The diversity of eukaryotic microorganisms is far from fully described, as indicated by the vast number of unassigned genotypes retrieved by environmental sequencing or metagenomics. We isolated several strains of unicellular green algae from algal biofilms growing on tree bark in a Southeast Asian tropical rainforest and determined them to be relatives of an unidentified lineage of environmental 18S rDNA sequences, thus uncovering its cellular identity.

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.

Obliquicauda gen. nov. (Trebouxiophyceae, Chlorophyta), including O. inflata sp. nov. and O. apiculata sp. nov.: foliicolous algae from Ficus leaves

Morphological, ultrastructural, and molecular phylogenetic investigations of two unidentified foliicolous algal strains in a tropical rainforest of China indicated that they differ from each other but cluster together and represent a new lineage of Trebouxiophyceae in the Choricystis/Botryococcus clade.

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.

Molecular Evidence for the Wide Distribution of Two Lineages of Terrestrial Green Algae (Chlorophyta) over Tropics to Temperate Zone

Phylogenetic analyses of 18S rDNA sequences from environmental clones and culture strains revealed a widespread distribution of two subaerial green algal lineages, Jenufa and Xylochloris, recently

Chloroplast phylogenomic analysis of chlorophyte green algae identifies a novel lineage sister to the Sphaeropleales (Chlorophyceae)

A chloroplast phylogenomic study advances knowledge regarding the circumscription and internal structure of the Chlamydomonadales, suggesting that a previously unrecognized lineage is sister to the Sphaeropleales.

Morphology and Phylogenetic Position of the Freshwater Green Microalgae Chlorochytrium (Chlorophyceae) and Scotinosphaera (Scotinosphaerales, ord. nov., Ulvophyceae)

The close relationship of the Scotinosphaerales with other early diverging ulvophycean orders enforces the notion that nonmotile unicellular freshwater organisms have played an important role in the early diversification of the Ulvophyceae.

Probing the Monophyly of the Sphaeropleales (Chlorophyceae) Using Data From Five Genes

A molecular phylogenetic study of 16 accessions representing all known families and diverse affiliated lineages within the order Sphaeropleales resolved Volvocales, algae possessing predominantly biflagellate motile cells with clockwise flagellar orientation, as the monophyletic sister lineage to Sphaerropleales, and an alliance of Chaetopeltidales, Chaetophorales,
