Summary J aoa prasina , a freshwater green alga endemic to C hina, was collected from a stream in H ubei province, C hina. Unialgal cultivation, morphological observation, and phylogenetic analyses of small subunit ribosomal DNA and RuBisCO large subunit sequences were performed. When cultured on agar medium, the alga was irregularly filamentous, similar to marine species of A crochaete . Aplanospores were observed on solid medium. A vesicular‐like thallus without rhizoids developed in liquid medium, similar to specimen development in natural habitats. Molecular phylogenetic analyses revealed that J aoa was closely related to the marine genera A crochaete P ringsheim and U lvella C rouan & C rouan. The results suggested the genus J aoa is a member of the family U lvellaceae ( U lvophyceae), which contains mostly marine algae. The family name J aoaceae should be abandoned. We speculate that J aoa may have evolved from a marine U lvellaceae ancestor.
