Falklands, etc.) CRYPTOGAMIA ANTARCTICA. 143 
Primum maculas orbiculares exhibens, quee demum confluendo areolas tenues longe effusas omnes matricis 
insequalitates observantes efficiunt ; album, ut plurimum pellucidum, quandoque .opacum, tenue gelatinosum, sub- 
tiliter pruinosum atque exinde nitidulum, inodorum, insipidum ; exsiccatum sordide umbrinum. Margo tenuis, 
nequaquam fimbriatus, hic illic exsiccatione liber. Spore ellipticee, majores. 
Nearly allied to Corticiwm viscosum, but not in the least cracked when dry. I have found the same species, 
apparently, in Sherwood Forest, which I had referred to C. viscosum ; but the characters given by Fries, in his 
* Epicrisis,' indicate a distinct species.*

Haz. Hermite Island, Cape Horn; on a dead trunk of Deciduous Beech, almost covered with former 
winters’ snow, 1,200 feet above the sea, in an exposed place. 
The only specimen seen.

Haz. Port Famine; on Beech, C. Darwin, Esq. Hermite Island, Cape Horn; J. D. H. 
'The specimens collected in the latter locality are small and less tomentose than the more usual state of the 
species.

Haz. Hermite Island, Cape Horn; on moss near the sea, always solitary. 
The specimens differ from the ordinary form, which occurs in the southern as well as in the northern hemi- 
sphere, in their solitary habit, more conical peridia, which are of a semi-transparent dirty orange-yellow, and in the 
more irregular sporangia. In structure I find no difference.

Has. Falkland Islands; on a tuft of ۰ 
One specimen only was met with. 
It is not possible to speak very positively of a single old specimen and which had been evidently much exposed 
to the weather. It is, however, certainly neither Z. gemmatum, nor L. pyriforme, and appears to me to be a state 
of L. celatum. L. arenarium, Pers., will be found under the genus Bulgaria. 
9. LEPTOTHYRIUM, Kee. 
1. Leprornyrium decipiens, Berk.; suborbiculare, atrum, nitidum, sporis tenerrimis irregulari-subfusi- 
formibus quandoque curvatis. (Tas. CLXIIL. Fig. IIT.) 
* An authentic-specimen, however, received from Mons. Lindblad, since the above was printed, is not more cracked 
than the Antarctic plant. Corticium tremellinum must be considered, therefore, merely a highly developed form of 
C. viscosum,
