CONFERVA BANGIOIDES, Harv. 
Guy. Cuar. Filaments green, jointed, attached or floating, unbranched. 
Fruit, aggregated granules, or zoospores, contained in the articu- 
lations, having, at some period, a proper ciliary motion.—CoNFERVA 
(Plin.), from conferruminare, to consolidate; because some of the 
species were used by the ancients in cases of fractured bones. 
Conrerva Jangioides ; filaments attached, elongated, very slender, soft and 
lubricous, wavy ; articulations about twice as long as broad, containing, 
at maturity, a compact dark green mass; dissepiments broad, pellucid.

Descr. Filaments from three to six inches in length, capillary, densely tufted, or 
spreading in large patches, which are dark green and glossy to the eye. 
Each filament is of equal diameter throughout, but there is much difference 
between the relative diameters of filaments from the same tuft. The arti- 
culations are about twice as long as broad, slightly contracted at the dis- 
sepiments, and filled with a dense herbaceous green endochrome, leaving a 
pellucid border all round. In an advanced stage of growth the endochrome 
contracts and condenses into a dark-coloured, oblong spore, which remains 
in the centre of the articulation, until, on the breaking up of a plant, it is 
liberated. Substance lubricous, closely adhering to paper in drying. 
The species here figured is, in many respects, similar to 
C. Youngana, but is a larger species. From most others it may be 
known by its very lubricous and glossy tufts and soft feel. 
Except in colour there is much outward resemblance to Bangia 
Juscopurpurea, though under the microscope no two plants need 
be more unlike. When the plant first makes its appearance the 
colouring substance nearly fills the cell, and is of a pale colour, 
but gradually it condenses into a small, subcylindrical and dark- 
coloured spore in the centre.
