Diagnosis: The thalli of mature plants are cushion-shaped, composed of prostrate and branched filaments. The prostrate system consists of rounded sarcinoid-like packages.

Reproduction occurs by vegetative division and by zoospores.

The genus differs from similar genera by SSU-ITS sequences.

The type species (designated herein): Lithotrichon pulchrum Darienko et Pröschold sp. nov.
