Dictyochales (or Silicoflagellates) are a small group of unicellular heterokont algae, found in marine environments. ==Characteristics== In one stage of their life cycle, they produce a siliceous skeleton, composed of a network of bars and spikes arranged to form an internal basket. These form a small component of marine sediments, and are known as microfossils from as far back as the early Cretaceous.
