Revision of the pantropical genus Brasilonema (Nostocales, Cyanobacteria), with the description of 24 species new to science Open
Brasilonema was separated from Scytonema only in 2007 (Fiore et al. 2007). It possesses diagnostic morphological characteristics such as vacuole-like structures in older cells, frequent purple pigmentation of cells, rare false branching an…

A survey of ‘Candidatus Phytoplasma pyri’ isolates in the Czech Republic based on imp gene genotyping Open
‘Candidatus Phytoplasma spp.’ are pathogenic bacteria that infect many plant species. ‘Candidatus Phytoplasma pyri’, one of the members of the 16SrX group causes pear decline disease that adversely affects pear crops. To describe the preva…

Neotypification of Pleurocapsa fuliginosa and epitypification of P. minor (Pleurocapsales): resolving a polyphyletic cyanobacterial genus Open
Strains with complete morphological match to Pleurocapsa fuliginosa and P. minor were isolated from Oahu, with another strain matching P. minor isolated from a wet rock face in Utah. Phylogenetically these baeocyte and pseudofilament produ…

Revision of the Synechococcales (Cyanobacteria) through recognition of four families including Oculatellaceae fam. nov. and Trichocoleaceae fam. nov. and six new genera containing 14 species Open
A total of 48 strains of thin, filamentous cyanobacteria in Synechococcales were studied by sequencing 16S rRNA and rpoC1 sequence fragments. We also carefully characterized a subset of these by morphology. Phylogenetic analysis of the 16S…

Identification of 17 ‘ <i>Candidatus</i> Phytoplasma pyri’ genotypes based on the diversity of the <i>imp</i> gene sequence Open
Phytoplasmas of the apple proliferation group cause diseases in various fruit trees, mainly apples, pears and apricots. Immunodominant membrane protein, or ‘Imp’, shows high inter‐ and intraspecies gene variability, and is thus frequently …

Highly divergent 16S rRNA sequences in ribosomal operons of Scytonema hyalinum (Cyanobacteria) Open
A highly divergent 16S rRNA gene was found in one of the five ribosomal operons present in a species complex currently circumscribed as Scytonema hyalinum (Nostocales, Cyanobacteria) using clone libraries. If 16S rRNA sequence macroheterog…

<i>Cyanomargarita</i> gen. nov. (Nostocales, Cyanobacteria): convergent evolution resulting in a cryptic genus Open
Two populations of Rivularia ‐like cyanobacteria were isolated from ecologically distinct and biogeographically distant sites. One population was from an unpolluted stream in the Kola Peninsula of Russia, whereas the other was from a wet w…

A revision of the genus Geitlerinema and a description of the genus Anagnostidinema gen. nov. (Oscillatoriophycidae, Cyanobacteria) Open
The simple filamentous cyanobacterial genus Geitlerinema is heterogeneous. At least two distinct phylogenetic clades can be derived from the set of most common freshwater Geitlerinema species. Our revision is based on the original descript…

New and unusual species of cyanobacteria, diatoms and green algae, with a description of a new genus Ekerewekia gen. nov. (Chlorophyta) from the table mountain Churí-tepui, Chimantá Massif (Venezuela) Open
The unique character of biotas on table mountains (tepuis) is well documented for macroscopic organisms. However, much less is known about the microorganisms inhabiting these unusual and diverse biotopes. Previously, new algal and cyanobac…

Roholtiella, gen. nov. (Nostocales, Cyanobacteria)—a tapering and branching cyanobacteria of the family Nostocaceae Open
A total of 16 strains phylogenetically placed within the Nostocaceae were found to possess morphological features of the Rivulariaceae and Tolypothrichaceae (tapering trichomes and single false branching, respectively) in addition to their…

Seven new species of <i>Oculatella</i> (Pseudanabaenales, Cyanobacteria): taxonomically recognizing cryptic diversification Open
A total of 27 strains of Oculatella were isolated, characterized and sequenced, and analysed phylogenetically with an additional environmental clone from the Atacama Desert and 10 strains isolated and sequenced by others. The strain…
