title: PULCHRASPHAERA, A NEW CHLOROCOCCALEAN GENUS(1).
abstract: Pulchrasphaera macronucleata gen. et sp. nov. was isolated from a sand dune on Dauphin Island, Alabama. The distinguishing attributes of the genus include a lobed and perforate parietal chloroplast, lack of pyrenoids, and Protosiphon-type zoospores. The specific epithet calls attention to the unusually large nucleus, a character useful in distinguishing P. macronucleata from other spherical, zoospore producing members of the Chlorococcales.
