greenish powder of the surface had budded into lobed scales of consi- 

 derable size, towards the summits of the podetia. 



3 C. furcata, Ach. Podetia erect, elongated, much 

 branched, of a livid grey, dichotornous ; the axils imperforate ; 

 the branches, with the apices, divergent ; apothecia subglobose, 

 dark brown. Ach. L. Un. p. 560. Dillen. t. 16,/. 27. fl. subu-

On heaths and in the mountains ; «. common. 6. and y. near Bel- 

 fast, Mr. Templeton. I do not think the student is to expect to 

 find the varieties above given (in deference to authors) by any means 

 as strictly marked as the characters stated would seem to imply. 



b. Thallus foliaceous and scaly. 



4. C. parasitica. Scales of the thallus minute, eroso-laci- 

 nulate, glaucous-green, granulato-pulverulent; podetia dilated 

 above, slender, subdivided at the top ; apothecia conglomerate.

 catus, Eng. Bot. t. 2052. 



On the edges of dry turf, on heaths, on decaying timber ; common. 

 The apothecia are brown, convex, and dimpled on the summit, as in 

 the genus Boeomyces. White granular buds, sprinkled over the sur- 

 face of the podetia, are observed at length to expand into thallodal 

 scales. A variety occurs on mud walls, near Kenmare, with the scales 

 so densely covered with greenish grains as to form a continuous sur- 

 face ; the apothecia are nearly sessile, and have their border studded 

 with green grains strongly simulating a Lecanora. 



5. C. ca?iosa, Ach. Scales of the thallus minute, rotundate, 

 irregularly incised, subcrenate ; podetia whitish, rough with 

 granular buds, subdivided above ; apothecia conglomerate, of a 

 dark purple. Ach. Lich. Un. p. 567. Cladonia cariosa, Eng. 

 Bot. t. 2761. 



On dry banks, near Bantry, Miss Hutchins. Not unlike the pre- 

 ceding, of which it may prove only a variety j yet the scales are more 

 rotundate, and far less incised. 



6. C. sparassa, Ach. Scales pinnato-multifid ; podetia cy- 

 lindrical, branched, of a brownish grey, rough with buds ex- 

 panding into scales, terminating in cups, which are minute, 

 pervious, and proliferous ; apothecia clustered, brown. Ach. 

 Syn. p. 273. Eng. Bot. t. 2362. 



On rocks in the mountains, near Dunkerron ; not uncommon. The 

 figure of English Botany is deficient of the proper scales of the thallus, 

 and gives only those that germinate from the buds on the podetia. 

 Those scales are sometimes one quarter of an inch in length, incised in 

 a pinnate manner, the lacinise linear; they are of a pale dull green above, 

 and white beneath. The podetia, where they are not covered with the
