Also approaches L. cotifrar/oxri 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. — Disfr. 

 As yet seen only from a few localities in Great Britain and Ireland. —

 moderate or thickisb, unequal, rimoso-diti'ract, brownish-grey or 

 dark-brown (K — , K (CaCl) -[-reddish). Apothecia moderate, innate, 

 black, at first plane, slightly margined, at length convex, imraargi- 

 nate, internally whitish ; spores ellipsoid, slightly constricted, 

 ] -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. 210. — Brit. Exs. : Cromb. n. 158. 



Closely allied to L. sciades Xyl., a plant of the E. 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 Lecidea 

 allied to L. coniops. The apothecia occur chielly towards the centre of 

 the thallus and are somewhat scattered. The spermogones are abundant, 

 black, punctate, with spermatia thinly bacillar, 0,0045 mm. long, 0,00o mm. 

 thick. 



Hab. On gneissic and granitic rocks in maiitirae districts. — Disfr. Local, 

 though plentiful, in the Channel Islands, S."\V. England, and N.E. Scot- 

 land. — B. M. : La Moye, Island of Jersey. Near Penzance, Cornwall. 

 Near Portlethen, Kincardineshire.
