Species of the Cladoniei by the action of Hydrate of Potash. 411 



Var. ochrochlora, Flk. (Nyl. Syn. i. p. 198) = Arnold;265; 

 Schter. 640; Anzi, C. C. 8; Coem. 1019; Hepp. 540; Coem. 

 CI. Belg. 54, 81, 82, 83, 84, 85, 86, 110; Mudd, Br. CI. 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, G, h) = Coem. 1020; Tuck. Am. Sept. 26 ; M.&N.644; 

 Coem. CI. Belg. 17; Wright, Cuba, 28; Sch^r. L. H. 458; 

 Mudd, Br. CI. 3. 



In my herbarium are also specimens from Untersontheim 

 (Kemler), and Barmouth, North Wales. 



Var. soboli/era, Del. (in Dub. Bot. Gall. p. 631) = Schser. L. H.. 

 62, 63, 274, 275 ; Tuck. Am. Sept. 27 ; Coem. CI. Belg. 14, 15, 

 16; Leight. Exs. 14; Mudd, Br. CI. 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. Coemans (Clad. 

 Achar.) regards verticillata as the type of the species, and cer- 

 vicornis (our soholifera) as a simple microphylline variety. The 

 true cervicornis has a reaction K+, which BeT^arates soholifera 

 (K— ), which has hitherto, from external aspect, been confused 

 and intermingled with it. Dr. Nylander [in litt.) informs me- 

 that C. cervicornis of Delise herb, has K + , and C soboUfera of 

 the same collection has K — . 



22. C. decorticata (Fr) (Nyl. Syn. i. 199) = Schser. 279 5 

 Hepp. 545; Anzi, C. C. 5; Coem. Clad. Belg. 21. 



This I possess also from Upsal (Dr. T.M. Fries), Dagero, Fin- 

 land (Abbe Coemans) . Distinct from cariosa (K + ) by reaction 

 K— , and (rom pywidata var. decorticata (Flk.) by the different 

 squamules. 



Dr. Nylander {in litt.) says C. decorticata (Fr.), Nyl. (of 

 which C. Mougeotii, Del., is a spermogoniferous state), has K— . 



23. C. degenerans, Flk. = Fr. L. S. 54 (fide spec, a Nyl.); 

 Richardson, Arct. Am. 19, 20, 21, 22, 23, 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, Vail. Gastern (Schseref), Leicestershire 

 (Rev. A. Bloxam), Basingstoke, Kent (Mr. R. S. Hill). 



Dr. Nylander {in litt.) says C. degenerans, Fr. L. S. 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, Del., and a variety of C. pungens (K + ). All the 

 degenerans of herb. Delise have K— ,
