Liagora ceranoides   J. V. Lamouroux,  1816 (Algae)
Organism information awaits expert curation
Class: Florideophyceae

Color: Pale grey

Thallus form and type: Bushy and mucilaginous

Substratum: Intertidal rocks and dead corals

Occurrence: Mid littoral zone, tide pools and streams

Season: November-April

Abundance: Moderate

Thalli 3-4 cm high, upper cells 8-12 µm diameter and 1-2 diameters long, moderately calcified, appearing farinaceous-pulverulent, regularly and repeatedly dichotomously branched in a corymbose manner. Branches cylindrical 1 mm diameter at the basal part, tapering towards the apex. Calcification peripheral among the assimilatory filaments. Cortical assimilatory filaments about 250 µm long, 5-6 times dichotomously branched in a corymbose manner, upper cells subglobose or ovoid and lower cells subcylindrical, about as broad but much longer, generally about 4-6 diameter long. Hyaline hairs found on the terminal assimilatory cells. Medullary filaments about 24-60 µm diameter, usually 10-12 times but sometimes as much as 20 diameters long. Rhizoidal filaments issuing form the basal cells of the assimilatory filaments, generally 6-8 µm diameter.

Plants dioecious. Spermatangia subglobose to oblong, 2-3 µm diameter borne single or in two to fours at the ends of cylindrical filaments growing out corymbosely from the terminal ovoid assimilatory cells. Carpogonial branches generally 4 celled, 12-14 µm diameter, slightly curved and situated laterally on the middle part of the subcylindrical assimilatory cell, generally just above the second dichotomy from the base. Mature cystocarps involucrate with well developed long, ascending filaments.
