rounded, entire or slightly crenate; podetia rarely present, short, 
slender, glabrous, simple, sometimes bifid at the apices, ascyphous 
(K—,CaCl—). Apothecia solitary, turgid, capitate, brown ; spores

This anomalous plant resembles C. cariosa, but beside other characters 
differs in the absence of any thalline reaction. It is near C. pyxidata; 
but the form of the thallus and of the podetia (which when dry become 
shrunken and somewhat costate) entitle it to rank as a Hee it was so 
regarded by the older authors, and more recently by Nylander (‘ Flora,’ 
1874, p.70). The apothecia are nearly hemispherical, and much broader 
than the podetia. 
Hab. In moist places amongst heaths in wooded upland tracts.— Distr. 
Very sparingly in 8. England and 8.W. Scotland; probably overlooked 
elsewhere.—B, M.: Tilgate Forest, Sussex. New Galloway, Kirkcud- 
brightshire. 
6. C. pityrea Florke Clad. (1828) p. 79.—Thallus squamulose 
at the base; squamules minute, often evanescent, greyish-green 
above, white beneath; podetia somewhat short, slender, entirely 
furfuraceo-granulate, obsoletely and irregularly scyphiferous, greyish- 
white ; scyphi narrow, little evolute or divided, fimbriato-radiate 
and often proliferous at the margins (K—,CaCl—). Apothecia 
moderate or small, subpedicellate or sessile, pale- or dark-brown.—

Resembling generally C. fimbriata and var.chlorophea of C.pyxidata, yet 
so constant as to deserve to rank as a proper species. It is distinguished 
by the furfuraceo-pulverulent podetia and the minutely fimbriate narrow 
scyphi, which are pervious ornon-pervious. The apothecia are small and 
marginal on the scyphi, or large and subpedicellate, becoming dark in old 
age. 
Hab. On the ground among mosses and on dead stumps of trees in 
upland situations —Distr. Local and scarce in S. and N. England, and 
among the Grampians, Scotland; rare in N.W. Ireland and the 
Channel Islands.—B. M.: Noirmont, Island of Jersey. New Forest,
