or densely pilose, or pubescent. The degrees of division of the thalline lobes, which are 
usually more or less entire, are almost equally diverse.

1. On trees, East Taeri bush; on columnar basalt, Greenisland Bluff, Otago: W, L, L.: 
both forms sterile. "Thallus very isidiiferous, with much-curled margins. _ 
2. Sub nom. S. glabra, Tayl. (Fig. 18.) [Linds. Spermog. 201, plate x. figs. 13, 14.] 
Falkland Islands: Dr. Hooker, Antarct. Exped.: in my herbarium; in fruit, Spores 
broadly ellipsoid, 1-septate within their thecæ (a), 3-septate when old (b), pale brown or 
brownish yellow. Thecæ (a) largish, 8-spored, blue with iodine. Paraphyses discrete, 
delicate, filiform. 
3. In herbarium Kew: Cape Horn; Falkland and Auckland Islands: Dr. Hooker: 
on Plagiochila, springs, Mount Wellington, Tasmania. Plant sterile in most of these 
cases, and generally so: in fruit in Auckland-Island specimens, in which the thallus is 
decorticated in patches, exposing the white medullary tissue. In Falkland-Island 
specimens the thallus is irregularly sorediiferous, and its colour varies from pale straw- 
yellow to olive or brown. Were this form Scotch, it would probably be referred to 
Stieta scrobiculata, Ach., or Stictina limbata, Sm. 
The apothecia of S. Freycinetii are sometimes changed in appearance by the growth 
thereon of the black parasitic Celidium Stietarum, Tul. (Figs. 26, 27.) The deformity 
produced is the basis of variety Delisea, Bab. L. N. Z., and of the genus Delisea of Fée 
[Nyl. Syn. 365] *. 
Sp. 11. S. GRANULATA, Bab. (Fig. 19.) [Nyl. L. N. Z. 247, Stictina; Nyl. Syn. 340.] 
l. On trunks of dead trees, Greenisland bush, Otago: W. L. L.: sterile. On trees, 
Signal Hill, Dunedin, sterile ; Auckland, in fruit: Dr. Sinclair. 
Spores ellipsoid, or oval-oblong, brown, 1-septate, sometimes physcioid (a), as in 8. fos- 
sulata and S. physciospora ; *0006" to -0009" long, :0008" to :00045" broad. Thecæ 
8-spored, :0024” to -0030" long, 0009” broad. Paraphyses subdiscrete, apices closely 
aggregated, and concealed by brownish-yellow granular colouring-matter. Hymenmm 
blue with iodine, contains a large amount of free oil globules of all sizes. "Thallus usually 
sterile, glaucous, margins and surface more or less copiously covered with soredia, Of 
isidia, or both. The smaller forms are sometimes very elegant, the thalline segments 
fringed with copious marginal white soredia, or coralloid granulations. The plant j 
well named, if it is to be considered a separate species. The thallus is apt, like that 0 
other Sticte, to be infested with black parasitic maculiform Celidia*.
