Belfast Lough, the habitat extending seemingly for miles. Baltic
specimens, as described by Agardh, are only a few inches in
length; and such arc some that I owe to the kindness of Dr.
Areschoug, of Gottenburg. Our Irish plants, on the contrary,
are comparatively giants; the tufts being often two or three feet
in diameter. I have been forced to select a small one for illustration,
but the character of larger plants is very similar. In all
respects, except luxuriance, the Irish and Baltic plants are
identical.
The branching is sufficiently unlike that of C. flageUiformis,
resembling much more closely that of Stitophora rhizodes, to
which outwardly our plant bears a very great resemblance. But
besides a difference in habit, it is well distinguished from C.
Jtagetliformis by the shape of the filaments of the periphery which
in that species are club-shaped, while in this they are slender,
but terminated by a large globular cellule. In this respect there
is a resemblance to a Mcsogtoia, but the structure of the axis is
exactly that of Chordaria.
