Generic name: DERMOCARPELLA Lemmermann, 1907. Bot. Jahrb. Syst. 38: 349.
Synonyms:
Diagnosis:
Type species:Dermocarpella hemisphaerica Lemmermann 1907
Descriptions:
Komárek & Anagnostidis (1998): Cells solitary or aggregated into groups, polarized, attached by one end to the substrate (by narrower,almost stalk-like, or widened, flattened basal part), hemispherical, oval or club-shaped, with thin or thick, sometimes lamellate, colourless sheaths.
Komárek (1992): Solitary cells or groups of cells, ,joined to the substrate. Cells more or less polarized, attached to the substrate by the gelatinous pad and by rounded basis; apical end +/- rounded; they are vase-like or club-shaped, narrowed or widened to the basis. Around cells firm, sometimes lamellated sheaths, which are later "opened" at the apical end (pseudovaginae). Cell content greyish blue-green, olive-green or pinkish red, finely granular, always without aerotopes.

Reproduction strategies, life cycles, cell division:
Komárek & Anagnostidis (1998): Reproduction by successive multiple fission of cells into baeocytes; first cell division always horizontal, perpendicular to the long vertical. axis, later in various planes. Baeocytes numerous, usually several times smaller than the original mother cell.
Komárek (1992):Reproduction by the rapid successive, total division of cells (multiple fission) into more small daughter cells (nanocytes). The first or several first division planes are oriented parallel with the substrate (perpendicularly to the vertical axis of the sessile cell). Immotile nanocytes escape from the pseudovagina through the apical opening. All cells divide obligatory only once into small nanocytes, which grow after joining to the substrate again into the +/- original size and shape (before the next division).

Ecology, ecophysiology, ecological significance:
Komárek (1992):Little known genus, found only from a few localities. Four species are marine, living attached to the higher littoral algae, two species are freshwater, known from Sphagnum leaves in alpine moors (Switzerland) and from periphyton on algae in a clear lake in Chatham islands (type species).
