Yar. /3. deterininata Cromb. Grevillea, xviii. (1880) p. 44. — 

 Thallus niierophylliue, paler, livid, creuato-Iobate. Apothecia small, 

 the margin yi'llow-testaceous ; spores deteiminately 1-septate, 

 brownish, 0,02(5-36 mm. long, 0,007-8 mm. thick. — Pannaria car-

 naria muscoTHm var. ddcrmiaaia Xyl. Scand. (1861 ) p. 128 ; Cromb.

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. Ou moist soil in upland districts. — Distr. Apparently verv local 

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



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

 Thallus thiu, adnate, minutely grauuloso-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 (aud the thecte) bluish with iodine. —

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

 spores, 'i'he 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, aud 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. 



Hah. On decayed mosses in alpiue situations. — DiMr. Extremely local 

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

 the Mts. of X.W. Ireland (Connemara, Galway). — B. ^I. :' Ben Lawers 

 Perthshire.' 



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

 Xyl. Syn. ii. p. 41. — Thallus monophyllous or submonophy Ileus, 

 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 sperm atia. 



Intimately allied to Pannaria, but differs in the type of the thallus aud
