las mine This being quite unlike any of the hitherto described Hepatice, we attached the generic name of Riccia from a cer- 
tain resemblance in the form of its frond to several species of that genus, but the plant is more probably allied to some 
frondose Jungermannia,—J. epiphylla for instance. The concave frond with entire connivent lobes, partakes of the 
P the roots habit of that of Collema granulatum, Ach., but our plant is certainly a Hepatica.

; The number of Fungi collected during the Expedition is very small, in proportion to that of other cryptogamic 
very hg plants, with the exception of those found in New Zealand and Van Diemen’s Land. In the more southern locali- 
l ties, Fungi may naturally be expected to cease, sooner than Alge, Lichens, and Mosses; and accordingly, from 
such localities, the amount of species is trifling indeed. Even where the degree of cold is not sufficient to prevent 
the growth of Fungi, their fructification is materially affected; and thus, in the higher forms, the hymenium will 
frequently be found barren ; while, in some hypogæous species, transformations of the sporophores themselves take 
place, causing the fructifying mass to assume a very anomalous appearance, Some species indeed, as Pilobolus 
erystallinus and Hydrophora stercorea, seem to flourish most in the frosty nights of autumn, and the species of the 
regions d s genus Chetonypha and Lanosa nivalis thrive either beneath or upon the surface of the snow; but I know of no other 
xeeligy exceptions to the more general habit of these species, and in these cases, the temperature either does not descend 
ermine ih below the freezing point, or, as in the case of the Chetonypha, vegetation takes place only when the surface of the 
ihary snow is just melting under the influence of the sun. 
Amongst the more northern islands visited by the Expedition it is probable that some interesting forms, had 
time allowed, would have rewarded further research; though, indeed, constant attention was directed, even to the 
obscurest forms of vegetation, wherever circumstances would permit. As it is, there is a considerable number of 
new species to describe, and some of them possess much interest, especially a new Cyttaria from Cape Horn, the 
i specimens of which are so numerous as to afford an excellent opportunity of examining the structure of this curious 
genus; which, like Podisoma and Gymnosporangium, which infest certain species of Juniper, developes itself on the 
living branchlets of the deciduous-leaved Beech. Some of the species, like those of other Cryptogams, are identical 
| with plants of the Northern Hemisphere; and this is especially observable in New Zealand, where the identity is 
not confined to those families in which it is more usual.
