Form 2. cerucha Xyl. Lich. Scand. (1861) p. 61. Podetia simple, 

 subveutricose, slightly attenuate at the apices ; scyphi minute, 

 narrow. Cromb. Grevillea, xv. p. 46. Cenomyce diyitata c. cei-ucha 

 Ach. Syn. (1814) p. 268. 



The more turgid and almost cornute podetia and the very small 

 narrow scvphi distinguish this form from the type. It is very rarelv seen 

 with the apothecia well developed, but occurs for the most part in a 

 spermogoniiferous or substerile condition. 



linb. Among mosses on putrid stumps in upland wooded districts. 

 Distr. Very local and scarce in N. England, S. Scotland, and the N. 

 Grampians. B. M. : Windermere, Westmoreland. New Galloway, Kirk- 

 cudbrightshire ; Ballochbuie Forest, Braemar, Aberdeenshire. 



Form 3. monstrosa Xyl. I.ich. Scand. (1861) p. 61. Podetia 

 large, thickened, the scyphi difform and divided, shortly branched or 

 pubproliferous. Apothecia moderate. Cromb. Greviliea, xi. p. 114. 

 Sfifphophora digitata ft. monstrosa Gray, Nat. Arr. i. p. 422. 

 Ccno>ni/ce digitata e. monstrosa Ach. Syn. (1814) p. 268. 



Evidently but an accidental monstrosity, characterized by the more 

 turgid podetia and the abnormal form of the scyphi. In the'few British 

 specimens the apothecia are but sparingly present. 



Hnb. On decaying trunks of trees in wooded mountainous districts. 

 Dlsfr. Very local and scarce among the N. Grampians, Scotland. B. M.: 

 Craig Cltmy, Braemar, Aberdeenshire ; Rothiemurchus Woods, Inverness- 

 shire.

In its typical state this is distinguished from the preceding by the 

 smaller basal squamules, which are esorediate beneath, and by the slender 

 Mcyphoua or minutely scyphiferous podetia, which are pulverulent 

 throughout. It is very variable as to the basal thallus and the pode- 

 tia, the differences in which give rise to the following varieties and
