Abstract:

During a survey of a small freshwater pond enclosed by the Herbarium building of the National Botanic Garden of Belgium, two new species belonging to the genera Eunotia and Encyonopsis have been found. The morphology of both species is discussed using both light and scanning electron microscopical observations and compared with similar species. Eunotia belgica is similar to E. glacialifalsa but can be separated based on its valve dimensions (larger valve width), number of striae, the absence of the characteristic longer cell cycle stages of E. glacialifalsa and a different striation pattern. Encyonopsis horticola belongs to the E. microcephala complex but can be differentiated from other members of this complex by a combination of valve outline, striation pattern and areolae structure.
