General Environment
This is a marine species.
Description
Plants typically localized in small clumps. Individuals stipitate, stipe ~1 mm wide and 1-2 mm tall and bearing a single blade, these blades only very rarely bearing marginal blades. Plants thus essentially foliose consisting of a single simple blade, 1.0-2.5 cm in diameter, isodiametric, oblong, or wider than tall with loosely undulate margins, typically prostrate to the substrate. Blades at times clearly developing peltately from the stipe, this especially true for the rarely developed marginal blades (although some may result from blade anastomoses). Blades 200-300 µm thick in longitudinal section near the margin, composed of a moderately filamentous medulla with occasional stellate medullary cells observed throughout the section. Inner cortex of 2-3 cell layers, outer cortex slightly dorsiventral with 1(-2) versus (1-)2 cell layers on the ventral and dorsal surfaces, respectively. Ventral cortical cells 3-6 µm wide, 5-8 µm tall; dorsal cortical cells 3-5 µm wide by 3-6 µm tall. Reproduction not observed. Best identified by comparison to the type COI-5P barcode sequence (GenBank: KF280921).
