podetial squamules crowded, swollen and branched, greyish 
glaucous or whitish. Cephalodia rather scarce, somewhat 
spherical, minutely granular on the surface, greyish, containing 
Stigonema. Apothecia terminal, at first thinly margined and 
plane, becoming convex and difform and often splitting, pale or 
dark-brown ; spores oblong-eilipsoid, obtuse, constantly 3-septate, 
18-28 yp long, 5-7 p» thick.—Cromb. in Journ. Bot. xiv. p. 359

Intermediate between St. coralloides and St. paschale. The 
podetia are subdecumbent, the squamules stouter more branched and 
less distinctly palmate than in S. paschale, but not coralloid.

or crenate, greyish white or whitish. Cephalodia warted, con- 
taining Stigonema. Apothecia terminal or subterminal, plane 
or convex, brown or dark-brown ; spores usually 3- sometimes

A plant of northern or cold regions and very rare in this country. 
Tt has frequently been confused with St. coralloides, but differs in 
the form of the podetial squamules, which are smaller and are never 
- coralloid. 
Hab. Among mosses on rocks and on the ground in alpine 
regions.— Distr. Rare in the northern regions of Scotland.—b. M. 
Upper Glen Dee, Braemar, Aberdeenshire ; Morven, Caithness.

Podetia small or moderate in size, up to 5 em. in height, attached 
below, nearly erect and branched above, attenuate and rarely 
sorediate at the apices, the axis glabrous ; podetial squamules 
whitish, subpeltate, at first somewhat globose then flattened and 
depressed in the centre, with a crenulate margin, sometimes 
discoid and crowded, often fewer towards the tips. Cephalodia
