5 magni- A very singular substance, which must strike the traveller through the woods especially of New Zealand or of 
Lord Auckland’s group, in both which localities it is very abundant, resembling charcoal, and sometimes so widely 
diffused that the branches look as if burnt. The colonists of the former islands call it “the black moss.” Distin- 
guished from 4. pannosa and A. Robinsonii by its long fasciculate threads, giving it exactly the habit of Scorias 
spongiosa. The finest specimens have a rigid bristly appearance, quite different from that of any other species of 
ma, as the genus. This has been also gathered in Valparaiso by Mr. Bridges, and at the Swan River by Mr. Drummond. 
I have not been able to trace the developement of the peridia in the Auckland Island specimens, but it would ap- 
pear that, as in M. Robinsonii, M. and B., they arise either from a swollen articulation or from a process given off by an 
articulation, in either case they are dependent on a simple metamorphosis of the latter.

This production is enumerated here because it has hitherto appeared in the works of Mycologists, but I am 
decidedly of Léveille’s opinion that it should be expunged.

util | Oss. The genera Marginaria, A. Rich., Carpophyllum, Grev., Scytothalia, Grev., and Seirococeus, Grev., are all 
! very closely related to each other, and to Sargassum. From the latter they differ more by possessing a frondose, 
riy | imperfectly leafy mode of growth, than by any very decided structural character; and habit alone will scarcely se- 
parate some of them from the decurrent species of that genus, S. decurrens, Peronii, Boryi, &c. These last have
