Though reg-arded by some authors as the type of C. furcata, the 

 glabrous proliferous podetia, the characters of their apices and axils, and 

 the cristate margins of the apertures at once separate it from all the 

 vaiieties and forms of that species and render it specifically distinct. In 

 this country the apothecia are rare, though the spermogones are not 

 unfrequent. 



Hob. On the ground among mosses in upland and subalpine moorland 

 districts. Distr. Local and rare in N. England and among the Gram- 

 pians, Scotland. B. M. : Kildale Moor and Lounsdale, Cleveland, York- 

 shire. Ben-y-gloe Mountains, Perthshire; Ben-naboord and Upper Glen 

 Dee, Braemar, Aberdeenshire. 



Subsp. C. furcatiformis Xyl. Flora, 1874, p. 318. Podetia 

 slender, very much branched, caespitoso-fruticulose, the scyphi cris- 

 tato-ciliate at the margins. Cromb. Grevillea, xi. p. 113. Brit. 

 Exs. : Mudd, n. 12. 



Distinguished as a subspecies by the characters of the podetia and 

 their scyphi. The only British specimen seen is not very typical, and is 

 quite sterile. 



Hob. On the ground among mosses in upland districts. Distr. Appa- 

 rently extremely local and scarce in X. Kngland, though it no doubt 

 occurs also in the Highlands of Scotland. B. M. : Ingleby Park, Cleve- 

 land, Yorkshire. 



24. C. cenotea Schser. Spic. (1823) p. 35. Thallus nearly efo- 

 liolose or with small lobato-crenate squamules at the base : podetia 

 cylindrical, whitish or greyish-pulverulent, repeatedly proliferous, 

 the axils and apices often dilated, scyphoid and pervious, the aper- 

 tures (usually brownish within) denticulate (K , CaCl ). Apo- 

 thecia small, brown or pale ; spores moderate. Cromb. Grevillea, 

 xi. p. 113. Bceomyces cenoteus Ach. Meth. (1803) p. 345. 



The pulverulent podetia, with their pervious axils and apices, readily 

 distinguish this from C. crispata. They are glabrous and corticate at the 

 base, and from being repeatedly proliferous have a branched appearance. 

 In the few British speciniens seen the apothecia are very rare. 



Hub. On putrid stumps of trees in wooded upland situations. Distr. 

 Very local and scarce among the Grampians, Scotland, where it is con- 

 fined apparently to some of the remnants of the old Caledonian Forest. 

 H. M. : Black Wood of Rannoch, Perthshire ; Ballochbuie Forest, Brae- 

 mar, Aberdeenshire.
