Pantocsekiella, a new centric diatom genus based on morphological and genetic studies
The new genus Pantocsekiella is described, which has distinctive morphological features: striae unequal in length, central area without areolae, and several Lindavia taxa are transferred into it.
Pliocaenicus bolshetokoensis – a new species from Lake Bolshoe Toko (Yakutia, Eastern Siberia, Russia)
A new species from the diatom genus Pliocaenicus Round & Håkansson is described from Yakutia (Eastern Siberia, Russia) as Pliocaenicus bolshetokoensis sp. nov., on the basis of light and scanning
Materials on the flora of diatoms (Centrophyceae) from lakes of the Baikal Region and Transbaikalia
The species composition of Centrophyceae (Bacillariophyta) in the phytoplankton of nine lakes in the Baikal Region and Transbaikalia was studied using electron microscopy (SEM) methods. Nineteen
Morphological variability, taxonomy, and distribution of Cyclotella bodanica Eulenstein (Bacillariophyta) in Russia
The morphology of six populations of a rare freshwater species of diatoms from lakes of different geographic location is studied using SEM techniques and it is shown that some features vary to a greater extent than is indicated in the literature.
Comparative morphological characteristic of diatoms of genus Hannaea Patrick of the two largest lakes of the Baikal rift zone with a description of the new species
The comparative morphological characteristics of fragilaroid diatoms of genus Hannaea from lakes Baikal and Khubsugul, based on the results of light and electron microscopy, as well as new data on the study of type material H. baicalensis, show high similarity with H. inaequidentata.

A study of the widespread centric diatom Cyclotella choctawhatcheeana has revealed the variability of qualitative and quantitative morphological diagnostic features, as well as the presence of
Morphology, taxonomy and distribution of Stephanodiscus triporus (Bacillariophyceae) and related taxa
There is a continuum of variation between S. triporus and S. vestibulis (in diameter, the number and morphology of the striae, the position of the valve face fultoportula with three satellite pores, the presence of a vestibulum having more or less the same shape), and it is suggested that they are conspecific.
Light and electron microscopy study of Cyclotella ocellata Pantocsek (Bacillariophyta) species from Lake Khubsugul (Mongolia) revealed an appreciable morphological variability of qualitative and quantitative features along with the occurrence of colonies.
