Plant investing the stems of small algae, of an orange colour when recent ;
when dry, colourless ; shining with a glassy lustre. Corpuscula nearly
linear, half a line in length, slightly widening upwards, rigid, pellucid,
placed side by side in a plane radiating or flabelliform manner, easily
separating laterally from each other, but, though divided into several
parcels, adhering by the base to the receptacle. Receptacle peUucid,
mostly hemispherical, but sometimes so elongated as to equal in length
the corpuscula it supports.
This beautiful plant I alluded to iu the preceding number
of this work. The most striking feature in it, is the receptacle,
which is simple, and liable to vary in form; but otherwise
bears the same relation to the slender corpuscula, as the
branched stipes does in Exilaria flahellata. The plant is conspicuous
for its shining, glistening appearance, resembling in
the strongest manner minute portions of spun glass. In this
character it is nearly allied to Exilaria crystallina (Diatoma
