Species of the Cladoniei by the action of Hydrate of Potash. 411- 
Var. ochrochlora, Flk. (Nyl. Syn. i. p. 198) = Arnold, 265 ; 
Scher. 640; Anzi, C. C. 8; Coém. 1019; Hepp. 540; Coém. 
Cl. Belg. 54, 81, 82, 83, 84, 85, 86, 110; Mudd, Br. Cl. 23, 
24, 25, 26. 
I possess also specimens from Austria (Dr. Holzinger), 
Lheris (Dr. Philippe), Bagni di Lucca (Dr. Deakin). 
21. C. verticillata, Flk. (Vaill. Par. t. xxi. f.5; Dill. t. xiv. 
f. 6, cg, u) = Coém. 1020; Tuck. Am. Sept. 26; M. & N. 644; 
Coém. Cl. Belg. 17; Wright, Cuba, 28; Scher. L. H. 458; 
Mudd, Br. Cl. 3. 
In my herbarium are also specimens from Untersontheim 
(Kemler), and Barmouth, North Wales. 
Var. sobolifera, Dél. (in Dub. Bot. Gall. p.631) = Scher. L. He 
62, 63, 274,275; Tuck. Am. Sept. 27; Coém. Cl. Belg. 14, 15, 
16; Leight. Exs. 14; Mudd, Br. Cl. 2. 
I have also specimens from Tatra, Hungary (Dr. Harslingsky), 
Subat (Dr. Philippe), Caer Caradoc and Lawrence Hill, Shrop- 
shire, Barmouth, North Wales. 
The reaction K— is in the above fuscescent. Coémans (Clad. 
Achar.) regards verticillata as the type of the species, and cer- 
vicornis (our sobolifera) as a simple microphylline variety. The 
true cervicornis has a reaction K+, which separates sobolifera 
(K—), which has hitherto, from external aspect, been confused 
and intermingled with it. Dr. Nylander (im litt.) informs me. 
that C. cervicornis of Délise herb. has K+, and C. sobolifera of 
the same collection has K—. 
22. C. decorticata (Fr) (Nyl. Syn. i. 199) = Scher. 279; 
Hepp. 545; Anzi, C. C.5; Coém. Clad. Belg. 21. 
. This I possess also from Upsal (Dr. T.M. Fries), Dageré, Fin- 
land (Abbé Coémans). Distinct from cariosa (K+) by reaction 
K—, and from pywidata var. decorticata (Flk.) by the different 
squamules. 
Dr. Nylander (in Witt.) says C. decorticata (Fr.), Nyl. (of 
which C. Mougeotii, Dél., is a spermogoniferous state), has K—. 
23. C. degenerans, Fk. = Fr. L. 8. 54 (fide spec. a Nyl.); 
Richardson, Arct. Am. 19, 20, 21, 22, 28, 24, 25; Anzi, C. C. 
13; var. trachyna(Ach.) = Fellm. Lapp. 34. 
Of this species I have specimens also from Holm (Dr. Ny- 
lander), Upsal (Dr. T. M. Fries), Untersontheim (Kemler), 
Mount Spliigen, Grimsel, Vall. Gastern (Scherer), Leicestershire - 
(Rev. A. Bloxam), Basingstoke, Kent (Mr. R. 8. Hill). 
Dr. Nylander (in Mit.) says C. degenerans, Fr. L. 8. 54, has 
K—, and that C. coralloidea, Ach., which in his Lich. Scand. - 
p- 54, he regarded as a variety of degenerans, is identical with 
‘ muricata, Dél., and a variety of C. pungens (K+). All the 
degenerans of herb. Délise have K—,
