From allied species this is distinguished by its thick, pulpy thallus, 
the repand, crenate, and often plicate lobes, and by the entire margin of 
the apothecia. Frequently seen in a rudimentary nostocine condition, 
and then not conspicuous unless in wet weather, when the thallus swells 
considerably. The apothecia are chiefly central, numerous, sometimes 
becoming confluent, and slightly convex, with thin recurved margin. 
Hab. On the ground and old walls, chiefly calcareous, in maritime and 
upland districts—Disér. General in the Channel Islands, and in most 
arts of Great Britain and Ireland.—B. M.: St. Saviour’s Hill, Island of 
nemasgs Reigate Hill, Surrey ; Shoreham, Kent; Lewes and Hurst-

Form compactum’ Nyl. Syn. i. (1858) p. 109.—Thalline lobes 
densely complicato-imbricate, somewhat rugose ; apothecia reddish.

—Collema compactum Ach. Syn. (1814) p. 313. 
The closely imbricate and rougher thallus distinguishes this form, 
which, however, is connected with the type by intermediate states, de- 
pending on the nature of the habitat. When fertile, the apothecia are 
numerous and become darker with age. 
Hab. On the ground in maritime and upland tracts.—Distr. Local and 
scarce in a typical condition, having been observed only in W. England 
and in the 8. and W. Highlands, Scotland.—B. M.: Kemble, Glouces- 
tershire; Malvern, Worcestershire. Island of Lismore, Argyleshire ; 
Killin, Perthshire.
