Species of the Cladoniei by the action of Hydrate of Potash. 413 
f. adspersa, Flk. = Coém. Cl. Belg. 175. In my herbarium 
I have this state from Gand (Abbé Coémans), Isus, Sima (Wil- 
ford), Australasia (Colenso). 
f. recurva (Hoffm.) (Dill. xvi. f. 27 pv) = Richardson, 26; 
Mudd, B. C. 48, 49; Coém. Cl. Belg. 185. 
This state I have from Louvain (Abbé Coémans), Bagni di 
Lucca (Dr. Deakin), Pyrenees (Dr. Deakin and Mr. Spruce), 
Yorkshire (Mr. Mudd), Leicestershire (Rev. A. Bloxam), and 
Shropshire. 
Var. corymbosa, Nyl. = Coém. Clad. Belg. 184, 187, 188, 
190, 191, 192, 198, 194, 195 ; Coém. 1030; Ny]. L. P. 22. 
This I have from Northern and Middle Islands and St. Pa- 
trick’s River (Colenso), Australasia (Dr. J. D. Hooker), British 
Columbia (Dr. Lyall), Subat (Dr. Philippe). 
Dr. Nylander notes these reactions in herb, Délise :—C. race- 
mosa, var. microcarpa, Dél., K—= (mihi corymbosa); C. racemosa, 
var. thyrsoidea, Dél.. K— = (corymbosa) ; C. tortuosa, Dél., 
K— = (corymbosa); C. racemosa, var. rangifera, Dél., is 
partly corymbosa, K—; and that Fries, L.8.58, “C. racemosa,” has 
K dilute fuscescens (= corymbosa) ; and also Fries, L. S. 117, 
“ C, subulata,’’ K dilute fuscescens, and comprises (1) subulata 
(=<), (2)corymbosa (= @), and (3) furcata, tenuis fuscescens 
Var. spinosa, Flk. (Dill. t. xvi. f. 25) = Coém. Clad. Belg. 
180, 186. 
This I have also from Kifferschwyl (Scherer), Genoa (Prof. 
De Notaris). 
Dr. Nylander (in litt.) remarks that it will be necessary to 
separate the C. spinosa (Flk.), given in Coém. Clad. Belg. 180, 
under the name C. furcata, and with the synonym “ C. fur- 
cata n racemosa suby. spinosa in hb. Flk.,” and again in No. 186 
under the name of “ C. furcata,” imasmuch as these two numbers 
have the free reaction K+, which here indicates only a distinet 
variety ; for there is frequently in-furcata and corymbosa a slight 
yellowish reaction which quickly turns to fuscescent. See also 
remarks under C. verticillaris, antead. 
Var. crispata, Flk.=Scher. 276, 277 ; Tuck. 31; Mudd, Br. 
C.45 ; Coém. Cl. Bs 199, 200; Richardson, 27,28, 29; Fellm. 
32, 33; Anzi, C. C. 22. 
Dr. Nylander (in Ut.) remarks that he considers crispata 
to be nothing more than a variety of furcata; just as amau- 
rocrea is of uncialis. 
I possess also specimens of crispata from Lheris (Dr. Philippe), 
Peklin (Dr. Harslingsky), Bagni di Lucea (Dr. Deakin). 
32. C. grypea, Tuck. (in Agass. Journey to Lake Superior, 
App.), 1s, according to Dr. Nylander (in Jitt.), distinct from ¢ur-
