From C. pyxidata, to which it is allied, this differs in the podetia being 
whitish-pulverulent, often more extended, with narrower scyphi. In 
these respects it is constant, and may with propriety be regarded as speci- 
tically distinct. It is a very variable plant in the characters of the 
podetia. Sometimes they become denudate, and in this case are often 
longitudinally ribbed (form costata Flérke, Mudd, Brit. Clad. p. 11; 
Leight. Lich. Fl. ed. 3, p. 58); and at other times they are once or twice 
proliferous (form prolifera Ach., Mudd, /. c.). The scyphi also are occa- 
sionally unequally denticulate at the margins (form denticulata Florke, 
Mudd, Man. p. 54, Brit. Clad. p. 10), and more rarely are cyathiform, 
with the margin squamulose (pterygota Flérke, Mudd, Brit. Clad. 
p. 11). These, however, are mere states of the type resulting from the 
nature of the habitat, and more than one of them may at times be seen 
on the same specimen. In this country the apothecia are rarely well 
developed.
