**Microfissurata** gen. nov. (Bacillariophyta), a new diatom genus from dystrophic and intermittently wet terrrestrial habitats
Abstract: A new freshwater benthic diatom genus, Microfissurata gen. nov., was identified from light and scanning electron micrographs. The most characteristic morphological feature (referred to also by the name of the new genus) is the structure of the striae/alveoli, which are simple, mostly unint...
