flat, or somewhat convex (K —C—) ; apothecia bright yellow (K red), convex, 
immarginate, generally clustered and then deformed ; hypothecium pale ; 
spores eight, straight or curved, colourless, elongato-elliptical, almost sub- 
cylindrical, one-septate ; paraphyses indistinct, with reddish brown apices, 
This lichen is peculiar in having attached to the hypothecium, or indeed 
forming part of it, little cushions composed of green granular matter, not 
gonidiac cells, but rather as if their granular contents were set-free granular 
gonima, in fact ; so that a microscopic preparation capable of showing the asci 
and spores has, to the naked eye, a bright lemon colour throughout. .I cannot 
see the slightest trace of a margin even in very young apothecia, and, as the 
reaction is always as indicated above, I have no doubt this lichen is distinct, 
although it has certain affinities to L. ehrhartiana (Ach).

Lecida campylospora, Stirton. 
Thallus, in one specimen, white or greyish white, thin, continuous, almost 
papery (К—0—) ; in another, of a darker dingier colour, rimulose-areolate, ` 
areole flat or convex and somewhat granulate. Apothecia elevato-sessile ; 
concave and contracted in a young state, afterwards expanded and flat, or even 
somewhat convex ; czsio-pruinose border thick, rounded, and inflexed ; spores 
four, six, or eight, colourless, very large, bent at middle, one-septate with— 
in many instances—nuclei in the loculi, epispore crenulate ; paraphyses dense, 
capillary ; hypothecium pale yellow, grumous, subtended by the dense black 
receptacle, This is evidently allied to Z. marginiflexa (Taylor), although quite 
distinct.

Lecidea maculosa, Stirton. 
Thallus whitish, thin, determinate, continuous or slightly rimulose, some- 
what rugulose (Ky Cy) ; hypothallus black ; apothecia black, sessile, flat, 
moderate, separate or conjoined, with a prominent black margin ; spores eight, 
colourless, the great majority curved, ellipsoid, one-septate ‘016 x 007mm ; 
paraphyses slender, distinct, with black, very much enlarged, club-shaped 
extremities, which are matted together; thalamium pellucid ; hypothecium a 
beautiful reddish brown, subtended by a pale stratum which rests on the black 
entire exciple.
