Genus XVII. PANNARIA. (Plate LXII.) 
Sp. 1. P. LeucostIcTA, Tuck. (Fig. 11. [Nyl.L.N.Z. 250.) 
In crevices of mica-slate, Glen Martin, Chain-hills, in fruit, associated with Verru- 
caria pallida, Ach.; on boulders of tertiary quartzose grit, base of Saddle-hill, Otago, in 
fruit: W.L. L 
Spores ellipsoid, simple, colourless, :0006" long, 00025” broad. Thecæ 8-spored, 
0030” long, 0006” broad. Paraphyses subdiscrete, with slightly brown, tuberculiform 
heads. Hymenium pale blue, sometimes wine-red, with iodine. Apothecia sometimes 
sunk in the squamulose thallus, sometimes sessile and prominent, generally with a 
convex or turgid disk. Thallus varying in colour from grey to lurid; in the former case 
the apothecia are distinct, in the latter obscure. The plant has a general resemblance 
to P. brunnea, Sw. 
Sp. 2. P. xiGRA, Huds. [Nyl. L. N. Z. 250.] 
On tertiary “ Crag ” (made up of fragments of Ostrea, &e.), Woodburn, Saddle-hill, 
Otago: W. L. L.: in fruit. Spores indistinct. Paraphyses with dark-brown, granular, 
elosely-aggregated tips. Hymenium deep blue, constituents indistinet. The plant 
appears identical with Irish specimens in my herbarium (Carroll) very common on 
limestone in the Cork district, in fruit. Here also the spores are very indistinct, ellip- 
soid, varying from simple to 3-septate. 
Genus XVIII. CoccocARPIA. 
. Sp.l. C. MOLYBDÆA, Pers. [Linds. Spermog. 258.] l 
North Island, Colenso; sub nom. C. smaragdula, Pers. and Bab. L. N. Z. This 
is probably one of a few North-Island species which can hardly be looked for in the 
South Island, inasmuch as it is essentially a plant of warm or tropical countries, 1n 
Whieh, however, it is common and widely diffused. In herbarium Kew there "m 
cimens from Carissi (Lich. Amazonici, Spruce and Bab.), with nest Apre m : 
apothecia, exactly like those of the British C. plumbea, to which, indeed, C. mory 
has, at the least, a striking general resemblance.
