Hudson’s Lichen scaber has been quoted as a synonym, but the 
description by him of the ‘black concave marginate scutelle ”’ 
refers it rather to Parmelia pubescens. The apothecia are rare. 
The spermogones are more frequent, and are usually borne on 
separate plants. 
Hab. Forming matted irregular tufts in somewhat large patches, 
on moist shady rocks, especially by streams. — Distr. General 
and fairly abundant in hilly and mountainous regions.—B. M.
