On Lichens and old trees, not uncommon.

(Helmisporium?)

On rocks and trees, in alpine districts.— " Stratum of indefinite extent,
thin, velvetty-hlack. Filaments scarcely more than a line (or two) in
length, interwoven, slightly branched, extremely fragile. Articulations
about as broad as long, rather translucent. I have found specimens of
this plant, bearing pod-shaped branches or appendages, thicker than the
main filament, with the articulations twice as broad as long, and readily
separating into single joints." Carm. MSS.— These pod-shaped appendages
are surely of the same nature as what are called " sporidia" in the
genus Helmisporium of Link; to which genus, the black species of
Chroolepus ought, perhaps, to be removed.
6. C. melcenus, Carm. (long-jointed black Chroolepus) ; filaments
slightly branched erect forming a jet-black stratum, articulations
oval twice as long as broad, joints < outi-acted.— S////collcsin
