PELTIGERA. | PELTIGEREI. 287 
1. P. malacea Fr. Lich. Eur. (1831) p. 44.—Thallus moderate, 
smooth, opaque, thickish, usually very minutely punctato-tomen- 
tellose, or obsoletely adsperso-pulverulent, livid-brown when moist, 
greyish-glaucous or glaucous-brown, or partly brownish when dry ; 
beneath densely tomentose, with confluent nerves and without 
veins, brownish-black, broadly whitish at the margin. Apothecia 
moderate, orbicular, ur nearly transverse, vertically adnate, brownish- 
red, the margin crenulate; spores elongato-fusiform, 3—5-septate, 
0,058-74 mm. long, 0,005-6 mm. thick.—Cromb. Journ. Bot. 1874, 
p. 147; Leight. Lich. Fl. ed. 3, p. 102 pro min. parte.—Peltidea 
malacea Ach. Syn. (1814) p. 240 pro parte. 
A very distinct species, thcugh having a superficial resemblance to 
some states of P.rufescens. The apothecia, which are not very numerous 
in our few British specimens, are adnate on short, somewhat broad thal- 
line lobules. 
Hab. Among mosses on rocks and about the roots of trees in moun- 
tainous regions.— Distr. Gathered only in the 8.W. Highlands and the 
N. Grampians, Scotland; may be found elsewhere.—B. M.: Inverary, 
Argyleshire ; Craig Cluny, Braemar, Aberdeenshire. 
6. microloba Nyl. ex Lamy, Bull. Soc. Bot., xxv. (1878), p. 378. 
—tThallus smaller, more divided; the lobes short, crisp, narrow. 
Apothecia smaller, at length incurved. 
Smaller in all its parts, and might be mistaken for P. polydactyla var. 
hymenina. In consequence of the thallus being more repeatedly lobed, 
the apothecia are more numerous than in the type. 
Hab. Among mosses on walls in upland tracts of mountainous dis- 
tricts—Distr. Found only in the S. Grampians, Scotland.—B. M.: Glen 
Lochay, Killin, Perthshire. 
2. P. canina Hoffm. Deutsch. Fl. ii. (1795) p. 106.—Thallus 
large, impresso-unequal, opaque, more or less adpresso-tomentellose, 
of moderate thickness, roundly lobed, brownish-green when moist, 
greyish when dry; beneath whitish, with prominent, concolorous or 
pale nerves, and long white rhizine. Apothecia moderate, sub- 
rotundate, at length revolute, brown or brownish-red, the margin 
nearly entire ; spores elongato-fusiform, 3—5-septate, 0,066-70 mm. 
long, about 0,004 mm. thick.—Mudd, Man. p. 52, t. 1. fig. 22; 
Cromb. Lich. Brit. p. 29; Leight. Lich. Fl. p. 107, ed. 3, p. 101.~
