length bared of the buds represent all the characters of a Bc20myo.es. 

 In the dark brown disk opaque minute gongyli exist. Stipes solid, 

 yet less hard at the axis. 



4. B. anomalus. Thallus tartareous, areolate, brownish- 

 grey, edges of the areolae subcrenulate. Apothecia convex, 

 with a central depression, brown ; stipes immersed in the crust.

On stones in woods, and on rocks, County of Kerry ; common. 

 Thallus rather thick, cracked into areolae, pale brownish grey, some- 

 what greener when growing in shade ; of a fibrous or columnar struc- 

 ture ; the margin of a pale flesh colour. Patches sometimes occur 

 two or more feet in diameter. The surface of the areolae is rough, 

 with elevations and depressions. Apothecia when young immersed, 

 in which state they remain in shaded situations ; in more exposed, the 

 apothecia emerge, borrowing sometimes a spurious border from the 

 crust, but which is soon relinquished. On the centre of the apothecia 

 an umbilicus is commonly seen, as in others of this genus. The stipes 

 remains immersed in the crust.

5. Cenomyce. Ach. including Cladonia of Fee and Pvcno- 

 thelia of Dufour. 



Thallus cartilagineo-crustaceous, or foliaceous, laciniated ; 

 jjodetia fistulose, sometimes sterile ; apothecia hemispherico- 

 subglobose, terminal on the podetia, not bordered. 



a. Thallus somewhat shrubby, branches subulate. 



1. C. uncialis, Ach. Podetia aggregated, elongated, smooth, 

 cylindrical, of a pale yellowish-white ; the branches short, 

 patent; the axils perforated. Ach. L. Un.p. 55S. Eng. Bot. t.

a. common in the mountains. (3. on the side of Devis mountain, Mr. 

 Templeton. The var. /3. is very remarkable, perhaps distinct. It has 

 never the sulphur-yellow colour of a. but is brown, has a very consi- 

 derable thallus of minute lobed scales at the base of the podetia ; 

 these have sprinkled over their surface, brownish flattened granular 

 buds, that expand occasionally into minute white scales. 



2. C. rangiferina. Ach. Podetia erect, elongated, much 

 branched, cylindrical, of a slightly greenish-ash colour ; the 

 axils subperforated ; the ultimate branches deflexed ; apothecia 

 subglobose, brown, on small erect stalks. Ach. L. Un. p. 564.

On heaths and on mountains ; common. Podetia three to five
