AÜ tlie European forms occur in Tasmania, as weU as a modification marked Usnea scabrida, Tajl., iu Jas.
Drurmn. Swan Riv. Crypt., by Dr, Taylor. It is only a very fibrUlated form of U. Jlorida, Acb., not mucb different
from U. strigosa. Mr. Lawrence has collected barren, sorediated forms, witb a black base and blackish extremities,
w'ithout fibrilla, which are uot veiy unlike U. melaxantka, at an altitude of 3,500 feet, on the highest parts of the
western range of mountains.

Mr. Gunn’s specimens are above two feet long,
3. U sn e a melaxantha (Acb. Syn. Lich. p. 3 0 3 ; Bab. I.e. p. 269).
H a b . Arthur’s Lakes, Gunn. Ou rocks, uear the springs. Mount Wellington, Hooker, Mossman.
Bai-rcn and sorediated, and very sparingly collected.
Gen. I I . EVERNIA, Ach.
1. E v ern ia fu rfura cea ? (Mann; Fries, Lich. Eur. p. 26).
H a b . Cheshunt, Archer, fertile.
An aged, unsatisfactory specimen, black beneath, but above more resembling E. prunasiri, Ach.; upper surface
much coiTugated. Possibly something different ft'om E. furfuracea or E. prunasiri. I have not seen a description
of Evemia inúndala, Nyl., from New Hollaud.
Gen. I I I . RAMALINA, AcL
1. Ramalina ca lica r is (Fries, Lich. Eur. p. 30).—Approaching \&t. geniculata, Bab. I.e.
H a b . Esk, Launceston, completely investing shrubs of Hgmcnantkera angustifolia, Gunn.
The specimens agree substautiaUy with E. fastigiata, Ach., but still more ivith the fom called R. geniculata
by Dr. Taylor.
0 . ovalis, Bab.; thallo ovali piano tenuiore, apotheciis minutis, confertis.—R. ovalis, T a yl.! MSS.
H a b . Tasmania, Gunn.
Apothecia minute, scattered over the surface of the somewhat membrauaceous, oval froud, which is 1-2
inches long. One of the many modifications of the form called R. fraxinea, Ach.—Laurer’s var, membranacea, Bab.
1. c., has the fronds narrower and longer, and the apothecia marginal; but it is perhaps hai'dly worth while to dwell
on minute differences in this most vaiiable genus.
2. Ramalina p u silla (Fries, Lich. Eur. p. 2 9 ; Nyl. Enum. p. 99).
H a b . Macquarrie Plains, on decayed wood, Oldfield. Recherche B a y , dead twigs, Lake St. Clair, St.
Patrick’s River, Gunn. Cheshunt, on live bark and dead twigs. Archer.
1 have already, in the ‘ Flora of New Zealand,’ expressed an opinion that this is not distinct from the foregoing.
Gen. IV. PELTIGERA, Iloffm.., Fries.
1. P e ltig e r a polyd a cty la (Fries, Lich. Eur. p. 4 6 ; Bab. 1. c. 271).
H a b . Cheshunt, Archer. Collected also in Tasmauia b y Lawrence, Gunn, Stuart, and Ilooker.
Various specimens differ amongst each other in the consistency of the thallus; some of Mr. Archer’s specimens
are coriaceous, others quite membranaceous.
2. P e ltig e r a ho rizon ta lis (Fries, Lich. Eur. p. 47).
H a b . Cheshunt, Archer.
■Well-marked fertile specimens. Seemingly rare in the southern hemisphere, but occurring in the Himalaya
Mountains, as well as in Europe and North America.

Hab. Ou bark: Cheshunt, Archer. Mount Wellington, Hooker.
Nylander’s enumeration omits all notice of N. australe.

Hab. Rotten wood: Johnny’s Creek, Oldfield. Cheshunt, on dead wood. Archer. Mount Wellington,
Hooker and Gunn.
The specimens (of a deep-brown colour) agree with one from Staten Land marked Nephroma cellulosum in
Menzies’ handwriting. N. plumbeum, Mont.! Fl. Fern. n. 7, seems to be the same plant, but somewhat paler, whicli
has been found also by Gunn. Found in Chili, according to Nylander (who keeps N. plumbeum and N. cellulosum
distinct), as well as in Juan Fernandez.—P l a t e CXCIX. »7. Fig. 1, apothecium; 2, under surface of ditto;

Hab. Among Mosses, on wood, etc. Everywhere, all collectors.
Fertile specimens are bright, and often much pitted, and, being destitute of the yellow soredia which are
usually present on the barren fronds, wear a somewhat different appearance to the European state of the plant.
3. S tic ta C o len so i (Bab. I.e. t. 123).
Hab. Very abundant in forests, on Fagus, Gunn, Hooker.
Less divided than the New Zealand form.

Hab. On rocks ; near the caves. Back River, Oldfield. Running over sticks among Mosses. Hooker.
Some specimens are less distinctly flabelliform than the ordiuai'y state of the plants; others, collected by Mr.
Oldfield, resemble the common type, but are much smaller.
