Diatomeas (Clase Bacillariophyceae)Observ.
paul_broadyDescripción
Naviculoid diatom, very small, impossible to identify without cleaned frustules and access to a scanning electron microscope. Similar in shape and size to Navicula atomus but equally likely to be a species from a different genus, e.g. Achnanthes. Scrapings from exterior moist surface of a plant pot in a suburban garden.
