beris (^9) ; form ahortiva Schaer, Ben Eaclian (88). Var. elongata 

 f. ecmocyna Nvl. On rock, 1000 ft., Llanberis (49). 



O. verticUlda (Hoffm.) Flk. Simonsbath, 1300 ft. (5), Ben 

 Eachan, 3100 ft., and Ben Lawers, 3900 ft. (88), Ben Doran, 

 2500 ft. (98). Var. siihcfrricomis Wain, is the common plant 

 known in this country as C. cervicornis (Crombie, p. 144). Form 

 stipota (Nyl.) is local but abundant on rocky subalpine or alpine 

 ledges, Snowdonia (49), Killin hills (88), Ben Doran (98). Var. cer- 

 vicornis (Ach.) Wain. ( = (7. sohoUfera of Crombie, p. 144), Ash- 

 burton (3), Blagdon hill (5), Stourhead (6). 



C. (legenerans (Flk.) Spreng. Form hypopliyUa Nj'l. near Har- 

 lech (48), Llanberis (49), Ben ' Doran (98)'. The type of C. decjene- 

 rans (f. etiphorea Ach.) is rare but var. anomcea (Ach.) Flk. is 

 fairly frequent on upland heaths and moorlands. Cwm Bychan (48), 

 Snowdonia (49), Castleton (57), Keighley (63). This variety is a 

 scyphiferous form of var. pliijUophora (Ehrh.) Flot. 



C. strepsilis (Ach.) W'ain.=:C. coralloidea (Ach.) Mudd. Llan- 

 beris (49). Recorded from Ben Lawers (88) and found there in 

 1913. 



C. fur cat a (Huds.) Schrad. Crombie, p. 150, states that the type 

 of C.furcata is Lichen suhulatus of Linnaeus. This is a slip since the 

 plant of Linnaeus is C. jimhriata var. suhulata. Hudson should be 

 substituted for Linnaeus in the text, as Hudson's plant is considered to 

 be typical C.furcata. The type and varieties corymbosa and spinosa 

 are common. Var. rigidula Mass. Buckden Pike (64), Ben Eachan 

 at 3000 ft. (88). Ysly. scahriuscula (Del.) Coem. {C. scahriuscula 

 Nyl.). Dittisham (3), Minehead and Blagdon Hill (5), Shapvvick 

 (6). Form adspersa (Flk.) = C'. adspersa of Crombie p. 158. Ex- 

 ford (5), Shapwick (6). The subspecies C. racemosa Nj'l. {sec. 

 Crombie p. 151) is difficult to correlate with any single plant of 

 Wainio. Dartmoor (3 & 4), Horner (5), Llanberis (49), Ben Lawers, 

 3900 ft. (88), Ben Doran (and f. tenuior, 98). Form recurva Flk. 

 Horner (5), Ben Lawers (88). All these plants had squamulose 

 podetia which Crombie gives as an important character of this sub- 

 species. It is not C. racemosa Hoff. nor is it var. racemosa Flk., 

 so that if it is retained as a subspecies, another name would have to 

 be given to it. It seems to be unnecessary to retain it. 



C. crispafa (Ach.) Flot. Exmoor, Hadden Down and Black- 

 downs (5;, Cwm Bychan (48), Llanberis (49), Nant-y-Ffrith (50 

 ■& 51), Skipwith (61). Var. dilacerata (Schaer.) Malbr. On 

 mossv rocks, Cwm Bvchan (48), Llanberis (49). Var. cetrarice- 

 formis (Del.) Wain. On peat, Haddon Down, 1000 ft. (5), Skip- 

 with Common (61). Var. gracilescens (Rab.) Wain. On damp 

 heath, Skipwith Common (6i). 



O. rang if or mis ii()^m. = C. pa ngens (Ach.) Flk. Form foliosa 

 Flk. On sand dunes, Kewstoke and Berrow (6). 



C. squamosa HofFm. Form ventricosa (Ach.) Fr. Achrioch 

 (88). Var. mullihrachiata f. pityrea (Arn.). On peat, Winsford 

 hill (5). Var. phyUocoma Wain. On tree, Ch)utsham (5). Var.
