172 LICHENACEI. [CLADOXIA. 



Cladonia cocci/era e. macilenta a. clavata Mudd, Brit. Clad. p. 31. 

 CoraHoides ramulosum, tuberculis coacineis Dill. Muse. 96, t. 15. 

 f. 19 G.Brit. Exs. : Mudd, Clad. n. 70 ; Bohl. n. 80. 



From C. macilenta (typical), to which it is similar and with which it 

 has usually been confounded, this species is at once separated by the 

 absence of any reaction with K. In other respects it differs in the 

 podetia being more slender and granuloso-pulverulent. Our British 

 specimens are but rarely well fertile. 



Hob. On the bare ground and turf-walls in upland situations. Distr. 

 Seen only from a few localities in S. England, the Scottish Grampian*, 

 and N.W. Ireland. B. M.: Bournemouth, Hampshire; Wadebridge, 

 Cornwall. Appin, Argyleshire; Glen Lochay and IJannoch, Perthshire; 

 Hi'ls at Nigg, Kincardineshire ; Castleton of Braemar, Aberdeenshire. 

 Near Kylemore, co. Galway. 



Form pityropoda Nyl. ex Cromb. Grevillea, xi. (1833) p. 115. 

 Podetia somewhat thick, granuloso-rugose, simple or shortly divided 

 at the apices. 



This form, which is distinguished by the thicker and coarsely grauulose 

 podetia, is analogous to var. scabrosa of Cl. macilenta. Our British spe- 

 cimens are for the most part well-fruited. 



Hab. On the ground and turf-walls in upland tracts. Distr. Local 

 and scarce in N. England, among the Grampians, Scotland, and in N. 

 Ireland. B. M. : Kildale Moor, Cleveland, Yorkshire. Appin, Argyle- 

 shire; Rannoch, Perthshire. Colin Glen, near Belfast, co. Antrim ; Con- 

 nemara, co. Galway. 



Var. j3. subcoronata Nyl. ex Cromb. Grevillea, xii. (1884) p. 92. 

 Podetia thickish, granulato-squamulose, somewhat simple or digi- 

 tately branched towards the apices. CoraHoides ramulosum, tubfr- 

 culis coccineis Dill. Muse. 96, t. 15. f. 19 A, B. Lichen digitatus pro 

 parte as it appears of our older authors. Brit. Exs. : Mudd, Clad. 

 n. 72 pro parte. 



Differs in the podetia being more or less squamulose and often digi- 

 tately divided, so that it has a considerable resemblance to states of var. 

 coronata of the preceding species. The British specimens seen are well 

 fertile. 



Hab. On the ground in upland moorlands Distr. Local and rare in 

 S.W. and N. England, among the S. Grampians, Scotland, and in N.W. 

 Ireland ; no doubt overlooked elsewhere. B. M. : Near Hunter Tor, 

 Dartmoor, Devonshire; St. Breward, Cornwall; Ingleby Park, Cleve- 

 land, Yorkshire. Glen Lochay, Killin, Perthshire. Letter Hill, Conue- 

 inara, co. Galway. 



37. C. Floerkeana Fr. Sched. Crit. iii. (1824) p. 18. Thallus 

 squamulose at the base ; squamules small, inciso-lobed or crcnate, 

 greenish-white above, white beneath, often evanescent ; podetia 

 cylindrical, slender, corticate, glabrous, simple or shortly divided at 

 the apices, greyish- white, greyish-green or brownish (K , CaCl ). 

 Apothecia moderate, usually conglomerate ; spores 0,008-10 mm. 

 long, 0,003 mm. thick. Cromb. Grevillea, xi. p. 115, Lich. Brit.
