Laciniz short, congested and complicate, often flexuose ; soredia 
large, often confluent. Apothecia very rare.—Leight. Lich. FI.

Distinguished from the species by the dwarfed, pulvinate habit of 
growth, and by the occasionally abundant soredia. Apothecia not 
seen on British specimens. 
Hab. On trees, palings, etc., occasionally on rocks and stones in 
maritime and upland regions.—Distr. Local though plentiful where it 
occurs throughout England, rare in Scotland.—B. M. Near Penzance, 
Cornwall; Taunton, Somerset ; near Lyndhurst, New Forest, Hants ; 
Penshurst, Kent; Gopsall, Leicestershire; Lakenham, Suffolk ; 
Salisbury Crags, Edinburgh. 
8. R. evernioides Nyl. in Act. Soc. Linn. Bord. sér. 3, i. 
p-. 293 (1856).—Thallus greyish or greenish straw-coloured, sub- 
erect, of rather large plane irregular lacinix, variously branched 
and lacerate, crowdedly reticulate-wrinkled and scrobiculate (not 
longitudinally nerved), with scattered roundish superficial or 
marginal soralia frequently on the lines of the reticulation. 
Apothecia rare, marginal, moderate in size, wrinkled beneath ; 
spores oblong, slightly curved, 10-15 » long, 3-5 p thick.—

Easily distinguished by the scrobiculate thallus from all forms of 
ht. pollinaria with which it mainly agrees in the internal structure 
except for the strengthening strands, which are absent in this species. 
The thallus, which varies greatly in the form and width of the laciniz, 
is rather flaccid. Crombie’s f. monophylla is merely a growth form. 
f. evernioides is, in Europe, found only in the West. 
Hab. Qn old trees, chiefly oaks, in wooded upland districts.— 
Distr. General and common in $. and W. England and §. and E. 
Ireland ; rare in the Channel Islands, not seen from Scotland.—B. M.

Thallus saxicolous, without soredia.
