BACIDIA] LECIDEACEa; 155 



11. B. carneoglauca A. L. Sm.— Thallus determinate, thin, 

 subleprose, glaucous-green (K-, CaCl-), limited at the circum- 

 ference by a white hypothallus. Apothecia minute, convex, 

 immarginate, pale- or dull-flesh-coloured ; hypothecium and 

 epithecium colourless ; paraphyses not well discrete ; spores 

 narrowly fusiform, 1-5-septate, 0,025-40 mm. long, 0,0030-35 

 mm. thick ; hymenial gelatine bluish then tawny-yellow with 

 iodine. — Lecidea carneoglauca Nyl. in Flora Ivi. p. 295 (1873) ; 

 Cromb. in Grevillea ii. p. 90 ; Leight. Lich. Fl. ed. 3, p. 366. 



Exsicc. Larb. Lich. Hb. without number. 



In our specimens the spermogoues alone are present ; they are 

 minute, ureeolate and flesh-coloured with a pale margin; spermatia 

 oblong, 0,004-5 mm. long, 0,0015 mm. thick. 



Hah. On siliceous rocks. — B. M. Bezel, Jersey (the only locality). 



12. B. chloroticula A. L. Sm. — Thallus effuse, very thin, 

 subleprose, greenish (K — , CaCJ— ). Apothecia very minute, 

 plane, margined, whitish-flesh-coloured, the margin whitish; 

 hypothecium colourless ; paraphyses not well discrete ; spores 

 thin, acicular, straight or slightly bent, 0,0020-35 mm. long, 

 00,01 mm. thick; hymenial gelatine wine-reddish with iodine. — 

 Lecidea chloroticula Nyl. in Flora Ix. p. 564 (1877); Cromb. in 

 Grevillea vi. p. 112 ; Leight. Lich. Fl. ed. 3, p. 254. 



Exsicc. Larb. Lich. Hb. n. 138. 



Closely allied to B. inundata, differing in the very minute pale- 

 coloured peziza-like apothecia. In our specimen the greenish thallus 

 spreads over the stone, and the apothecia are crowded in one small 

 group. The spores are faintly but quite distinctly pluri-septate, and 

 the slender arcuate spermatia measm-e up to 0,050 . mm. long, 

 0,0008 mm. thick. 



Hab. On mica-schist rooks in a stream in an upland situation. — 

 B. M. Mweelan, Connemara, Galway (the only locality). 



13. B. carneoalbens A. L. Sm. — Thallus greenish-glaucous, 

 thin, effuse, granulose (K-f- yellow, CaCl-)-red). Apothecia pale- 

 flesh-coloured, sometimes becoming partly dark-coloured, convex, 

 immarginate ; hypothecium colourless ; paraphyses concrete, 

 colourless at the apices ; spores elongate-fusiform, 3-7-septate, 

 0,023-27 mm. long, 0,0025-35 mm. thick ; hymenial gelatine 

 tawny-wine-red with iodine, especially the asci which are at first 

 blue at the tips. — Lecidea carneoalbens Nyl. in Flora lix. p. 307 

 (1876) ; Cromb. in Grevillea v. p. 26 ; Leight. Lich. Fl. ed. 3, 

 p. 366 



Near to B. inundata, but differs in the lighter-coloured apothecia 

 and in the form of the spores, which are straight and slightly 

 narrower at one end. The paraphyses are yellow in the mass. 



Hab. On water- washed rooks in a maritime district. — B. M. 

 Killery Bay, Connemara, Galway (the only locality).
