Form 3. scolecina Nyl. Lich. Scand. (1861) p. 62. Thalius 

 with the basal squamules minute, greyish, partly granulose or gra- 

 nuloso-dissolved ; podetia very short, somewhat ventricoso-subulate, 

 greyish-granulose. Apothecia minute, solitary or 2-3-aggregate. 

 Cromb. Lich. Brit,, p. 21, Grevillea, xi. p. 114. Bcromyces scolecimis 

 Ach. Meth. (1803) p. 324, t. 7. f. 2. 



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

 height) and by the granulose squamules. The apothecia, which Acharius 

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

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



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

 upland tracts. Distr. Local and scarce in S. and Central England.

 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. Gladonia coc-

 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 j to \ in. long, of moderate thickness, 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. 

 Distr. Local and scarce in S., W., and N. England and N. Wales, but more 

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

 Eppiug Forest, Essex ; Ardingly, Sussex ; near Bodmin, Cornwall ;

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 

 macilenta form incrassata Cromb. Grevillea, xii. p. 92. 



Differs in the much thicker podetia, which are from \ to 1 in. in length. 

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

 being coarsely granular within. When present the apothecia are minute 

 and discrete. "

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