OF FILAMENTOUS, FRUTICULOSE, AND FOLIACEOUS LICHENS. 165 
Species 16. C. uncialis, Hoffm., 
Which occurs in Europe, America, and Asia. This and the species to follow 
are characterized by the absence of scyphi; in them the spermogones are terminal 
and more prominent than in those which have preceded. 
Specimen 1.—Moors about the Stro Rock, Isle of Skye, Aug. 1856, W. L. L. 
The spermogones are generally in groups of two or three, constituting or crowning 
the terminal horns of the podetia; their brown colour, in contrast with the straw- 
yellow of the podetia, renders them very distinct. They vary in length, being 
elongated and subfusiform or subspherical. The ostioles are large and patent in 
the older ones. The spermatia are chiefly straight—all the attached ones are; 
some are slightly curved ; their length is about ath. 
Specimen 2.—Hills east of Glen Callater, Braemar, Aug. 1856, W. L. L. The 
spermogones are distinctly-bulging barrel-shaped organs, with a perceptible 
ostiole. Their spermatia, as in No. 1, are straight or curved—the former while 
attached; their length is about goth. 
Specimen 3.—Ben Lawers, Aug. 1855, Dr Giitcurist of Dumfries. The barrel- 
shaped spermogones bulge most superiorly ; their base or pedicel is narrow. But 
there is always a distinct line of separation between the spermogone and podetium, 
both in respect to colour and thickness. 
Specimen 4—Rorrie Moor, near Forfar, A. Croatu of Montrose; in Herb. 
Hooker, Kew. Has the same spermogones as in No. 3. 
Specimen 5.—ScH@RER exs. 82 (sub C. stellata a. uncialis); on ground in 
the Alps and valleys of the Jura. Exs. 513 (sub C. stellata 8. ceranoides); on the 
ground on moors; has its spermogones on the horns or tips of large handsome 
podetia. Lake-coloured mucilage abounds in their interior, and this is note- 
worthy, seeing that the spermogones themselves are brown. ‘The spermatia are 
crescent-shaped, and about aoth long; the length of the sterigmata is about sth. 
Exs. 514 (0. adusta) has the spermogones just described. 
SPECIES 17. OC. turgida, Hoffm., 
A native, according to NyLANpER, of Europe, Asia, and America. I look upon it 
simply as a form, and a very ill-marked form frequently, of the preceding species, 
the podetia being usually shorter, thicker, darker, and considerably deformed. 
NYLANDER places C. turgzda, in his classification,* between furcata and rangiferina- 
Specimen 1.—Summit of the Bassies, Clova, 1843, GARDINER; in Herb. Hooker, 
Kew (sub nom. C. wncialis B. turgida). Possesses spermogones only, which are 
precisely those of C. uncialis.
