Hab. — On rotting wood, in very fine fruit. 15. Portach, 

 near Banchory, Aberdeenshire, along with Ccj)]i. catoudata 

 (Hiiben.) and Cepli. ciTvifuIia (Dicks.), /. Sim. Extremely rare. 



Found on the Continent. 



Obs. — Cej)h. cateiiuhd(( (Hiiben.) is very different in its larger 

 size and fulvous colour to C. hucantha, leaves subimbricate, 

 broader and more concave, when dry incurved and catenulate, 

 cells larger, but chiefly by the deeply triplicate perianth, with 

 mouth distinctly ciliolate. C. leiiccuitha is also certainly ver}' 

 distinct from CejjJi. lumdafoUa, Dum., which has larger, rhomboid- 

 rotund decurrent leaves, divided only to a third, sinus more or less 

 lunate, cells larger; perianth (in comparison with the leaves) much 

 shorter and like the calyptra fleshy (composed of several layers of 

 cells), &c. &c. "R S."
