(c) if coloured red, indicates the location of the reference strain
(d) the number of sequences of the type species in parentheses
(e) with 2 strains mis-identified as type spp. of  Trichocoleus and Coleofasciculus
(f) blue: axenic strain
The following strains, described by Panou and Gkelis 2021 (Mol Phylogenet Evol 166, 107322),
are represented by isolates whose 16S rRNA sequences are of very poor quality (containing
many mismatches in the paired stems of many helices).
This artificially increases their apparent distance from other organisms, creating false “genera”.
We feel that these “genera” should be considered invalid.
