The Watanabea clade of the Trebouxiophyceae included mostly unicellular coccoid microalgae that thrived in various terrestrial microhabitats. [] Key Result The four strains investigated formed two species, P. laureanum and P. lobatum, which...

Phyllosiphon duini sp. nov. (Trebouxiophyceae, Chlorophyta), a Species Isolated from a Corticolous Phototrophic Biofilm

Three novel species of coccoid green algae within the Watanabea clade (Trebouxiophyceae, Chlorophyta).

Three new lineages of Trebouxiophyceae are revealed: the novel genus and species Mysteriochloris nanningensis gen. et sp.

Polulichloris henanensis gen. et sp. nov. (Trebouxiophyceae, Chlorophyta), a novel subaerial coccoid green alga

Molecular phylogenetic analyses indicated that this coccoid green alga represents a new lineage of the Watanabea clade (Trebouxiophyceae, Chlorophyta) and is described as a new genus and species, Polulichloris henanensis, gen. et sp.

Phyllosiphon ari sp. nov. ( Watanabea clade, Trebouxiophyceae), a new parasitic species isolated from leaves of Arum italicum (Araceae)

Phylogenetic differentiation of Phyllosiphon taxa, correlated with host specificity to different genera of the Araceae, suggests concerted host-pathogen co-evolution driving species diversification within this peculiar green algal lineage.

A new species Jenufa aeroterrestrica (Chlorophyceae incertae sedis, Viridiplantae), described from Europe

  • Biology
  • 2015
This paper describes and characterize a new species of the genus Jenufa, J. aeroterrestrica, which was identified in five samples of corticolous microalgal biofilms collected in Europe, and indicates that the newly described species frequently occurs in temperate and sub-Mediterranean European subaerial bio Films, such as those occurring on tree bark or surfaces of stone buildings.

Watanabeales ord. nov. and twelve novel species of Trebouxiophyceae (Chlorophyta)

The Watanabea clade is a group in the Trebouxiophyceae of Chlorella‐like taxa, which are predominantly solitary and terrestrial, and is separated into four groups during the phylogenetic analyses, but no regular differences in habitats or morphology could be used as the morphological basis to split Watanabales into the four groups.

Molecular diversity of green corticolous microalgae from two sub-Mediterranean European localities

The samples taken from oak trees were more diverse in their OTU composition than those taken from pine trees, but the average phylogenetic distances of OTUs in samples did not differ between the host tree taxa, indicating that habitat filtering is important for the distribution of individual microalgal phylogenetic taxa.

Lunachloris lukesovae gen. et sp. nov. (Trebouxiophyceae, Chlorophyta), a novel coccoid green alga isolated from soil in South Bohemia, Czech Republic

The phylogenetic position, morphology and ultrastructure of the strain CCALA 307 previously identified as Coccomyxa cf.

New Species of Chloroidium (Trebouxiophyceae, Chlorophyta) from East Asia

Three strains of coccoid green alga isolated during a study of soil algae in the temperate monsoon climate zone of Asia are described here as a new species, Chloroidium orientalis, one of the most species-rich and widely distributed members of the order.

Phylogenic Diversity and Taxonomic Problems of the Dictyosphaerium Morphotype within the Parachlorella Clade (Chlorellaceae, Trebouxiophyceae)

This study focuses on the diversity of Dictyosphaerium morphotype algae within the Parachlorella clade, based on 42 strains from China and describes five distinct lineages, and examines the morphological features of these five lineages.



Leptochlorella corticola gen. et sp. nov. and Kalinella apyrenoidosa sp. nov.: two novel Chlorella-like green microalgae (Trebouxiophyceae, Chlorophyta) from subaerial habitats.

This study provides a detailed characterization of two strains of microalgae isolated from tree bark in the Mediterranean, described as representatives of a novel species in a new genus, Leptochlorella corticola gen. et sp.

Phylogenetic relationship of Chlorella and Parachlorella gen. nov. (Chlorophyta, Trebouxiophyceae)

It was shown that morphological criteria traditionally used for classification in Chlorellaceae are burdened with a high degree of phenotypic plasticity, which represents adaptations to environmental factors in order to optimize floating in the water column and to resist grazing pressure.

Kalinella bambusicola gen. et sp. nov. (Trebouxiophyceae, Chlorophyta), a novel coccoid Chlorella‐like subaerial alga from Southeast Asia

A new subaerial Chlorella‐like strain CAUP H7901 is studied and morphological, ultrastructural, and molecular phylogenetic investigations indicated that it represents a new lineage of the trebouxiophycean Watanabea clade, dissimilar from other members of this group.

Taxonomic reassessment of the genus Chlorella (Trebouxiophyceae) using molecular signatures (barcodes), including description of seven new species.

This study led to a new understanding of the evolution of morphology within the genus Chlorella and to an emendation of the generic description.


Three coccoid green algal strains belonging to a new genus and species are described and a new taxon, Marinichlorella kaistiae, is proposed, to describe these strains and classify them in the family Chlorellaceae.

Morphology and phylogenetic position of a trebouxiophycean green alga (Chlorophyta) growing on the rubber tree, Hevea brasiliensis , with the description of a new genus and species

A novel unicellular Chlorella-like green alga was isolated from the rubber tree (Hevea brasiliensis) and based on morphological features and phylogenetic position, a new genus Heveochlorella gen. nov. is proposed.

Generic concept in Chlorella-related coccoid green algae (Chlorophyta, Trebouxiophyceae).

Using a combined set of sequences of SSU and ITS regions of nuclear-encoded ribosomal DNA, the concept of the experimental algal genus Chlorella was evaluated and phylogenetic analyses showed that within the clade of 'true'Chlorella species, taxa with a mucilaginous envelope and colonial lifeform have also evolved.

Chloroidium, a common terrestrial coccoid green alga previously assigned to Chlorella (Trebouxiophyceae, Chlorophyta)

All Ch Lorella-like strains related to Chlorella saccharophila and C. ellipsoidea to the genus Chloroidium Nadson and to emend its diagnosis are proposed, as well as four new combinations of these species that are likely to be used as chemotaxonomic marker.

A novel species in the genus Heveochlorella (Trebouxiophyceae, Chlorophyta) witnesses the evolution from an epiphytic into an endophytic lifestyle in tree-dwelling green algae

Both an epiphytic and an endophytic lifestyle of tree-dwelling green algae can be observed in the genus Heveochlorella, and H. hainangensis is treated as a novel species.

Fine structure and phylogeny of green algal photobionts in the microfilamentous genus Psoroglaena (Verrucariaceae, lichen-forming ascomycetes).

The fine structure and two molecular markers of the photobionts of P. stigonemoides and P. epiphylla were investigated to report the first report of terrestrial "prochlorophytes" of terrestrial green algae or cyanobacterial colonies.
