CLADONIA. | CLADONIET. 169 
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.—Beomyces scolecinus 
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. 53) erroneously describes as “brown,” are apparently 
extremely rare; so that the plant is generally spoken of as sterile. 
Hab, On old decaying pales and dead wood of trees in lowland and 
upland tracts.—Distr. Local and scarce in 8. and Central England.—

Var. 3. scabrosa Nyl. ew Lamy, 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.—Cladonia coc- 
cifera e. macilenta e. scubrosa 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 3 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, 
Hab. On putrid stumps and on turf-walls in wooded upland tracts.— 
Distr, Local and scarce in 8., W., and N. England and N. Wales, 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.— Oladonia 
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. 
Hab. On turf-walls in shady upland situations.—Distr. Found only 
among the Central and N. Grampians, Scotland.—B. M.: Rannoch, 
Perthshire ; near Inverey, Braemar, Aberdeenshire. 
Var. y. coronata Nyl. Lich. Scand. (1861) p. 62.—Thallus
