The turgid deformed podetia and the form of their apices distinauish 

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

 of the preceding variety. It is very rarely fertile.

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

 appears t<) be constant to its characters. It is ea-ily recocniized by the 

 densely thyreoid apices of the podetia, which are usually shorter than in 

 the type. With us it is very seldom fertile. 



Hab. In moist places of woods and moor'auds in upland and subalpine 

 regions. — Distr. Local and scarce in England and Ireland : morf frequent 

 among the Grampians, Scotland. — -B. 31. : Charnwood Forest, Leicester- 

 shire ; lihewgreidden, X. Wah_-s ; Windermere, Westmorpland. Gleu

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

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

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

 occurs in a fertile condition. 



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

 tricts. — Distr. Rather local and f-carce 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, Aigvleshire ; Ran- 

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