Hydrosera is a genus of diatom described in 1858 by George Charles Wallich. Hydrosera exhibits valve margins resembling two superimposed triangles and the presence of a distinct rimoportula. Hydrosera also feature porefields at the three poles of one of the apparent triangles, which contain pseudocelli.[1] Dead Hydrosera create siliceous oozes.[2]
Hydrosera grows in the streams of southern coastal areas and tropical islands.[1]
