Often confused with C. digitata, from which it is well di.stiuguished by
the podetia. I t differs from the other varieties and forms of this species
in the more developed basal leaflets, and in the more or less squamuloso-
foliaceous podetia, which are either ascyphous and digitately branched, or
apically narrowly scyphiferous and proliferous. I t usually occurs well-
fruited.

incanum, scyphis cristatis Dill. AIuso. 94, t. 15. f. 17 b , o.— Though
there is no specimen of Liehen ventricosus in any of th e old herbaria,
yet from their references to the figure of Dillenius th ere is little
doubt th a t this was the p lan t intended by the above authors.
This seems to be only a larger and thicker form of var. coronata, somewhat
analogous to form monstrosa of the preceding species. As Lightfoot
/. c. remarks, “ it resembles in miniature a pollard tree wdth its lop on.”
In the only recent British specimen seen referable to this form, as in that
in Herb. Dill., there are no apothecia visible, but only decolorate spermogones.
Jlah. On peaty soil in upland moorlands.—D'lstr. Local and scarce in
N. England, but no doubt to be detected elsewhere.—B. AI. : Kildale

Form 2. carcata Nyl. Lioh. Scand. (1861) p. 62.—Podetia
moderate, granulato-qnilveruleut and p a rtly squamulose, simple or
subdivided a t the apices ; apothecia solitary or conglomerate.—

carcata Aoh. Lioh. Univ. (1810) p. 568.
The original specimen gathered in England by Turner having disappeared
from Herb. Ach., at Helsingfors, it is very doubtful what Acharius
really meint by bis carcata, whicli iu Syn. p. 2ii() he refers to Cenomyce
baedlaris as a variety. If really referable to this latter, Nylander suggests
in litt. th at it may be the same as bis v'ar. suhcoronata. Probably,
however, it is nothing very typical, .and if belonging to the present variety,
is only a simpler condition, and such as sometimes occurs in this country.

Readily recognized by tbe basal squamules bearing a very considerable
resemblance to those of Lecidea ostreata, from which when sterile it is
distinguished by tbe different reaction with K. In our Britisli specimens
the podetia are usually short, somewhat cornute at the apices, or when
better developed narrowly scyphiferous. The apothecia are extremely
rare, thougb tbe spermogones are not imfrequent.
Hab. On old mossy stumps of trees in upland wooded districts.—Distr.
Found sparingly only here and there tbroughout England.—B. AI. :
