OBSERVATIONS ON LIAGOROPHILA ENDOPHYTICA,A RARE SPECIES IN THE ACROCHAETIACEAE (RHODOPHYCEAE)1

Liagorophila, a monotypic genus in the Acrochaetiaceae (Nemalionales) from the zuestern Pacific, is redescribed, particularly with reference to its sexual reproductive structures. The fertilized carpogonium shows a longitudinal first division; the spermatangia may be borne directly on a normal vegetative cell. Monosporangia are not known. For these reasons, and although vegetatively resembling some species of Acrochaetium, the genus should be recognized as distinct from other genera of Acrochaetiaceae.
