flat, or somewhat convex (K — C — ) ; apotliecia briglit yellow (K red), convex, 

 immarginate, generally clustered and then deformed j 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 (K — C — ) ; in another, of a darker dingier colour, rimulose-areolate, 

 areolte flat or convex and somewhat granulate. Apothecia elevato-sessile ; 

 concave and contracted in a young state, afterwards expanded and flat, or even 

 somewhat convex ; csesio-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, grumoixs, subtended by the dense black 

 receptacle. This is evidently allied to L. marginiflexa (Taylor), although quite 

 distinct.

Lecidea rtiacidosa, 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 -OOTmm; 

 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.

Melaspilea amphorodes, Stirton. 



Thallus dai-k ashy grey, rimulose, thin ; apothecia small, black, prominent, 



flat in a young state, and smooth, with a slight border ; convex immarginate 



and rugose, when mature. Section of apothecium pale throughout, seated on 



a brownish grumous stratum ; paraphyses scattered, distinct, colourless.
