Thallus maeular, umbrine-brown or umbrine- blackish, 
thin, subcontinuous or obsoletely rimulose, usually surroun- 
ded by a lead-coloured subphumoso-radiating hypothallus; 
apothecia black, lecideoid, minute, adnate, submargined, 
spores 8 ne, brown, ellipsoid, 1-septate, 0'010—11 mm long, 
0:006—7, mm thick, epithecium brown, hypotheeium colourless. 
Apparently allied to L. griseo-fusca, Nyl., but diffe- 
ring in the character of the thallus, the smaller spores, &e.

Thallus dark olive-greyish, continuous, unequal, variously 
rhagadiosely fissured; apothecia reddish flesh-coloured, innate, 
concave or plane; thec® myriospored, spores oblongo-baeil- 
lar, about 0'0035 mm long, about 00010 mm thick, para- 
physes slender, hymenial gelatine tawny wine-red with iodine. 
A peeuliar species, allied to L. rufeseens (Borr). On 
moist sandstone rocks at Whitehaven in Cumberland (Rev.

5. Pertusaria spilomanthodes, Nyl. in Flora 1881, p. 179, 
Thallus greyish, rugoso-unequal, rimoso- diffraet (K. +

6. Leeidea rhypodiza, Nyl. in Flora 18831, p. 5. 
Thallus brownish-black, thin or very thin, subgranulated,

Belongs probably to the section of Leeidea lentieu- 
laris, though in the absence of the spermogones this. is 
somewhat uncertain, P 265
