摘要

Abstract

The genus

Selenastrum

comprises common coccoid green algae found in diverse habitats worldwide. This genus has a complex taxonomic history

but recent applications of molecular phylogenetic methods have removed some members with similar morphologies from

Selenastrum

and established new genera. However

due to the lack of available molecular sequences and isolates

the species diversity of the genus has not been fully explored. We conducted a detailed examination of the taxonomy of genus

Selenastrum

based on 11 new strains collected from China. The multi-disciplinary study utilized morphology

ultrastructure

and phylogeny based on multiple molecular markers

and ITS-2 s

econdary structure. All the included strains of genus

Selenastrum

were clustered into two distinct clades. The members of one clade were similar morphologically to the type species

Selenastrum

bibraianum

whereas the strains of the other clade had distinctly different colony structures. Based on the latter clade’s larger colony cell numbers and independent phylogenetic position

we proposed that it as a new species of the genus

Selenastrum

namely

Selenastrum

densum

sp. nov. Additional taxa sampling and molecular data will help to discover additional new species and clarify the validity of morphological taxonomic characteristics within the genus

Selenastrum
