Porm tuuiida Cromb. Grevillca, xi. (1S83) p. 114. — rodctia 

 turgid, veiitricose, the axils and apices dilated, infundibuliform. 



This is analogous to form vcntricosa of C. squamosa, with wliich but 

 for the reaction it might readily be confounded. It is apparently but 

 rarely fertile. 



Hab. On moist shady rocks among mosses in uplaud tracts. — Dixfr. 

 Local and scarce in 8. England, X. ^^'ales, S. Scotland, and in the S.W. 

 Highlands. — B. M. : High Rocks, near Tunbridge Wells, Kent ; Dulgelly, 

 Merionethshire. New (xalloway, Kirkcudbrightshire ; Karcaldine, Argyle- 

 shire. 



28. C. asperella Cromb. Grevillea, xi. (18S3) p. 114.— Thallus 

 si|uamulose at the base, the squamules minute, inciso-crcnate, siib- 

 evanescent ; podetia elongate, slender, erect, Avhitish or greyish- 

 white, glabrous, squamulose or furfuracoo-pulverulent, proliferously 

 and variously branched, the axils and apices pervious, denticulate 

 (K— , CaCl — ). Apothecia small, conglomerate, brown. — Ckchmia 

 s(/iiamosa /5. asperella Florke, Clad. (1828) p. 132: Mudd, Brit. 

 Clad. p. 20. — To this fide Xvh is referable also Cenorm/ce sjjeciosa 

 Del. in Dub. Bot. GaU. ii. p. G26.— i?/77. E.rs. : Mudd, Clad. n. 41. 



From subspecies C. adspersa, which it closely resembles, this differs in 

 the erect podetia and their fasciculate branches, which are subidate or 

 truncate at the jipicea. It may thus with propriety be regarded as a 

 distinct species rather than as a subspecies of C. squamosa. In the wry 

 few British specimens the podetia, which are 2-3| in. long, are sparm;^ly 

 foliiferous throughout, with the apothecia rarely present. 



Hab. Among mosses on rocks and heaths in upland districts. — Disfr. 

 Apparently very local and scarce in N. England. — B. M. : Stogdale, Cleve- 

 land, Yorkshire. 



Form polychonia Cromb. Grevillea, xi. (1883) p. 114. — Podetia 

 glabrous and fui'furaceo-pulverulent, the axils dilated and radiato- 

 proliferous. — Cladonia squamosa i. polyclionia Florke, Clad. (1828) 

 p. 136 ; Mudd, Brit. Clad. p. 20.— Brit. Exs. : Mudd, Clad. n. 42. 



Differs in the absence of any folioles (m the podetia (except occasionally 

 towards their base) and in the form of the axils. The aputhecia are very 

 rare. 



Hab. On the ground in upland heaths. — Disfr. Rare and local in X. 

 England; probably to be detected elsewhere. — B.M.: Baysdale, Cleve- 

 land, Yorkshire. 



29. C. cSBSpititia Florke, Clad. (1828) p. 8.— Thallus squamulose- 

 foliaceous at the base ; leaflets small, ascending, laciuiato-lobed, 

 erenate or eroso-lacerate at the margin, densely ccespitoso-congested, 

 pale-green above, white beneath ; podetia veiy short, naked, cylin- 

 drical, simple or divided, pale (K — ,CaCl — ). Apothecia conglo- 

 merate either on the podetia or on the leaflets, flesh-coloured or 

 reddish; spores 0,009-1(3 mm. long, 0,004-5 mm. thick. — Cromb.
