Description

Genus Celeceras Kützing

TYPE SPECIES. — Celeceras monile (Hooker & Harvey) Kützing.

REMARK

A valid name resurrected here because the type species Celeceras monile (Hooker & Harvey) Kützing, a synomym of Ceramium puberulum (Womersley 1978), is nested within this clade. These samples have 4-5 cortical initials with 2-3 descending filaments, tetrasporangia from periaxial cells, and are found only in the South Pacific.

KEY CHARACTERS

Terete to compressed thalli. Node formed by 6-10 periaxial cells cutting off 4-5 cortical initial cells with 2-3 descending filaments. Tetrasporangia formed by periaxial cells, 2-4 per node, partially covered by cortical cells to immersed in thalli, whorled, sometimes in stichidia-like.

Rbc L alignment positions 522-546 5’TTCAATCGCTGCAACAGGCGAAGTG3’ generated in this study.
