158 T.ICHENA.CTI. [CLADOMA. 



Aberdovey and Dolgelly, Merionethshire ; Cleveland, Yorkshire. Toug- 

 land, Kirkcudbrightshire ; Appin, Argyleshire ; Loch Linnhe, Inverness- 

 shire. Leenane, near Kylemore, co. Galway. 



Subsp. C. adspersa Nyl. ex Cromb. Grevillea, xi. (1883) p. 114. 

 Podetia moderate, somewhat slender, squamuloso-furfuraceous, 

 sparingly branched ; branches subsirnple, usually recurved, subulate 

 or furcately divided at the apices (K , CaCl ). Apothecia small, 

 dark-brown. Cladonia adspersa Cromb. Journ. Bot. 1876, p. 360. 

 Cladonia furrata var. adspersa Florke, Deutsch. Lich. (1821) 

 n. 198; Leight, Lich. Fl. ed. 3, p. 61. 



Though regarded by authors as belonging to C.furcata, var. recurva of 

 which it closely approaches, Nylander now rei'ers this to C. squamosa as 

 a subspecies well characterized by the podetia. With us, as elsewhere, 

 the apothecia are very rare, but the spermogones are frequent. 



Hab. Among mosses in woods and on shady rocks in upland districts. 

 Distr. Local in England and Ireland ; more general in the Highlands 

 of Scotland. B. M. : Shanklin Downs, Isle of Wight ; Epping Forest, 

 Essex ; near Oxford ; Charnwood Forest, Leicestershire. New Galloway, 

 Kirkcudbrightshire ; Barcaldine, Argyleshire ; Rannoch, Perthshire ; 

 Inglismaldie Woods, Kincardineshire ; Countesswells, near Aberdeen, and 

 Glen Callater, Braemar, Aberdeenshire ; Loch Linnhe, Inverness-shire.

27. C. subsquamosa Nyl. ex Cromb. Journ. Linn. Soc., Bot. xvii. 

 (1880) p. 560. Thallus foliaceo-squamulose at the base ; squamules 

 small, inciso-crenate, pale or greyish-green above, white beneath ; 

 podetia somewhat short or more elongate, branched, minutely squa- 

 mulose in the lower portion, granulate above, furcate, or radiato- 

 cristate and subcorymbose at the apices (K + yellow and then crim- 

 son, CaCl ). Apothecia small, reddish-brown. Cladonia delicata 

 var. subsquamosa Nyl. ex Leight. Ann. Mag. Nat. Hist. ser. 3, xviii. 

 (1866) p. 407 ; Cromb. Lich. Brit. p. 20 ; Leight. Lich. Fl. p. 59, 

 ed. 3, p. 55. Brit. Exs. : Mudd, n. 14 ; Larb. Caesar, n. 10 pro 

 parte ; Leight. n. 405; Bohl. n. 16. 



A somewhat variable plant, approaching in some of its smaller states 

 C. delicata, with which it agrees in the thalline reaction. In its larger 

 states again it is subsimilar to C. squamosa, from which it can rightly be 

 distinguished only on the application of K. The apothecia in our speci- 

 mens are rarely present. 



Hab. On rotten stumps of trees and among mosses in maritime and 

 upland districts. Distr. Rather local in the Channel Islands, S.W. and 

 N. England, N. Wales, S. Scotland, among the Grampians, and in E. and
