Diagnosis:

Type species: Lyngbyopsis willei Gardner 1927. - Monospecific genus.

Descriptions:
Komárek (1992): Filamentous; filaments more or less parallely and densely joined in fascicles and perpendicularly oriented to the substrate, radially composed in macroscopic, hemispherical colonies or (later) in thick layers, attached to stones and sometimes incrusted, or covered by anorganic particles; filaments always with colourless, firm sheaths, which are joined to trichomes, often branched and anastomozing (only sheaths, not trichomes) and enveloping one, rarely two trichomes, opened at the ends, rarely ,crosswise lamellated. Trichomes isopolar, cylindrical, 5-8 μm wide, with or without slight constrictions at the cross walls, at the end not attenuated, with the end cell widely rounded, with thickened outer cell wall. Cells more or less isodiametric or slightly longer or shorter than wide, without aerotopes, olive-green or blue-green, slightly granular. Heterocytes and akinetes absent.

Genotype differences, molecular data:

Reproduction strategies, life cycles, cell division:
Komárek (1992): Cell division crosswise, perpendicularly to the long axis of a trichome, daughter cells grow up to the original size before the next division. All cells capable to divide. Reproduction by motile hormogonia, which escape from the open sheaths in the periphery of a colony.
