558 KEY. J. M. CROMBIE ON THE LICHENS OF 



F. 10. Coralloides scyphis gracilibus tubiformibus, Pedicularis 



folio, p. 85. A 



m 



u megaphylla^ Coem. Sterile. Not distinguished, except by 

 Hudson, Fl. Angl. ii. p. 552, s. n. Lichen filiformis, from the 



following. B 



(Sm.\ Of this there 



is no specimen in hb. Dill. ; but as he describes the plant as 

 having the apothecia " exilia, coccinea," it is no doubt referable 

 to this form ; and has been correctly identified by Fries. 



F. 11. Coralloides scyphis humilibus, intusfuscis, p. 86, = Cia- 

 donia fimbriata f. exilis (Ach.). The specimen figured is 

 broken up into fragments, upon which only two or three almost 

 sessile apothecia are visible. Rightly distinguished by Acharius 

 in Meth. p. 338, s. n. Bceomyces pyxidatus, /3 exilis, the name 

 pygmcea given it by Fries in Index Dill, being consequently 

 superfluous. 



F. 12. Coralloides scyphiforme, foliis alcicorniformibus cartila- 

 ginosis, p. 87. A=Cladonia alcicorjtis (Lghft.). The speci- 

 men in hb. Dill, is infertile, the one figured with apothecia having 

 been taken from some other source. B = Cl. cekvicor:nis (Ach.). 

 Two specimens, infertile. Hitherto not rightly identified, having 

 been included by Lightfoot under the preceding, and referred by 

 Acharius in Meth. p. 350, to his var. cladomorpha. C = Cetea- 

 kia Delisei *fastigiata, Bel. Sterile. This has not previ- 

 ously been determined. D = Ciadonia squamosa f. cucullata 



{Del.). Infertile. Now for the first time identified. 



F. 13. Coralloides scyphiforme serratum elatius, caulibus gra- 

 cilibus glabris, p. 88. A, B = Cladonia gracilis (hybrida), 

 Ach. Fertile. C, D = Cl. gracilis f. chordalis, Flk. Sterile. 

 Both of these have for the most part been rightly determined by 

 authors. E=Cl. crispata f. cetrarijiformis {Del) ( = Cl.fur- 

 cata f. subcrispata, Coem. Clad. Belg. n. 200). Sterile. Eeferred 

 by Acharius to his var. cladonioides of Cladina amaurocraa, with 

 which it has nothing in common. 



Series II. Species with imperfect scyphi. 



Tab. XV., Dill. Hist. Muse. 



F. 14. Coralloides vix ramosum, scyphis obscuris, p. 90. A 

 Cladoxia macilenta, Hffm. Fertile. The specimen figured has 

 the apothecia denigrate in hb. Dill. This is the Lichen cornutus
