OF FILAMENTOUS, FRUTICULOSE, AND FOLIACEOUS LICHENS. 157 
Specimen 3.—Falkland Islands, Dr Hooker, in Herb. Hooker, Kew. Besides 
marginal spermogones, apothecia are abundant, and are quite those of C. pywidata. 
Specimen 4.—Road to Wellington Falls, Van Dieman’s Land, Mossman, 1850 ; 
in Herb. Royal Botanic Garden, Edinburgh. No apothecia, but spermogoni- 
ferous scyphi. 
Specimen 5.—ScuZReER exs. 589 (sub @. longipes, ». denticulata); in woods. 
The name denticulata would appear to have been given in allusion to, or in con- 
sequence of, the spermogoniferous fringe of the scyphi, which is precisely like 
that so common in C. pyxidata. The spermatia are zth long. 
Specimen 6.—ScHZRER exs. 640 (sub @. ochrochlora); on the ground in the 
valley of the Mittenwald, Upper Bavaria. The spermogones are large barrels, 
which are seated in groups of two or three on the edge of the narrow scyphi 
which terminate the podetia. The sterigmata, with the spermatia attached, 
measure about ;,th to sath long; they become brown when old and sterile. 
Specimen 7.—Long Island, United States, May 1856, Dr A. O. Bropiz. The 
spermogones are small irregular barrels or cones, fringing the scyphi, precisely | 
as in C. pyaidata. 
SPECIES 3. C. cornuta, Fr., 
Which is said to occur in Europe, Asia, and America ; it appears to me to belong 
partly to C. pyaidata, and partly to C. gracilis. 
Specimen 1.—Craig-y-Barns, Dunkeld, April 1856, W. L. L. This seems 
referrible to C. pyxidata. The spermogones are few, but large and distinct, brown 
barrels, occurring on the margins of the scyphi. 
Sprciges 4. C. degenerans, Flk., 
Which occurs in Europe, Asia, and America; it does not appear to me to deserve 
to rank as a distinct species, but to belong to C. pyaidata, C. gracilis, and C. squa- 
mosa, if not to other species. 
Specimen 1.—ScuH.ZRER exs. 275 (sub L. euphorea, Flk.); on stones, Gastern. 
This is referrible to C. gracilis. The spermogones are large barrels, three or four 
of which are seated on the margins of each of the small narrow scyphi, which 
terminate the short slender podetia. No. 274 (sub £. aplotea, Flk.}, from the same 
locality in my copy, is not distinguishable from No. 275, either as to its thallus or 
spermogones. 
Specimen 2.—Kollong, Khasia, Himalayas; temperate region, at an elevation 
of 5000 feet; collected by Dr Hooker and Dr THomas Tuomson. The spermo- 
gones are abundant and large. Another specimen, also in the Hookerian Herba- 
rium, NYLANDER seems to refer to squamosa, but it is really intermediate between 
squamosa and furcata. It has abundance of large spermogones, on dark-brown 
dingy degenerate podetia.
