Type Information
Type locality: Nakagusuku Bay (26º17'21.3"N;127º50'16.5"E), Awase, Okinawa, Japan; (Faye & al. 2008: 105) Holotype: M. Uchimura; 14 May 2006; SAP; 102817 (Faye & al. 2008: 105) Notes: Isotypes.
Description
Thallus upright, to 1-2.5 cm high, anchored
in sandy substratum by a basal tuft of rhizoids, olive- to
dark green in colour; axes terete, simple to 3(-4) times
dichotomously branched, 0.5-1 mm in diameter, hardly
tapering toward the apices, unconstricted; apices rounded. Thalli composed of longitudinally arranged
interwoven medullary siphons, 20-60 µm wide, giving rise
to a single layer of peripheral utricles; utricles polygonal in
surface view, with a rounded apex, approximately
isodiametric in transverse section, (70-) 128-147 (-187) µm
in diameter and (113-) 132-147 (-172) µm high,
adhering laterally to neighbouring utricles except at the
corners; utricle stipe not eccentric. Chloroplasts and
amyloplasts predominantly present in the siphons. Reproductive
structures unknown.
/Plants erect, light- to olive-green in colour, arising from a filamentous base and consisting of cylindrical, undivided or infrequently subdichotomous, unconstricted axes, 1.0-2.0 cm long, 0.5-1.0 mm wide. Medullary filaments or siphons 10-100 microns in diameter, irregularly constricted and deeply pigmented. Cortex composed of a confluent layer of globular to subspherical, cohering utricles, 50-200 microns in diameter; the utricles are sometimes colourless or containing markedly fewer pigments than medullary siphons. Reproduction unknown.
Habitat
Relatively deep habitats, -30 to -40 m, but Japanese specimens appear to grow in shallower parts of the coastline between -8 and -12 m (De Clerk et al. 2008)
