STIRTON.—Lichens of Province of Wellington. 239 
filiform, densely matted together at their thickened apices; asci pyriform, 
lower extremity attenuated and easily detached, walls composed of a double 
hyaline membrane, with a broad intervening space resembling—in this respect— 
the epispore in Z. sanguinaria; spores large, four, six, or eight, oblong- 
cylindrical, multiseptate, with longitudinal septa. 
A remarkable phenomenon is seen in a microscopical preparation of this 
lichen of some months’ standing, viz, filaments are seen arising from many 
detached spores—first, from the extremities ; second, from the septa, or in a 
line with them. Whether this is the result of germination I cannot determine, 
as I have very few apothecia left and do not care to destroy more until I see 
whether it is possible to secure other specimens. 
A very distinct and curious lichen. 
On bark of trees, Tinakori Hills, Wellington. 
Lecidea insidens, Stirton. 
Thallus white, smooth, investing the leaves of Dicranum menziesii with a 
continuous layer, to which, also, the apothecia are attached by a central 
point; apothecia reddish brown, rugose, plane, surrounded by a smooth 
prominent border of the same colour; hypothecium pale red, grumous ; spores 
eight, colourless, spherical, muralilocular ; paraphyses discrete. 
The spores are muralilocular, and not merely coarsely granular, while their 
outline, when free, isin the great majority of cases circular, although a few 
are to be seen somewhat oblong. The paraphyses are thickened at their 
apiees, where they are of a brown colour and matted together. 
Wainuiomata, Wellington. 
Lecidea implicata, Stirton. 
Thallus white, smooth, thin, glaucous, rimulose (K—-C—) ; apothecia large, 
sessile, flat or somewhat convex, pale buff colour, pruinose, rugose, border 
smooth, somewhat inflexed; paraphyses distinct, filiform, densely matted 
together, and giving off lateral filaments ; hypothecium yellowish brown; 
spores eight, colourless, elliptical, large, coarsely granular. Disk of apothecia 
rendered slightly darker by K, but not red. This lichen has a proper margin, 
and as the apothecium is attached by a broad central basis, the thalline 
receptacle is seen covering it and the unattached portion, but ceases consider- 
ably below the proper margin. Spores 043 х :021mm.

Lecidea contigua, Fr. 
. А curious form growing on earth. The apothecia are sessile, and arranged 
in beautiful concentric rings; the border sharply defined and flat, being set at 
an angle to the surface—a disposition seen in a certain proportion of New
