Abstract

Two new species of the red algal genus Myriogramme, M. melanesiensis and M. heterostroma, are described from subtidal habitats in the Solomon Islands and Vanuatu, South Pacific. Myriogramme melanesiensis is characterized by a tristromatic thallus with layers composed of subrectangular cells of approximately equal height, smooth margins lacking any spines or proliferations, and multiple ovoid to elongate two-layered, submarginal tetrasporangial sori. Myriogramme heterostroma is distinguished by its tri- to pentastromatic thallus, with a single large layer of clear medullary cells and smaller pigmented cortical cells, and tetrasporangia occurring in single, large, median sori.
