General Environment
This is a marine species.
Description
Blades pinkish-red, lacking stipe, round to ovate (0.5-3
mm at 21 ± 2°C) or linear-lanceolate (10-25 mm at 14 ±
2°C). Margins of mature blades moderately undulate giving
thalli a slightly ruffled appearance. Blades monostromatic,
19-21 µm thick. Cell divisions diffuse and marginal.
Marginal cells in one or two rows, quadrate (20-24
µm) to elongate, 20-24 µm wide and 40-48 µm long; central
vegetative cells becoming irregularly arranged,
polygonal (19-24 µm); basal cells irregularly arranged,
polygonal and becoming elongate, mostly larger than
central vegetative cells, chloroplasts single and stellate
with one pyrenoid. Archeosporangia along the upper
blade margin, regularly arranged, relatively quadrate
(19-22 µm). Liberated archeospores 10-14 µm in diameter,
exhibiting amoeboid and gliding motility.
Monoecious; spermatangia conspicuous, elongate, pale
streaks along the upper blade, intermixed with streaks of
presumed phyllosporangia; 32 spermatangia formed by
division [a/4, b/4, c/2], 4-6 µm in diameter, immotile
when discharged. Phyllosporangia dark pinkish-red,
larger than spermatangial cells, single or divided into
groups of 2-4; phyllospores 14-16 µm in diameter and
exhibiting amoeboid motion. Conchocelis pinkish-red
dense tuft of fine, branched, uniseriate filaments with the
ability to embed in mollusc shells. Cell divisions intercalary.
Cells short to elongate, 9-12 µm wide and 32-40
µm long, connected by primary pit connections; chloroplast
single, elongate, twisted and parietal with one or
more pyrenoids. Conchosporangia dark pinkish-red,
formed as uniseriate filaments and in clusters of 2-12
cells, isodiametric in surface view, short to elongate, 10-
27 µm wide and 7-27 µm long. Liberated conchospores
10-14 µm in diameter, exhibiting amoeboid motion.
