Form 2. cerucha Nyl. Lich. Scand. (1861) p. 61.—-Podetia simple, 
subventricose, slightly attenuate at the apices; scyphi minute, 
narrow.— Gromb. Grevillea, xv. p. 46. —Ceromyce digitata c. cerucha 
Ach. Syn. (1814) p. 268. 
The more turgid and almost cornute podetia and the very small 
narrow scyphi distinguish this form from the type. It is very rarely seen 
with the apothecia well developed, but occurs for the most part in a 
spermogoniiferous or substerile condition. 
Hiab. Among mosses on putrid stumps in upland woeded distriets.— 
Distr. Very local and scarce in N. England, 8. Scotland, and the N. 
Grampians.—B. M.: Windermere, Westmoreland, |New Galloway, Kirk- 
cudbrightshire; Ballochbuie Forest, Braemar, Aberdeenshire. 
Form 3. monstrosa Nyl. Lich. Seand. (1861) p. 61.—Podetia 
large, thickened, the seyphi difform and divided, shortly branched or 
subproliferous. Apothecia moderate.—Cromb. Greviliea, xi. p. 114. 
—Scyphophora digitata B. monstrosa Gray, Nat. Arr. i. p. 422. 
Cenomyce 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. _ 
Hab. On decaying trunks of trees in wooded mountainous districts.— 
Distr. Very local and scarce among the N. Grampians, Scotland.—B. M.:. 
Craig Cluny, Braemar, Aberdeenshire; Rothiemurchus Woods, Inverness- 
shire. 
35. C. macilenta Hoffm. Deutsch. Fl. ii. (1795) p. 126.—Thallus 
squamuloso-foliaceous at the base, the squamules small, incised or 
crenato-lobed, glaucous-greenish or glaucous-greyish above, white 
beneath; podetia cylindrical, slender, simple or sometimes shortly 
divided at the apices, ascyphous or rarely narrowly and minutely 
scyphiferous, whitish-pulverulent (K+ yellow, CaCl—). Apothecia 
small, terminal, solitary or tuberculoso-confluent.—Cromb. Lich.

In its typical state this is distinguished from the preceding by the 
smaller basal squamules, which are esurediate beneath, and by the slender 
ascyphous 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
