may become maculiform. The spermogones may be papilleeform about the ends 
of the lobes, and punctiform, fiat, or depressed more centrally. Sometimes they 
are so abundant as to give the thallus a black or brown-punctate character. 
Sprcius 8. 8S. Freycinetii, Del., 
Which occurs in equatorial America, Australia, and the Antarctic Regions. 
Specimen 1.—Auckland Islands, Dr Hooker, in Herb. Hooker, Kew. The 
spermogones resemble those of S. orygmwa; they are mostly punctiform and 
- depressed, though sometimes papilleeform. Hooxer apparently describes them 
as abortive apothecia in his ‘“ Flora Antarctica,” (Part 25, p. 528, Plate 196, 
fig. 4.) 
Specimen 2.— Var. fulvocinerea, Mont. (Syn. Sticta fulvocinerea, Mont.) 
Straits of Magellan, Captain Continson. The spermogones are scattered imme- 
diately on or near the margins of the thallus; they are generally papilleeform 
and crowded, with a deep-brown or black ostiole or apex. Sometimes they are 
punctiform and flat, seldom depressed. The thallus is of a beautiful lemon- 
yellow colour; hence the spermogones are easily seen. 
Specimen 3.— Var. Gaudichaudii, Deu. (Syn. Sticta Gaudichaudii, DEL.) 
Australia, BrpwitL; in Herb. Hooker, Kew, as is also No. 2. The spermogones 
occur on the margins of the lobes, and are papilleeform and small, with a pale- 
brown apex. — 
Sprcries 9. S. laciniata, Ach. 
Specimen 1.—Xalapa, Mexico, Harris; in Herb. Hooker, Kew. This isa large, 
handsome species. The spermogones are subpapilleeform, sometimes flattened, 
scattered abundantly about the ends of the lobes. 
Species 10. S. faveolata, Del., 
A native of equatorial America and Australia. 
Specimen 1.—Chili, Lops; in Herb. Hooker, Kew. The spermogones are 
minute, depressed brown points, scattered on the rugze, precisely as in S. pulmo- 
Nace. . 
Specimen 2.—Var. Richardi, Mont. (sub Sticta); which occurs in Chili, Aus- 
tralia, the Auckland Islands, and New Zealand. A specimen from New Zealand, 
1853, in Herb. Hooker, Kew, greatly resembles S. pulmonacea in its linear laciniz, 
and its punctiform spermogones distributed on the thalline rugz. 
SPECIES 11. S. obvoluta, Ach. 
Specimen 1.—On the trunks and branches of trees in hill woods, Juan Fernan- 
dez, 1830; in Herb. Hooker, Kew; a very beautiful species, with marginal large ~ 
handsome apothecia. The spermogones are the largest I have found in either the
