Yar. j3. deterininata Cromb. Grevillea, xviii. (1889) p. 44. 

 Thallus microphylline, paler, livid, crenato-lobate. Apothecia small, 

 the margin yellow-testaceous ; spores determinately 1-septate, 

 brownish, 0,0'26-36 mm. long, 0,007-8 ram. thick. Pannaria car- 

 nosa var. determinate Leight. Lich. Fl. p. 169, ed. 3, p. 156. Pan- 

 naria musconnn var. deterininata Xyl. Scand. (1861) p. 128 ; Cromb. 

 Lich. Brit. p. 43. 



Differs in the less developed thallus (resulting probably from the hab- 

 itat) and in the regularly septate, larger, brownish spores, which some- 

 times present several spurious septa. 



Hab. On moist soil in upland districts. Distr. Apparently very local 

 and rare in N.E. Ireland. B. M. : Carulough, co. Antrim. 



8. P. delicatula Nyl. ex Cromb. Journ. Bot. 1882, p. 274. 

 Thallus thin, adnate, minutely grannloso-crustaceous, brown. Apo- 

 thecia biatorine, small, somewhat convex, immarginate, brownish- 

 black (reddish when moist) ; spores fusiformi-vermicular, straight 

 or substraight, 7-9-septate, 0,040-76 mm. long, 0,005-7 mm. thick ; 

 paraphyses yellowish-brown at the clavate apices, hypothecium 

 colourless ; hymenial gelatine (and the theca?) bluish, with iodine.

A minute but very distinct species, well characterized by the peculiar 

 spores. The thallus is more or less adnate, closely appressed to the sub- 

 stratum, and scarcely visible except in wet weather. The apothecia, 

 which, though small, are large in proportion to the size of the granules, 

 are either scattered or crowded, and when moistened are of a bright wine- 

 red colour. Originally included by Th. M. Fries among the Collemacei, it 

 is entirely referable to this genus. 



Hab. On decayed mosses in alpine situations. Distr. Extremely local 

 and scarce among the S. Grampians, Scotland, and (Jide Nyl. in lift.) on 

 the Mts. of N.W. Ireland (Connemara, Galway). B. M. : Ben Lawers, 

 Perthshire. 



58. COCCOCARPIA Pers. in Gaudich. Yoy. Uran. (1826) p. 206; 

 Nyl. Syn. ii. p. 41. Thallus monophyllous or submonophyllous, 

 lobato- or laciniato-divided at the circumference. Apothecia biato- 

 rine, adnate : spores ellipsoid or oblong, simple, small ; hymenial 

 gelatine variously tinged with iodine. Spermogones with short, 

 cylindrical spermatia. 



Intimately allied to Pannaria, but differs iu the type of the thallus and
