Campbell's Islands. | CRYPTOGAMIA ANTARCTICA. 87 
Dr. Montagne distinguishes this from the 8. carpoloma, Delise, by its having the apothecia on the surface, as 
well as on the margins of the frond, and by its different under surface. Our specimens are in a rather imperfeet 
state. 
The S. variabilis, Ach., is also enumerated by Montagne as a native of Lord Auckland’s group. 
8. PARMELIA, Ach. 
1. PARMELIA rubiginosa, Ach., Syn. Lich. p. 202. Lichen affinis, Engl. Bot. t. 983. 
Has. Lord Auckland's group and Campbell's Island; on the bark of living trees, also on the ground 
on the hills. 
A most variable plant and a very abundant one in New Zealand and Tasmania; on the hills the thallus is re- 
duced to a few imbricating scales, as in Syuamaria, and the apothecia are strangely contorted and closed, having the 
border closely inflexed ; in this state we are inclined to suspect that it passes into the Lecanora Hypnorum of these 
islands. 
2. PARMELIA sphinctrina, Mont. in Voy. au Pole Sud, Bot. Crypt. t. 15. f. 3. 
Has. Lord Auckland’s group; on the bark of trees. 
This, judging from our copious suites of Tasmanian and New Holland specimens, is hardly distinct from P. ru- 
biginosa. Montagne’s figure of it is excellent. 
9. LECANORA, Ach. 
1. Lecaxora Hypnorum, Ach., Syn. Lich. p. 193. 
Has. Campbell’s Island; upon tufts of Andreea and other mosses. 
The upright mode of growth and slender laciniz of the thallus, distinguish the present from its allies ; the spe- 
cimens are of a dusky yellow colour. 
2. Lecanora versicolor, Hook. fil. et Tayl.; substrato adnato tenui atro, thalli squamulis subrotundis 
planis crenulatis albidis demum flavis confertis levibus, apotheciis majusculis sessilibus concavis, disco 
nigro-pruinoso, margine integerrimo subincurvo. 
Has. Lord Auckland's group; on bark. 
Cespites 1 unc. late, nigro-limitatee, substrato continuze, fusce v. pallide virescentes. Apothecia squamis ma- 
jora, disco nigro-pruinoso, margine thallode crassiusculo. 
Allied to the Z. varia, but marked by the scattered apothecia, dark discs and smooth thallodal border. 
3. LECANORA tartarea, Ach., Syn. Lich. p.179. Engl. Bot. t. 156 et 1634. 
Has. Lord Auckland's group; on the ground. 
Specimens, apparently of this plant, are in a very imperfect state. 
4. Lecanora Parella, Ach., Syn. Lich. p. 169. Engl. Bot. t. 727. 
Has. Lord Auckland's group; on the hills. 
Also in a very rudimentary state.
