346 FLORA OF TASMANIA. [.Zichenes, by Babington & Mitten. 
Has. Johnny's Creek, Back River Gully, etc., Oldfield. Cheshunt, on wood, Archer. 
Specimens not fully grown, but evidently belonging to this species. 
7. Sticta Richardi (Mont. ! Fl. Fern. n. 79; Bab. Lei, 
Has. Among Mosses, Gunn. 
Very near the following. 
8. Sticta foveolata (Delise, Stict. p. 101. t. 8. f. 36; Bab. 1. c.). —(Tab. CXCVIII.) 
Haz. 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.—PLateE OXCVIIL Fig. 1, portion 
of frond and apothecia; 2, back of ditto; 3, portion of apothecium; 4, sporidia :—all magnified. 
9. Sticta Freycinetii (Delise; Bab. 1. c.). : 
Has. On wood, among Mosses, etc.; also running over live Ferns, Archer. Everywhere, all collectors. 
The specimens mostly belong to my var. 8 Delisea. Mr. Gunn finds beautiful specimens in forests of Fagus, 
at an elevation of 2000 feet. 
10. Sticta granulata (Bab. 1. c.). —(Tañ. CXCVIL.) 
Has. Cheshunt, fertile, Arche, Collected also by Hooker and Gunn, but their specimens are barren. 
This plant occurs also in Java, according to my learned friends Drs. Montagne and Van der Bosch.—PLATE 
CXCVIL Fig. 1, specimen, with apothecia, nat. size; 2, the same magnified; 3, sporidia; 4, back of thallus, 
showing cyphellee, magnified. 
11. Sticta fuliginosa (Ach. Meth. Lich. p. 280; Bab. Lei 
Haz, Cheshunt, on wood, barren, Archer. 
Apparently rare in the southern hemisphere. 
12. Sticta cetrarioides (Bab.); thallo submembranaceo substellato dichotome ramoso canaliculato 
sublacunoso, ramis ascendentibus dichotomis marginibus rotundatis erosis, supra glaucescente ochroleuco 
glaberrimo, subtus fusco subspongioso fibrillis atris longioribus, cyphellis excavatis albidis, apotheciis . . . 
—(Tas. CXCIX. B.) 
Has. On the ground; the collector's name not mentioned. Barren. 
A very remarkable plant, perfectly different from every other Sfic/a, and like nothing with which I am ac- 
quainted, except Cetraria cucullata, Ach., to which in general appearance it is very similar. Some states of Sphe- 
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 cyphellee are formed by the ruptures of the under surface, which leave roundish, white, exca- 
vated spots.—PLaTEÉ CXCIX. B. Fig. 1, portion of thallus, magnified. 
Gen. VII. RICASOLIA, De Not. 
l. Ricasolia herbacea? (De N.; Nyl. Enum. p. 103).—Sticta vel Parmelia herbacea, Auctt. ; 
Bab. l.c. p. 284. 
Has. 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. crenulata. 
= Gen. VIII. PARMELIA. 
$ 1. IMBRICARIA, Fries. 
l. Parmelia perlata (Ach. Syn. p. 197; Bab. l.c. p. 284).—P. perlata et P. reticulata, 7azy/./
