# List of Ulvophyceae genera

The Ulvophyceae or ulvophytes are a class of green algae, distinguished mainly on the basis of ultrastructural morphology, life cycle and molecular phylogenetic data. The ulvophytes are diverse in their morphology and their habitat. Most are seaweeds, although a select few live in fresh water.
This list of Ulvophyceae genera is sub-divided by order and family. Some genera have uncertain taxonomic placement and are listed as incertae sedis. The list is based on the data available in AlgaeBase, the Integrated Taxonomic Information System (ITIS), the National Center for Biotechnology Information taxonomic database (NCBI), and other taxonomic databases.
