Form epiphylla Scher. Enum. p. 191 (1850).—Basal squamules. 
present; podetia extremely reduced or wanting. Apothecia 
conglomerate, subsessile on the squamules.—Mudd Man. p. 53;

(1865). Lichen epiphyllus Ach. Lich. Suec. Prodr. p. 185 (1798). 
A curious and rare form of doubtful affinity. The apothecia are 
more or less sessile on the basal thallus. In the specimen collected 
by Mudd in Yorkshire the apothecia are scarcely visible. 
Hab. On the ground in inland places.—Distr. Rare in E. and N. 
England, not recently found.—B. M. Epping Forest, Essex; Ayton, 
Cleveland, Yorkshire (doubtful). 
Var. pocillum Fr. Summ. Veg. p. 110 (1846).—Basal 
squamules deeply crenate, firm, often closely appressed, greyish 
or usually greyish-tawny ; podetia very short, closely granulate. 
verrucose.—Cromb. Lich. Brit. p. 18 & Monogr. i. p. 130;

Exsicc. Johns. n. 286. 
The basal thallus is occasionally orbicular and partly crustaceous. 
Apothecia are rare. 
Hab. On bare soil on banks and heaths maritime and inland.— 
Disir. Seen only from a few localities in the Channel Islands, 
England and Scotland, but probably common.—B. M. The Vale, 
Guernsey ; near Bodmin, Cornwall; Bathampton Downs, Somerset ; 
Charnwood Forest, Leicestershire; Barmouth, Merioneth; Redcar 
and near Ayton, Cleveland, Yorkshire; Tongland, Kirkcudbrightshire ;

nessshire. 
Var. chlorophea Floerk. Clad. Comm. p. 70 (1828).—Basal 
squamules rather small, often pulverulent at the margins ; podetia 
rather long, mostly granular below and becoming pulverulent 
upwards, greenish or sulphur-coloured, the scyphi usually narrow 
and often slightly contracted at the margin, sometimes proliferous.

Differs from the species in the general breaking down of the 
sranules to a sorediose powder on the upper part of the podetium.
