Abstract
A new Microcostatus species was found during a study focusing on diatoms present on soils and among terrestrial mosses. Unlike most known European species of this genus, it has easily distinguishable striae under the light microscope and a distinct central area. Additionally, the newly described species shows lack of conopeum and pseudoconopeum. A detailed morphological characterisation using light and scanning electron microscopy of a new species from the genus Microcostatus and comparison to the most similar taxa are given.
