shining, greenish-brown when moist, reddish-brown when dry, 
the lobes somewhat crumpled and crowded, sprinkled over the 
surface with roundish or irregular greyish-white soralia or with 
masses of isidia becoming sorediate, the margins of the lobes 
also frequently white-sorediate ; beneath densely tomentose, dark- 
brown, paler towards the circumference, with a few pseudo- 
cyphelle. Apothecia not seen rightly developed. S. Thouarsii

A tropical or subtropical lichen. Neither species nor variety 
occurs in Europe except in the British Isles, where the variety is 
widely distributed though not common. It is easily distinguished 
from the other species by the character of the soredia and by the 
pseudocyphelle, which are midway between cyphelle and pseudo- 
cyphelle. 
Hab. On mossy rocks and boulders and on the trunks of old trees. 
—Distr. Local and rare in the 8.W. and N. districts of Great Britain and 
Treland.—B. M. Near Bovey Tracey, Dartmoor, Devon ; near Dolgelly

moderate size, opaque or somewhat shining, generally reticulate- 
pitted, the lobes rather broad, crenate, dark-olive-green or dull- 
brown, the medulla usually citrine-yellow, the surface and 
the ridges between the pits yellow-sorediate ; beneath densely 
tomentose, with a few small yellow pseudo-cyphelle. Apothecia 
scattered or nearly marginal, moderate in size, dark-coloured, the 
margin crenate, at length nearly excluded; spores oblong- 
fusiform, brown, l-septate, 20-32 p long, 9-10 » thick.—Hook.

Easily recognized by the greenish-yellow soredia and pseudo- 
cyphelle ; the latter occur sparingly and irregularly in the form of 
minute pustules. 
Hab. Among mosses on trees and rocks in shady places, frequently 
in ravines.—Distr. Local in S.W. England and 8. Scotland, more 
frequent in the W. Highlands; scarce in 8., W. and N. Ireland.—
