Reassessment of the classification of Bryopsidales (Chlorophyta) based on chloroplast phylogenomic analyses
The Bryopsidales is a morphologically diverse group of mainly marine green macroalgae characterized by a siphonous structure. The order is composed of three suborders – Ostreobineae, Bryopsidineae, and Halimedineae. While previous studies improved the higher-level classification of the order, the...

The Bryopsidales is a morphologically diverse group of mainly marine green macroalgae characterized by a siphonous structure.

The phylogenies presented here provided good support for the major lineages (suborders and most families) in Bryopsidales. In Bryopsidineae, Pseudobryopsis hainanensis was inferred as a distinct lineage from the three established families allowing us to establish the family Pseudobryopsidaceae.
