292 LICHENACEI. [PELTIGERA. 
The shorter fertile lobules and the minute and often numerous apothecia 
are the distinguishing marks of this form, which is perhaps only a starved 
condition. 
Hab. On the ground among short mosses in upland districts.—Distr. 
Probably not rare in the mountainous regions of Great Britain, though 
as yet seen only in W. England and the Scottish Highlands—B. M.: 
Oswestry, Shropshire. Appin, Argyleshire; Killin, Perthshire; Apple- 
cross, Ross-shire. 
Var. 6. lophyra Nyl. Lich. Scand. (1861) p. 90.—Thallus 
brownish ; lobes scarcely ascending, rounded, beneath subvenose, 
brown or brownish-black. Apothecia small, rotundato-oblong or 
sometimes transverse.—Cromb. Lich. Brit. p. 29.—Peltidea hori- 
zontalis y. lophyra Ach. Lich. Univ. (1810) p. 516. 
Paid eee by the roundly-lobed thallus, scarcely veined beneath, 
and the form of the apothecia. In the only British specimen seen these 
are transverse, whence it was considered by Acharius as a variety of 
P. horizontalis, from which, however, it otherwise entirely differs. 
Hab. On decayed mosses upon boulders in upland districts.—Distr. 
Very local and scarce on the 8. Grampians, Scotland (though recorded 
from England by Acharius).—B. M.: Finlavig, Killin, Perthshire. 
Var. y. hymenina Nyl. Lich. Scand. (1861) p. 90.—Thallus with 
paler subconfluent veins on the under surface. Apothecia rotun- 
dato-oblong.—Cromb. Journ. Bot. 1876, p. 360; Leight. Lich. Fl. 
ed. 3, p. 104.—Lichen polydactylos var. 2, With. Arr. ed. 8, iv. 
p. 69. Peltidea hymenina Ach. Meth. (1803) p. 284. 
Differs in the character of the thallus beneath, and in the form of the 
fructification. The thallus when dry is cervine-coloured, and the apo- 
thecia are generally but sparingly present. 
Hab. Among mosses on the ground and about the roots of old trees in 
upland wooded districts.—Distr. Not general nor common in the hilly 
and mountainous tracts of W. and N. Ireland, N. Wales, and the W. 
Highlands of Scotland; rare in N.W. Ireland.—B. M.: Bocconoc, Corn- 
wall; Malvern, Worcestershire; Harboro’ Magna, Warwickshire ; Hope 
Bowdler and High Rock, Bridgenorth, and near Caer Caradoc, Shrop- 
shire ; near Aberdovey, Merionethshire ; Llanberis, Carnarvonshire; Kil- 
dale Moor, Cleveland, Yorkshire ; Windermere, Westmoreland; Alston, 
Cumberland. Kenmure, near Glasgow; Inverary and Appin, Argyle- 
shire ; Glen Lochay and Ben Lawers, Perthshire. Dawros River, Con- 
nemara, co. Galway. 
7. P. scutata Leight. Lich. Fl. (1871) p. 110.—Thallus small, 
thinnish, sinuato-lobed, more or less minutely depresso-granulate, 
undulato-crenate, crisp and cesio-sorediate at the margins, greyish- 
green when moist, pale-greyish or greyish-red when dry; beneath 
whitish, with pale-brown nerves and modcrate whitish rhizine. 
Apothecia small, suborbicular, ascending, brown or reddish-brown, 
the margin crenate and inflexed ; spores elongato-fusiform, usually 
3-septate, 0,044-60 mm. long, 0,004-5 mm. thick.—Leight. Lich. 
Fl. ed. 3, p. 104.—Peltigera polydactyla var. scutata Cromb. Lich.
