The turgid deformed podetia and the form of their apices distinguish 

 this. Apparently, however, it is only an abnormal and stunted condition 

 of the preceding variety. It is very rarely fertile. 



Hob. In moist places on moorlands in upland districts Distr. Local 

 and scarce in S.W. and Central England, in S. Scotland, and among the 

 Grampians. B. M. : Near Penzance, Cornwall ; Charnwood Forest, 

 Leicestershire. New Galloway, Kirkcudbrightshire ; Moor of Rannoch, 

 Perthshire ; Mar Forest, Braeiiiar, Aberdeenshire.

A well-marked variety, which alike in a young and mature state 

 appears to be constant to its characters. It is easily recognized by the 

 densely thy rs. old apices of the podetia, which are usually shorter than in 

 the type. With us it is very seldom fertile. 



Hal. In moist places of woods and moorlands in upland and subalpine 

 regions. Distr. Local and scarce in England and Ireland ; more frequent 

 among the Grampians, Scotland. B. M. : Charnwood Forest, Leicester- 

 shire ; Rhewgreidden, N. Wales ; Windermere, Westmoreland. Glen 

 Lochay, Perthshire ; Hill of Ardo, near Aberdeen, and Ben-naboord, 

 Braemar, Aberdeenshire ; Glen Nevis, Inverness-shire. Ballytore, co. 

 Kildare ; Kylemore, co. Galway. 



Form pnmila Leight. Ann. Mag. Nat. Hist. ser. 3, xviii. (1866) 

 p. 419. Podetia short, slender, very much, branched, rather fragile, 

 densely caBspitoso-pulvinulate. Cromb. Lich. Brit. p. 22 ; Grevillea,

The much smaller size (1-2 in. high) and the caespitose pulvinate habit 

 distinguish this form. It approaches states of Cladonia pungens, from 

 which the absence of any reaction with K keeps it distinct. It rarely 

 occurs in a fertile condition. 



Hob. In dry bare places on heaths and on turf-walls in upland dis- 

 tricts. Distr". Rather local and scarce in Great Britain, and not seen 

 from Ireland ; probably often overlooked. B. M. : Broadwater Forest, 

 Sussex ; Charnwood Forest. Leicestershire ; Rhewgreidden, Merioneth- 

 shire ; Burton Head, Cleveland, Yorkshire. Appin, Argvleshire ; Ran- 

 noch, Perthshire ; Glen Dee, Braemar, Aberdeenshiro ; Rothiemurchus, 

 Inyerness-shire.
