Genus XXII. Squamaria. (Plate LXII.) 
Sp. 1. S, GALACTINA, Ach. (Figs. 15, 16.) And var. dispersa, Pers. 
On porphyritie basalt, Forbury Head; on basalt, south peak of Saddle-hill, Otago: 
W. L. L.: associated with Lecanora pyracea and L. vitellina. Apparently athalline ; 
apothecia frequently irregular in outline and size; disk waxy, pale buff to dark slate- 
colour; margin thick or thin, entire or crenulate—in the latter condition, especially, 
resembling crenulate forms of Lecanora wmbrina (Lichen crenulatus, Dicks., non Pers., 
Nyl. L. Scand. 162). 
Spores ellipsoid or oblong-ellipsoid, simple, colourless, ‘0003” long, “00025” broad. 
Thecæ 8-spored, 0020" to -0024/ long, 0006" broad. Paraphyses indistinct; tips closely 
aggregated, obscured by granular, brownish, or brownish-yellow colouring-matter. Hy- 
menium blue with iodine; constituents somewhat indistinct. 
Genus XXIII. Lecanora. (Plate LXII.) 
Sp. 1. L. curysostiora, Tayl. (Fig. 17.) [Nyl L. N. Z. 252. | 
On trees, East Taeri bush, abundantly in fruit; on branches and twigs of living trees 
and shrubs, Stoney-hill bush, Otago: W. L. L. A beautiful plant, one of the finest 
Lecanore of New Zealand. 
Spores (c, d) oblong-ellipsoid, colourless or pale yellow, muriform or granular, 0030” to 
0045” long, 0009” to 0015” broad. Thecæ (a, b) 1-spored, deep blue with iodine, especi- 
ally at their apex, 0045” long, ‘00127 broad. Apothecia in normal condition, with a flat 
(sometimes suburceolate) disk, of an orange-red tint, liable to become difform with age, 
disk falling away, and leaving the whitish hypothecium, which is concolorous with the 
thallus. The thallus is one of those subtartareous ones likely to occur variolarioid. The 
plant generally resembles various forms of Lecanora parella, tartarea, and subfusca, 
from which, however, it is distinguished by the character of its spores. It is “sk 
ously the same plant which is figured by Massalongo as Myxodictyon chrysosticta or 
N. Z.* plate i.; Lecanora, Tayl. Lich. Antarct. 50; Parmelia, Bab. L. N. Z. 29). The 
thecæ are represented as large and 1-spored ; the spores as large, muriform in the ma- 
ture, and simple in the young, state.
