when wet transparent pale-brown ; hypothecium black ; para- 

 physes thickish, coherent ; spores minute oblong, 0,009 mm. long, 

 0,002-3 mm. thick. — Biatora picila Massal. Misc. Lich. p. 38

The spores in the British specimens are larger than the size given 

 by Massalongo, measuring up to 0,012 mm. ; in the specimens 

 examined from Craig Tulloch and Twelve Pins, they are mostly simple 

 but occasionally 1 -septate. 



Hab. On rocks in upland regions. — Distr. Somewhat local and 

 rare in the Scottish Highlands and S.W. Ireland. — B. M. Craig

69. L. indigula Nyl. in Flora Ix. p. 563 (1877).— Thallus 

 effuse, thin, continuous, rugulose, whitish, often scarcely visible 

 (K — , CaCl — ). Apothecia small, subprominent, plane, thinly 

 margined, blackish, concolorous within ; paraphyses slender^ 

 colourless at the apices ; hypothecium reddish, the upper sub- 

 hymenial portion thick, blackish; spores ellipsoid, 0,013-16 mm. 

 long, 0,006-7 mm. thick ; hymenial gelatine pale-bluish then 

 wine-red with iodine. — Cromb. in Grevillea vi. p. 112; Leight. 

 Lich. Fl. ed. 3, p. 307. 



Related to L. sanguineoatra, but well separated from this and its 

 other British allies by the colour of the hypothecium above. In the 

 single small specimen seen, the apothecia are numerous, subminute, 

 at length convex and immarginate.

70. L. micrococca Nyl. in Flora Ixiv. p. 7 (1881). — Thallus 

 effuse, thin, leprose, dark or bright green (K — , CaCl — ). Apo- 

 thecia very minute, innato-sessile, subglobose, immarginate, pale- 

 yellow testaceous ; paraphyses conglutinate ; epithecium and 

 hypothecium colourless ; spores oblong or elongate-oblong, 

 simple or ? 1-septate, 0,009-12 mm. long, 0,003-4 mm. thick ; 

 hymenial gelatine bluish then tawny-wine-red with iodine. —

Closely related to Biatorina prasina, from which it is dis- 

 tinguished chiefly by the differently coloured and more globose 

 apothecia and by the simple spores. The Irish specimens seen are 

 for the most part well fertile. 



Hab. On decayed stumps of holly in a mountainous district. —
