Cladophoropsis Børgesen

Key to the species from Rodrigues

1 Filaments dark green, rigid, often sympodially branched, aseptate rhizoids sprouting from the base of most cells; apical cells 180–260 mm in diameter... C. herpestica

– Filaments medium to light green, monopodially branched, no descending rhizoids sprouting from the base of the cells, short hapteroidal rhizoids present throughout the thallus; apical cells 60–120 mm in diameter......... C. sundanensis
