From C. pi/.ndata, to which it is allied, this differs in the podetia being 

 whitish-pulverulent, ofttm 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 FliJrke, Mudd, Brit. Clad. p. 11 ; 

 Leight. Lich. Fl. ed. 3, p. 58) ; and at other times they are once or twice 

 proliferous (form ■prolif\-ra Ach., Mudd, /. c). The scyphi also are occa- 

 sionally unequally denticulate at the maroins (form denticidata Florke, 

 Mudd, Man. p. 54, Brit. Clad. p. 10), and more rarely are cyathiform, 

 with the margin squamulose {pteri/gota Florke, Mudd, Brit. Clad. 

 p. 11). These, however, are mere states of the type resulting from the 

 natm-e 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.
