82 LICHEN ES. Cenomijce. 



On dry banks ; not uncommon. A variety grows in Pigeon Island, 

 in the river Kenmare, tufted ; the lower parts of the podetia and 

 scales of the thallus of a tawny colour ; the cylindrical portions of the 

 podetia about one-fourth of an inch only in height, and covered 

 throughout with buds, expanding into thallodal scales of a greenish 

 grey colour. Mr. Templeton, on the contrary, has found at Bally- 

 gowan bog-, near Belfast, the var. 7. proboscidalis of Ach. L. Un. 

 which is at least five times as great in all its parts. 



12. C. gracilis, Ach. Scales of the thallus minute; podetia 

 elongato-cylindraceous, slender, suddenly expanding at the top 

 into toothed cups, bearing minute brown apothecia. C. ecmo- 

 cyna, var. 7. gracilis Ach. L. Un. p. 550. Eng. Bot. t. 1284. 



At Kilranelagh, County of Wicklow, Dr. Whitley Stokes. The 

 podetia are brownish, smooth to the naked eye, yet having buds on 

 the surface, which sometimes expand into a thallodal scale here and 

 there. 



13. C. filiformis. Thallus with minute, imbricated, suberect, 

 divided, and crenate scales ; podetia elongated, filiform, simple, 

 scaly, scarcely dilated at the top, bearing minute scarlet apo- 

 thecia. Lichen filiformis, Huds. Fl. Ang, p. 552. Eng. Bot. t. 

 2028. Cenomyce bacillaris Ach. Syn. p. 266. 



On the mountains, near Dunkerron ; common. In all the foreign 

 specimens I have seen, the colour was (I suppose through age) of a 

 dark brown. 



14. C. bellidifiora, Ach. Scales of the thallus scarcely any; 

 podetia thick, elongated, cylindraceous, rough with buds ex- 

 panding into thallodal scales, which are thickly set, laciniated, 

 and crenate, scarcely dilated above into cups ; apothecia convex, 

 conglomerate, confluent. Ach. Syn. p. 270. E. Bot. t. 1894. 



Near Belfast, on the mountains ; Mr. Templeton. The buds at 

 first swell into pale greenish-grey globules, which presently expand 

 into thallodal scales. The colour of the apothecia is described by 

 authors as scarlet, but in Mr. Templeton's specimens they are of a 

 dark purplish-brown, proving, with what has been observed of other 

 foregoing species, that the brightness of the colour of the apothecia is 

 little to be depended on in this genus as a discriminating mark. 



c. Thallus subcrustaceous. 



15. C. Papillaria, Ach. Thallus subcrustaceous, uniform, 

 granulated, greyish ; podetia erect, the young ventricose, 

 simple, smooth, the older branched, all of them white ; apo- 

 thecia globose, brown. Ach. Lich. U. p. 571. DiUen. t. 16, f. 

 28. 



On heaths, near Belfast, Mr. Templeton ; common in the South of 

 Ireland.
