Form 3. pleolepidea Xyl. Lich. Scand. (1861) p. 5-4. Podeiia 

 simple or sparingly branched above, usually somewhat curved, 

 ascyphous, densely covered with rigid squamules. Apothecia nume- 

 rous, dark-brown. Cromb. Grevillea, xii. p. 91. 



The podetia, which Nylander (/. c.) describes as being 2-3 in. long, are 

 with us much smaller, from to 1 in. Occasionally, where less squamu- 

 lose, they are white-punctate. In the two specimens gathered the apo- 

 thecia are more or less aggregate. 



Hob. Among short mosses on the ground in alpine places./)^'. 

 Very local and scarce among the N. Grampians, Scotland. B. M. : Near 

 the summit of Morrone, Braemar, Aberdeenshire. 



Var. /3. anomaea Florke, Clad. (1828) p. 43. Podetia short, 

 slender, rugose ami more or less squamulose ; scyphi usually ra- 

 diately divided. Apothecia either sessile or pedicellate, dark brown.

This variety is distinguished by the podetia, which are from | to 1 in. 

 high, being either densely or partially covered with squamules, and by 

 the form of their scyphi. As observed, however, by Nylander (Syii. 

 p. 200), the podetia are scarcely scyphiferous, but rather radiato-partite 

 (cfr. Ach. Lich. Univ. p. 552). The apothecia are either simple or con- 

 glomerate, becoming in age somewhat large. 



Hah. On the ground on heaths and on rotten wood in upland situa- 

 tions. Di'str. Apparently local and scarce in S.W. and N. England, in S. 

 Scotland, and among the Grampians ; no doubt overlooked elsewhere. 

 B. M. : Lakenham, Norfolk; near Hurstpierpoint, Sussex; Dartmoor, 

 S.Devon; Mai vern, Worcestershire ; Burton Head, Cleveland, Yorkshire. 

 Pentland Hills, near Edinburgh ; Craig Calliach, Perthshire ; Glen Cal- 

 latei- and Glen Quoich, Braemar, Aberdeenshire. 



Subsp. 1. C. trachyna Nyl. ex Xorrl. Not. Sallsk. pro F. et Fl. 

 Fenn. Fdrh. n. s. x. (1873) p. 319. Podetia elongate, or mode- 

 rate, cylindrical, squamulose, scyphiferous, sordid-whitish ; scyphi 

 denticulato-proliferous and radiato-cristate at the margins. Apo- 

 thecia minute, brown. Cromb. Grevillea, xi. p. 113. Cladonia 

 degenerans f. trachyna Mudd, Brit. Clad. p. 18. Bcvomyces trachynu* 

 Ach. Meth. (1803) p. 348. 



From the preceding varieties and forms this differs in the form of the 

 scyphi, which give it somewhat the appearance of C. crispata. This and 

 its general habit seem to entitle it to rank as a subspecies. The podetia 

 are normally from 3 to 5 in. long ; but they sometimes occur less developed. 

 The apothecia are at length dark brown, but our more elongate states are 

 only speruiogoniiferous. 



Hub. On heathy ground amongst mosses in upland and subalpine 

 regions. Dlstr. Local and scarce among the Scottish Grampians. 

 B. M. : Raimorh, Perthshire: Ben-naboord, Braemar, Aherdecnshire.
