67. L. teichophila Nyl. ea Lamy, Bull. Soc.-Bot. Fr. t. xxv. (1878) 
p- 405.—Thallus subdeterminate, moderate, verrucoso-areolate, dark- 
greyish (K+ yellowish, CaCl—). Apothecia submoderate, plane, 
‘black, the thalline margin thick, entire or often subrugose ; spores 
ellipsoid, 0,018-25 mm. long, 0,011-16 mm. thick.—Cromb. Journ.

Also approaches ZL. confragosa in various respects, but differs in the 
darker thallus, and more especially in the larger, thicker spores. The 
apothecia are numerous and often crowded, with the thalline margin 
scarcely or but little prominent. 
Hab, On rocks and walls in maritime and upland situations.— Distr. 
As yet seen only from a few localities in Great Britain and Ireland.

68. L. coniopta Nyl. Flora, 1873, p. 19.—Thallus indeterminate, 
moderate or thickish, unequal, rimoso-diffract, brownish-grey or 
dark-brown (K —, K (CaCl)+reddish). Apothecia moderate, innate, 
black, at first plane, slightly margined, at length convex, immargi- 
nate, internally whitish; spores ellipsoid, slightly constricted, 
1-septate, brownish-black, 0,015-20 mm. long, 0,008-10 mm. thick ; 
epithecium brown, paraphyses moderate, subarticulate ; hypothecium 
colourless.—Cromb. Grevillea, i, p. 141; Leight. Lich. FL. ed. 3, 
p- 216.— Brit. Evs.: Cromb. n. 158. 
Closely allied to L. sciudes Nyl., a plant of the FE. Pyrenees, though from 
the evanescent thalline margin of the apothecia, which is visible only in 
their earliest stage of development, it has the appearance of a Lecedea 
allied to ZL. contops. The apothecia occur chiefly towards the centre of 
the thallus and are somewhat scattered. The spermogones are abundant, 
black, punctate, with spermatia thinly bacillar, 0,0045 mm. long, 0,005 mm. 
thick.
