(a) only genera included on this site are listed

(b) type species from AlgaeBase or relevant publications

(c) if coloured red, indicates the location of the reference strain

(d) the number of sequences of the type species in parentheses

(e) with strains identified as type spp. of Funiculus, Trichocoleus and Coleofasciculus

(f) blue: axenic strain

The following strains are represented by isolates whose 16S rRNA sequences are of very poor

This artificially increases their apparent distance from other organisms, creating false genera.

These have been omitted from our 16S rRNA trees and should be considered invalid:
