Falklands, ete.| CRYPTOGAMIA ANTARCTICA. 145 
ˆ Maculee rubellee; peridia plus minus elongata, urceolata, sursum leviter constricta, vel omnino cylindracea, 
fragilia, totam superficiem inferiorem investientia, plus minus in petiolos descendentia. Spore pallide (saltem 
in exemplaribus exsiccatis) irregulariter subglobosz, angulate. Rarissime pauca peridia epiphylla sunt. 
Resembling much in external appearance Æe. sambucinum, Schwein. It is at once distinguished from Heidium 
Berberidis by its very different habit. : 
Prate CLXIIT. Fig. 11.—1, leaves of Berberis and Heidium Magellanicum, of the natural size; 2, portion of 
leaf and fungus; 3, spores :—highly magnified. 
13. UREDO, Pers. 
1. Unzpo candida, Pers., Syn. p. ۰ 
Has. Falkland Islands; on Arabis Macloviana, Capt. Sulivan. 
The mycelium is very visible in these specimens. There is no difference in the spores. 
14. MORCHELLA, Dill. 
1. MoRCHELLA semilibera, Dec., Fl. Fr. vol. ii. p. 212. 
Has, Falkland Islands; on the ground. 
I have seen a single imperfect specimen only, which is scarcely more than sufficient to determine the genus. 
I believe it, however, to be the species of De Candolle, above cited. 
15. PEZIZA, Dill. 
1. Prziza Kerguelensis, Berk.; media, cupula plana adnata coccinea extus setis brevioribus obsita. 
(Tas. CLXIV. Fig. IIT.) 
Has. Hermite Island, Cape Horn; on dead branches amongst the snow, alt. 1,000 feet. Christmas 
Harbour, Kerguelen’s Land; May and June; on bare boggy earth near the sea, growing amongst Conferve. 
Cupula 4 
t unc. lata, plana, adnata, margine tantum ut plurimum libero, coccinea, externe setis brevioribus 
subflaecidis plus minus contextis primum pallidis deinde saturate rubris vestita, dissepimentis demum absorptis. 
Asci lineares, obtusi; sporidia late elliptica, glabra, nucleo unico globoso ; paraphyses apice clavulatee. 
Allied to P. scutellata and P. umbrosa, but larger than either. The bristles are short and somewhat flaccid, 
in which it differs strikingly from the former species, as also in its broader sporidia. From the latter it 
differs principally in its larger size and less conspicuous hairs. Tam not able, in the absence of authentic specimens, 
to compare the sporidia; but if that species be the same with P. trechispora, Berk., and Broome, which is not 
impossible, the difference is considerable. 
Prate CLXIV. Fig. III.—1, Kerguelen's Land, and 2, Cape Horn specimens; of the natural size; 3, sete: 
—magnified ; 4, asci, sporidia and paraphyses ; 5, sporidia :—very highly magnified. 
2. Peziza stercorea, Pers. Obs. vol. ii. p. 89. (Tas. CLXIII. Fig. IV.) 
Haz. Port Louis, Falkland Islands; on cow-dung. 
Not distinguishable from European specimens. T cannot detect Ascobolus furfuraceus, which is so generally its 
companion in Europe. 
Prare CLXIIT. Fig. IV.—1, bristles from cup; 2, asci and paraphyses, in the broken ascus the inner mem- 
brane is visible, projecting below ; 3, sporidia :—all highly magnified.
