Lichenes, by Babington $ Mitten.] FLORA OF TASMANIA. 347 
Has. Earth-banks, among Mosses; also on trees; various collectors. 
Dr. Taylor has referred some specimens to his P. perlata, others to his P. reticulata. 
2. Parmelia saxatilis (Ach. Syn. Lich. p. 203; Bab. l.c. p. 285).—P. tenuirima, Tayl.! Lich. 
Antarct. n. 11. P. sulcata, ejusd. n. 68. 
Has. Among Moss, on Fagus-trunks, elev. 2000 feet; also on granite rocks, Launceston, Gunn. 
Collected also by Hooker, etc. Fertile. 
Some of Mr. Gunn's specimens are very fine, but are certainly only a form of P. sazatilis, Ach., i. e. of P. sul- 
cata, Tayl.! Other specimens are more like the ordinary state of the plant, and are named P. sulcata by Dr. Taylor 
himself. 
3. Parmelia physodes (Ach. Syn. Lich. p. 218; Bab. l. c. p. 286). 
Var. B. enteromorpha, Tuck. Syn. N. Amer. Lich. p. 28.—P. enteromorpha, Ach. et Auctt. 
Has. On trees, ete., fertile, Gunn, Archer. 
Both the Acharian species occur, and that under various forms, some of which simulate the appearance of 
Evernia prunastri. 
4. Parmelia diatrypa (Ach. Syn. Lich. p. 219; Bab. l.c. p. 286). 
Haz. On trunks of trees, Gunn (on Fagus). Cheshunt, Archer, efe. Fertile. 
5. Parmelia tiliacea? (Ach. Syn. Lich. p. 199; Bab. l.c. p. 285). 
Has. On trees: Cheshunt, Archer. 
Rather different from the European form, but substantially agreeing (as it appears to me) with Tuckerm. Lich. 
Am. Exs. n. 70. Dr. Hooker appears to have found the same plant on Mount Wellington. 
6. Parmelia placorodioides (Nyl.! Enum. p. 104). 
Haz. On rails, “very common,” Oldfield. But very few specimens have been collected. 
The specimens are named by Dr. Nylander. A perplexing species, almost intermediate between P. tiliacea 
and P. physodes. The habit is that of P. tiliacea, but the structure of the thallus more resembles that of P. physodes. 
We know not whether Dr. Nylander has described the species. P. placorodia, Ach., Tuckermann ! Lich. Am. Exs. 
n. 71, is also extremely near to it. 
7. Parmelia olivacea (Ach. Syn. Lich. p. 200; Bab. l.c. p. 286). 
Has. Rocks: Richmond, Oldfield. Collected also by Hooker. 
8. Parmelia conspersa (Ach. Syn. Lich. p. 209; Bab. l.c. p. 286).—P. Tasmanica, Zayl.! Lich. 
Ant. n. 70. 
Has. Rocks: also on dead timber; apparently common, Gunn, Hooker, Archer, Oldfield. 
See my remarks on this species in the ‘ Flora of New Zealand.’ 
9. Parmelia moniliformis (Bab. l.c. p. 288. t. 127; Nyl. Enum. p. 104). 
Has. Dry rocks: Grass-tree Hill, Hooker, barren. Cheshunt, on wood, Archer, barren. Very 
sparingly collected. 
A rare and little-known species, rightly placed by Nylander under the “ stirps P. colpodis.” 
10. Parmelia caperata (Ach.; Fries, Lich. Eur. p. 69). 
Has. Trees, rotten wood, and stones, various collectors. Fertile. | 
Almost a cosmopolitan, as it would appear from Dr. Nylander’s enumeration and our own herbarium, but not 
included in the ‘ Flora of New Zealand.’ This is the P. rutidota, Tayl.! Lich. Ant. n. 72, which differs in no respect 
from the European form, except that the thallus is thicker than usual (resulting from exposure?) and nigropunctate
