Form 2. cerucha Xyl. Lieh. Scaud. (1861 ) p. 61 . — Podetia simple, 

 subveiitiicose, slightly attenuate at the apices ; scyphi luiimte, 

 narrow. — Cromh. (frevilloa, xv. p. 40. — Cenomyce dijitata c. cerucha 

 Ach. 8yu. (1814) p. 208. 



Tlie luorft tiirpfid and almost cormite podetia and the very small 

 narrow scyphi disting-iiish this form from the type. It is very rarely seen 

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

 spermogoniiferous or substerile condition. 



Bab. Among mosses on putrid stumps in upland wooded districts. — 

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

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

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

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

 pubproliferous. Apotheeia moderate. — Cromb. Greviliea, xi. p. 114.

Evidently but an accidental monstrosity, characterized by the more 

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

 Bpecimens the apotheeia are but sparingly present. 



Hab. On decaying trunks of trees in wooded mountainous districts. —

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

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

 ascyphous or minutely scyphiferous podetia, which aie pulveriileut 

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

 tia, the dirt'erences in which give rise to the following varieties and
