Origin of Species Name
Adjective (Latin), beautiful and little (Stearn 1973).

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.
