Falklands, etc.] FLORA ANTARCTICA. 449 



Primura maculas orbieulares exhibens, qua; denium couflueudo areolas tenues longe effusas oinues matricis 

 inaequalitates observantes efficiunt ; album, ut plurimum pelluciduvn, quaudoque opacum, temie "elatinosum sub- 

 tiliter pruinosum atque exinde nitidulum, inodorum, insipidum ; exsiccatuin sordide umbrinum. Mareo tenuis 

 nequaquam fimbriatus, hie illic exsiccatione liber. Spores ellipticae, majores. 



Nearly allied to Corticimn 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.* 



5. TEEMELLA, L. 



1. Tremeela mesenterica, Eetz, in Vetensh Ac. Handl. 1769, p. 249. Engl. Bot. t. 709. 



Hab. 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. 



6. EXEDIA, Fries. 



1 . Exldia Auricula Judez, Fries, Ep. p. 590. 



Hab. Port Famine ; on Beech, C. Darwin, Esq. Hermite Island, Cape Horn ; /. D. If. 



The specimens collected in the latter locality are small and less tomentose than the more usual state of the 

 species.

 p. 238. Grev. Scot. Crypt. Fl. t. 34. 



Hab. 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. 



8. LYCOPEEDON, Tourn. 



1. Lycoperdon calatum, Bull. Champ, vol. i. p. 156. t. 430. 



Hab. Falkland Islands ; on a tuft of Bolax. 



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 L. (jemmatum, nor L. pyriforme, and appears to me to be a state 

 of L. calatum. L. arenarinm, Pers., will be found under the genus Bulgaria. 



9. LEPTOTHYEIUM, Kze. 



1. Leptothyrium decipiens, Berk.; suborbiculare, atrum, nitidum, sporis tenerrimis irregulari-subfusi- 

 formibus quaudoque curvatis. (Tab. CLXIII. Fig. III.) 



* An authentic specimen, however, received from Mons. Lindblad, since the above was printed, is not more cracked 

 than the Antarctic plant. Corticium tremellimim must be considered, therefore, merely a highly developed form of 

 C. viscosum.
