CLADONIA] CLADONIACE 451 
2. Podetia mostly decorticate, usually scyphiferous and generally 
pervious. 
Basal squamules small, often evanescent. 
28. C. cenotea Scher. Lich. Helv. Spic. p. 35 (1823).— 
Primary thallus of a few usually small lobate-crenate squamules, 
or evanescent ; podetia of medium height, subcylindrical or 
irregularly turgescent, scyphiferous, repeatedly proliferous, the 
axils and scyphi pervious, whitish or greyish pulverulent 
throughout or partly corticate, and sometimes minutely squamu- 
lose at the base (K—, CaCl—). Apothecia small, brown or 
pale; spores 2-8 p long, 2°5-3°5 mw thick. — Cromb. in 
Grevillea xi. p. 113 & Monogr. i. p. 155. Bzeomyces cenoteus 
Ach. Meth. Lich. p. 347 (1805). 
The pulverulent podetia recall C. fimbriata, but it differs from 
that species in the pervious scyphi and axils; the repeated rather 
dainty proliferations of the scyphus give a branched appearance. 
Hab. On putrid stumps of trees and on the ground in wooded 
upland situations.—Dzistr. Local and scarce in N. England and 
among the Grampians, Scotland, in the old Caledonian Forest.— 
B. M. High Force, Yorkshire; Black Wood of Rannoch, Perthshire ; 
Ballochbuie Forest, Ballater, Aberdeenshire. 
Var. glauca Leight. in Ann. Mag. Nat. Hist. ser. 3, xviii. 
p. 414 (1866).—Podetia rather long, somewhat glaucous, rarely 
forming scyphi, the tips of the branches prolonged in subulate 
proliferations.—Cromb. in Grevillea xv. p. 45 & Monogr. i. p. 155. 
C. glauca Floerk. Clad. Comm. p. 140 (1828). 
Wainio has included as a growth form C. pywxidata var. fastigiata 
Floerke (tom. cit. p. 62), a form recorded by Mudd under C. pyxidata 
var. cornuta f. fastigiata (Brit. Clad. p. 13 (1965)) as ‘ podetia 
elongated, simple, the apex branched; branches short, attenuated, 
fastigiate,’’ and he suggests that here also should be placed C. squamosa 
var. polychomia f. ferulacea Floerk. (tom. cit. p. 137), quoted by Mudd 
as C. squamosa var. ventricosa, f. ferulacea (tom. cit. p. 20). 
Hab. On decaying stumps among mosses in mountainous districts. 
—Distr. Rare in N. Wales and (fide Crombie) in 5.W. Highlands of 
Scotland.—B. M. Rhewgreidden, Merioneth. 
29. C. squamosa Hoffm. Deutschl. Fl. ii. p. 125 (1795),— 
Primary thallus of short crenate somewhat wedge-shaped squa- 
mules, greyish-white or pale above, white beneath, sometimes 
evanescent ; podetia subcylindrical, usually scyphiferous, branched 
or proliferous, the scyphi and axils pervious, granulose and decor- 
ticate or unequaily warted, areolate-corticate, more or less covered 
with small squamules, the apices sometimes furcate or cristate 
when fertile (K —, CaCl —). Apothecia small, pale- or reddish- 
brown; spores 8-14 yp long, 3-4 pw thick.—Mudd Man. p. 56
