squainulose-furfuraceous ; fertile podetia stout J — ^ in. in 

 height, bearing 3 — 10 brown, or reddish-brown, crowded 

 fruiting tubercles. Sterile podetia abruptly acuminate, 

 furfuraceous, paler. Squamules and podetia with K very 

 deep yellow. 



6. C. delicata, Flh. (K + C— ) 



Thallus caaspitose, microphylline, white or brownish-grey, 

 leaflets minute, eroso-laciniate, laciniaj narrow, minutely 

 incised or crenate, and granular on the margins ; podetia 

 slender, simple or divided, £-in., thickened upwards, cartila- 

 W ginous, glabrous, longitudinally ribbed or fissured, more or 

 less with granular scales. Separated by its chemical reaction 

 from C. pityrea, C. casspititia, and C. squamosa, to each of 

 which it has close affinities. 



Syn. — Scyphophorus parasiticus, Hook ; Cenomyce para- 

 sitica, Mack. ; C. squamosa v. delicata, Mudd. ; C. pityrea 

 v. delicata, Leigh. Leighton's Lich. Fl. G. Brit. p. 58. 



7. C. squamosa, Hoffm. (K — C — ) 



Thalline squamules, often small, and narrowly lacinulate. 

 Podetia caaspitose, white, glaucous-granulose or squamulose; 

 fertile ones cylindrical, 2 in. high, erect, repeatedly branched, 

 prolif ei ously denticulate or subulate from the margins of the 

 minute irregular scyphi ; apices rigid, sub-corymbose, 

 radiato-cristate , glabrous, longitudinally sublacunose, cortex 

 entire, clothed with minute leaflets or scales. Sterile 

 Sn. podetia rarely subulate, usually symphcarpeoas or cymose. 

 Apothecia pale or red-brown. Spermagonia terminal, deep- 

 brown, barrel-shaped, the ostiole spherical and distinct under 

 the lens; spermatia straight, in myriads, on digitate sterigmata. 



8. C. furcata, Hoffm. (K— C— ) 



Thallus minute, crisped lacinulate, rarely conspicuous. 

 Podetia aphyllous or squamulose, pale green, white, glau- 

 cous or brownish green, glabrous, branches attenuato- 

 Sn. subulate, divergenti-furcate ; cylindrical podetia fruticulose, 

 sub-dichotomously ramose ; axils and fertile extremities 

 sub-perforate ; fertile extremities sub-corymbose ; sterile
