Adlafia is a genus characterized by small cells, usually less than 25 µm in length. The valve shape is linear to linear-lanceolate. Adlafia is distinguished by features terminal nodules that are unilaterally bent and strongly angular. The shape of the valve ends may be blunt, rostrate, or subcapitate. Striae are radial and composed of areolae covered by hymenes. The striae are uniseriate. Species inthis genus are also characterized by the solitary growth of cells.
Adlafia is comprised of species formerly in Navicula, including A. muscora (Kociolek & Reviers) Moser, and A. bryophila (Petersen) Moser. Adlafia species are characteristic of aerophilic habitats, especially growing in and around wet mosses. Some species are found in oligotrophic lakes. In general, species of Adlafia are widespread across North America, but often rare within a given assemblage.
