A rather anomalous plant, which, if it does not descend from C. cervi- 

 cornis, with which it somewhat agrees in the character of the basal 

 squaimiles, is most probably referable to this species. The apothecia, 

 which in the absence of rightly developed podetia are sessile on the leaf- 

 lets, are numerous. 



Hob. On the ground among rocks in upland districts. Distr. Some- 

 what local, though not uncommon where it occurs in N. Wales, N. Eng- 

 land, S. Scotland, and among the Grampians. B. M. : Plinlimmon, Car- 

 diganshire ; IJolgelly and Rhewgreidden, Merionethshire; Bettws-y-Coed, 

 Denbighshire ; Battersby and Ayton Moors, Cleveland, Yorkshire ; 

 Ennerdale, Cumberland. New Galloway, Kirkcudbrightshire ; Damyat, 

 near Stirling ; Craig Calliach and Loch Eagh, Perthshire ; Lion's Face 

 and Glen Q.uoich, Braemar, Aberdeenshire. 



b'. Ascyplice. Podetia not scyphiferous. 



20. C. tnrgida Hoffm. Deutsch. Fl. ii. (1 795) p. 124. Thallus 

 foliaceous at the base ; leaflets large, laciniiform, variously divided 

 and crenate, sometimes few or evanescent, glaucous-green or whitish, 

 white beneath ; podetia laevigato-corticate, turgid, elongato-turbinate 

 or cylindrical, subscyphiferous or perforate at the apices, the margin 

 dentato-radiate, glaucous or pale-green (Kf-j- yellowish, CaCl ). 

 Apothecia brownish-red or pale ; spores oblong or oblongo-fusiform, 

 0,010-15 mm. long. 0,0035-40 mm. thick. Cromb. Lich. Brit,

When rightly developed (for the podetia are occasionally absent), this 

 is a very distinct species, which at first sight might be referred to the macro- 

 phylline section. As stated, however, by Nylauder (Syn. p. 205), its 

 true affinity is with C.furcata in the present section. In the only two 

 British specimens the podetia are here and there sprinkled with smaller 

 leaflets. There are no apothecia present, but the spermogones are abun- 

 dant. 



Hab. On the ground among heather in subalpine regions. Distr. 

 Extremely local and scarce among the N. Grampians, Scotland. B. M. : 

 Head of Glen Quoich, Braemar, Aberdeenshire. 



21. C. fnrcata Hoffm. Deutsch. FL ii. (1793) p. 115. Thallus 

 squamulose at the base or evanescent; podetia slender, elongate, 

 glabrous, sparingly branched, glaucous-white or brownish-green, 

 not perforate or subpervious at the axils, the branches somewhat 

 erect, attenuato-subulate and divergenti-furcate at the apices (K , 

 CaCl ). Apothecia small, subglobose, brown or reddish-brown ; 

 spores 0,010-13 mm. long, 0,0034-40 mm. thick. Nyl. Syn. i.
