to the larger lobules. 
Hab. On the mossy trunks of trees, and on boulders in maritime and 
upland districts—Distr. Lozal and scarce in S.W. England and the W. 
Highlands of Scotland.—B. M.: Near Penzance, Cornwall. Barcaldine, 
Argyleshire ; Glen Lochay, Perthshire ; by Loch Linnhe, Inverness-shire. 
B. Hibernicum Nyl. ex Leight. Lich. Fl. ed. 3 (1879) p. 100.— 
Thallus with the medulla white (K+ purplish). Apothecia with the 
back of the receptacle smoothisn. Otherwise as in the type. 
A very distinct variety, if not subspecies, characterized by the white 
or whitish medulla, in which respect it resembles NV. levigatum. The 
chemical reaction, however, shows it to belong to MW. lusitanicum. In the 
specimens seen the apothecia have the back of the receptacle smooth or 
subsmooth; though as this occurs also in younger and muscicole states of 
the type, it can scarcely be regarded as of diagnostic value. 
Hab. On the trunks of old trees among mosses on rocks in maritime 
tracts.—Distr. Local and scarce in W. England, the W. Highlands of 
Scotland, and N.W. Ireland—B. M.: Near Walkingham, Devonshire ; 
Launceston, Cornwall; near Douglas, Isle of Man. Barcaldine, Argyle- 
shire; by Loch Linnhe, Inverness-shire. Doughbruagh Mts., co. Galway. 
52. PELTIGERA Hoffm. Deutsch. Fl, ii. (1795) p. 106 pro parte; 
Nyl. emend. Flora, 1866, p. 116.— 
Thallus fragile, opaque or somewhat 
shining, the cortical layer not conti- 
nuous on the under surface, which is 
generally nerved; gonidial layer 
composed of gonimia. Apothecia 
adnate on the front margin of the 
thalline lobules, ascending or hori- 
zontal; spores (6—)8nx, 3- or pluri- 
septate, fusiform, colourless; hyme- 
nial gelatine bluish with iodine. 
Spermogones not known. w

by the cortical layer not being conti-

when present, are composed of fasciculate filaments. All the European 
apecies occur in our Islands, and for the most part in considerable quantity.
