Form 3. scolecina Xyl. Licli, Scand. (1801) p. G2. — ThaUiis 

 with the hasal sqiiainulcs miiiuto, greyish, partly grauulose or gra- 

 niiloso-dissolved : podetia vciy short, somewhat ventricoso-suhulate, 

 greyish- gramilose. Apotliecia minute, solitary or 2-3-aggregate, — 

 Cromb. Lich. Brit. p. 21, Grcvillea, si. p. 11-4. — Bieomyces scoJecinvs 

 Aeh. Meth. (IbUa) p. 324, t. 7. f. 2. 



A well-marked form distinguished by the short podetia (2-3 lines in 

 height) and by the granulosa squamules. The apothecia, which Acliarius 

 (Lich. Univ. p. 543) erroneously describes as " brown," are apparently 

 extremely rare ; so that the plant is generally spoken of as sterile. 



Hah. On old decaying pales and dead wood of trees in lowland and 

 upland tracts. — Dish: Local and scarce in S. and Central England. —

Yar. /). scabrosaXyl. f.vLamy, Bull, Soc. Bot. Fr. t. xxv. (1878) 

 p. 357. — Thallus granuloso-squamulose at the base; squamules 

 greyish or glaucous, beneath white ; podetia short, cylindrical, 

 simple or short and variously divided above, ascyphous, greyish- 

 white or glaucous, entirely granuloso-rugose. Apothecia small, 

 discrete or confluent. — Cromb. Grevillea, xi. p. 115. — CJadonia coc- 

 cifera e. macilenta e. scahrosa Mudd, Brit. Clad. (1865) p. 32. — 

 Brit. Exs. : Mudd, Clad. n. 73. 



Well characterized by the crowdedly rugose basal and podetial squa- 

 mules, which give it a peculiarly scabrid appearance. The podetia are 

 from ^ to I in. long, of moderate thickne>s, and often divided towards 

 the apices. In the simple podetia the apothecia are rarely present ; but 

 in those more divided they are frequent and numerous. 



Hob. On putrid stumps and on turf-walls in wooded upland tracts. — 

 Disfr. Local and scarce in S., W., and N. England and N. AVales, but more 

 frequent among the Scottish Grampians ; not seen from Ireland. — B. M. :

Form intumescens Cromb. Grevillea, xv. (1886) p. 46. — Podetia 

 more elongate, turgid, densely and coarsely granulato-squamulose, 

 simple and rarely obscurely scyphiferous at the apices. — Cladonia 

 nuicilenta form ina-assata Cromb. Grevillea, xii. p. 92, 



Differs in the much thicker podetia, which ai'e from | to 1 in. in length. 

 They are also occasionally obscurely scyphoid at the apices, the scyphi 

 being coarsely granular within. \Yhen present the apothecia are minute 

 and discrete.

 among the Central and N. Grampians, Scotland. — B. M. : Rannoch,
