The smaller, smoother, more crisp thallus, and the difference of 
colour, as also the darker or brownish veins of the underside, distinguish 
this from P. canina, to which it is intimately allied. Whether it is to 
be regarded as specifically distinct is doubtful, since intermediate states 
occur by which they may be connected. The apothecia when present 
are numerous, though it is often sterile. 
Hab, Among mosses on shady rocks and the stumps of felled trees in 
maritime and mountainous districts.— Distr. Rather local and uncommon 
in the Channel Islands, W. and N. England, N. Wales, the 8.W. High- 
lands of Scotland, and S. Ireland.—B. M.: Island of Guernsey. Near

Well marked by the isidioso-subgranulose excrescences by which the 
margins of the lobes are bordered (often densely), and which may be 
also scattered here and there upon their surface. It is not uncommon in 
fructification, the apothecia sometimes becoming large. Pycnides similar 
to those of P. canina are frequent on the marginal squamules. 
Hab. Among mosses on shady rocks and walls, rarely on the ground, 
generally near water, in upland districts Distr. Somewhat local, but 
common in Great Britain and Ireland; rare in the Channel Islands; 
plentiful on the Grampians, Scotland.—B. M.: Rozel, Island of Jersey.
