General Environment
This is a marine species.
Description
Thallus small, 1–2 cm high, growing as a dense
tuft, erect branches rising from compressed creeping
axes, attached to the substratum by peg-like holdfasts.
Erect axes compressed, 316–389 µm broad, 100–
166 µm thick; more densely branched on the middle
to upper parts (or rarely on branchlets) for one half
their lengths, with branches 3–5 (-9) times palmate,
apex obtuse and often broken, slightly constricted
at base; rarely proliferous from surface; purple red,
cartilaginous.
Transverse section creeping stem 132–145 µm
broad, 165–224 µm thick, consisting of a medulla
of irregularly angular parenchymatous cells, 11–20
?m × 8–13 µm, one layer of smaller cortical cells,
7–9 × 4–7 µm; transverse section erect axes
consist of a medulla of irregularly angular parenchymatous
cells, 10–17 × 7–13 µm, with one
layer of smaller cortical cells, 7–10 × 4–6 µm,
rare rhizoidal filaments found within two edges of
compressed medullary tissue.
Cystocarps unilateral, prominently protruding, triangular,
290 µm high, 422 µm broad, rostrate, unconstricted
at base; gonimoblast consisting of few small
cells, chains of carposporangia radiating from a core
of gonimoblast filaments surrounding the central axis,
carposporangia obovate, 17–26 × 8–10 µm, pericarp
53–59 µm thick, consisting of 5-8 layers of cells,
some inner cells elongated, extending to the placenta.
Tetrasporangia and spermatangia unknown.
