From var. pleurota of C. cornucopioides, with which it is comparable, 

 this is distinguished by the elongate, more turgid, and differently coloured 

 podetia. These are sometimes nearly fissured throughout, more or less 

 corticate, and when sterile are cornute. The apothecia, which are at 

 length conglomerate, are very rare in Great Britain, and are seldom seen 

 rightly developed. 



Hab. On the ground among heaths in wooded upland tracts. Distr. 

 Not very general nor common in W. and N. England, more frequent 

 among the Scottish Grampians, especially in Braemar ; not seen from 

 Ireland. B. M. : Hay Coppice, Herefordshire ; Guisboro' Moor and 

 Loundsdale, Cleveland, Yorkshire ; Wiudermere, Westmoreland ; Alston, 

 Cumberland. Appin, Argyleshire ; Craig Calliach and Rannoch, Perth- 

 shire ; Linn of Dee, Ben-naboord, and Loch Phadrig, Braemar, Aberdeen- 

 shire ; Rothiemurchus Woods, Inverness-shire ; near Forres, Elginshire. 



Form 1. gonecha Nyl. Syn. i. (1860) p. 222. Podetia longer, 

 gradually incrassate upwards from the base ; the scyphi dilated, 

 irregular, lacero-radiate. Apothecia somewhat large, confluent. 

 Cromb. Grevillea, xi. p. 114. Bceomyces deformis y. c/omchits Ach. 

 Meth. (1803) p. 335. 



This form is characterized by the larger, turgid podetia, and by the 

 irregular form of the scyphi. The only British specimens gathered are 

 sterile. 



Hab. On peaty soil amongst stunted heaths on subalpine moorlands. 

 Disfi: Very local and rare among the N. Grampians and in the N.W. 

 Highlands, Scotland. B. M. : Billochbuie Forest, Braemar, Aberdeeu- 

 shire ; Ben Ferrog, Inverness-shire. 



Form 2. pulvinata Nyl. Lich. Scand. (1861) p. 60. Thallus 

 pulvinato-congested at the base, the podetia short, narrow, cnrvato- 

 rlexuose and lacero-fissured, substerile. Cromb. Grevillea, xv. p. 46. 

 Cenomyce pidvinata Ach. Lich. Univ. (1810) p. 544. 



The small pulvinate basal thallus, consisting of minute imbricate leaf- 

 lets, and the less developed, curved, and fissured podetia are the dis- 

 tinctive marks of this form, which, however, is connected with the type 

 by intermediate states. It is never seen with the apothecia rightly 

 developed.
