Abstract

Achlya catenulata sp. nov. was collected from water samples in a mangrove swamp of the ``Parque Estadual da Ilha do Cardoso{''}, Sao Paulo State, Brazil. This new species is characterized by the presence of achlyoid type of zoospore discharge from both primary and secondary sporangia, catenulate smooth-walled oogonia in chains of up to 11 oogonia, diclinous antheridial branches and eccentric oospores, which generally failed to mature. Maximum likelihood phylogenetic analyses based on the ITS and LSU regions (rDNA) placed this species within the Achlya sensu stricto clade. (AU)
