摘要

Abstract

The genus

Neglectella

Vodenicarov

Benderliev has a morphology similar to the well-known genus

Oocystis

except for the numerous chloroplasts stacked in the surface layer of the cell.

Neglectella

subsequently experienced complex taxonomy changes with members being transferred in and out

and five species are now accepted. In this study

a new alga with morphology corresponding to this genus was collected in China and successfully cultured in laboratory. Morphological observations in light microscopy and transmission electronic microscopy (TEM) and phylogenetic analyses revealed that it is a new species

described here as

Neglectella glomerata

sp. nov. It differed from other

Neglectella

species due to a morphological difference in its unique mucilaginous colony with a large number of cells

multiple pyrenoids in each chloroplast

smaller cell size

and more elongated cell shape. Phylogenetic analyses placed this alga in the subfamily Eremosphaeroideae of the family Oocystaceae and showed its close relationship with

Neglectella peisonis

. Further morphological comparisons combined with phylogenetic results revealed three different morphological types in

Neglectella

. The new type represented by our new species may represent a transitional morphology in intermediate taxonomic position between the other two types. The diversity of morphological types in

Neglectella

suggests that further unknown species of this genus are likely to be discovered in the future. More collections and DNA sequence data will be needed in the future for this genus.
