Hab. Joliiiiiy’s Creek, Back Eiver Gully, etc., Oldjield. Chesliunt, on wood. Archer.
Specimens not fully grown, but evidently belonging to this species.
7. S tic ta Rich ard i (Mont.! FL Fern. n. 7 9 ; Bab. I.e.).
Hab. Among Mosses, Gunn.
Verj' near the following.
8 . S tic ta fo v e o la ta (Delise, Stict. p. 101. t. 8 . f. 36; Bab. I.e .).— (Tab. CXCVIII.)
Hab. On trees in dense forests, Gunn. Springs, Mount Wellington, on branches of trees, alt. 2300
feet, Oldfield, Hooker.
Some specimens belong to my a Flotowiana, others to my y Billardieri.— P l a t e CXCVIII. Fig. 1 , portion
of frond and apothecia; 2, back of ditto; 3, portion of apothecium; 4, sporidia:—all magnified.
9. S tic ta F r e y c in e tii (Dehse; Bab. I.e.).
Hab. On wood, among Mosses, etc.; also running over live Ferns, Archer. Everywhere, all collectors.
The specimens mostly belong to my var. 0 Belisea. Mr. Gunn finds beautiful specimens in forests of Fagus,
at au elevation of 2000 feet.
10. S tic ta granulata (Bab. I.e .).— (Tab. CXCVII.)
Hab. Cheshunt, fertile, Archer. Collected also by Hooker aud Gunn, but their specimens are barren.
Tliis plant occurs also in Java, accordmg to my learned friends Drs. Montagne aud Van der Bosch.—P late

showing cjqiheUm, magnified.

— (Tab. CXCIX. B )
H a b . O u the ground; the collector’s name not mentioned. Barren.
A veiy remarkable plant, perfectly different from every other Sticta, and like nothing with which I am acquainted,
except Cttraria cucullata, Ach., to which in general appearance it is very similar. Some states of Spha-
rophoron australe, Laur., are not unlike it at first sight, insomuch that Dr. Taylor hastily passed it over as a form
of that species. The cyphellie are formed by the ruptures of the under surface, which leave roundish, white, excavated
spots.—P l a t e CXCIX. B. Fig. 1, portion of thallus, magnijied.

Hab. Tasmania, Gunn.
A single specimen, barren, in bad condition, but belonging apparently to this species, or at any rate allied to
it; perhaps it may be R. crenulala.

§ 1. I m b r ic a r ía , Frie s.
1. Parmelia p erla ta (Ach. Syn. p. 197; Bab. 1. c. p. 284).—P. perlata et P. reticulata, Tayl.!
H a b . 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. Parm elia sa x a tilis (Ach. Syn. Lich. p. 203; Bab. l.c . p. 285).—P . tenuirima, Tayl.! Lich.
Antarct. n. 71. P. sulcata, ejusd. n. 6 8 .
H a b . Among Moss, on Eagus-trunks, elev. 2000 feet; also on granite rocks, Launceston, Gunn.
Collected also by Hooker, etc. Fertile.
Some of Mr. Gunn’s specimens ai-e very fine, but are certainly only a form of P. saxatilis, Ach., i. e. of P . sulcata,
Tayl.! Other specimens are more hke the ordinaiy state of the plant, and ai'e named P . sulcata by Dr. Taylor-
himself.
3. Parmelia physod es (Ach. Syn. Lich. p. 2 1 8 ; Bab. I.e. p. 286).
Var. 0 . enteromorpha, Tuck. Syn. N. Amer. Lich. p. 28.—P . enteromorpha, Ach. etAuctt.
H a b . On trees, etc., fertile, Gunn, Archer.
Both the Acharian species occur, and that under various forms, some of which simulate the appearance of
4. Parmelia diatrypa (Ach. Syn. Lich. p. 219; Bab. l.c . p. 286).
H a b . On trunks of trees, Gunn (on Fagus). Cheshunt, Archer, etc. Fertile.
5. Parmelia tilia c e a ? (Ach. Syn. Lich. p. 199; Bab. l.c . p. 285).
H a b . On trees : Cheshunt, Archer.
Rather different from the Eur'opean form, but substantially agi'eeing (as it appears to me) with Tuckerm. Jjich.
Am. Exs. n. 70. Dr. Hooker appears to have found the same plant on Mount Wellington.
6 . Parmelia placorod ioid es (Nyl.! Eiium. p. 104).
H a b . On rails, “ very common,” Oldfield. But very few specimens have been collected.
The specimens are named by Dr. Nylander. A peqrlexing species, almost intennediate between P. tiliacea
and P . physodes. The habit is that of P. tiliacea, hut the structure of the thallus more resembles that of P. physodes.
We know not whether Dr. Nylander has described the species. P . placorodia, Ach., Tuckerinann! Licli. Am. Exs.
n. 71, is also extremely near to it.
7. Parmelia olivácea (Ach. Syn. Lich. p. 200; Bab. 1. c. p. 286).
H a b . Rocks : Richmond, Oldfield. Collected also by Hooker.
8 . Parmelia conspersa (Ach. Syn. Lich. p. 209; Bab. l.c. p. 286).—P . Tasmanica, Tayl.! Lich.
Ant. n. 70.
H a b . 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).
H a b . 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).
H a b . Trees, rotten wood, and stones, various collectors. Fertile.
Almost a cosmopolitair, as it would appear from Dr. Nylandcr’s euumer-ation and our own herbarium, but not
included in the ‘ Flora of New Zealand.’ This is the P . rutidota, Tayl. 1 Lich. Ant. n, 72, wliich differs in no respect
from the European form, except that the thallus is thicker thau usual (resulting from exposure ?) and nigropunctatc
