Diagnosis:

Type species: Loriella osteophila Borzì 1892

Descriptions:
Komárek (1992): Thallous; thallus attached to the substrate, grass-like, composed from more or less rigid, erected, regularly and repeatedly pseudodichotomously divaricated free filaments. Trichomes always uniserial, constricted at the cross walls, composed of short, more or less isodiametric and barrel-shaped cells, with rounded-conical apical cells, true-branched (V-type). Sheaths thick, not confluent, distinctly limited, intensely lamellated, funoel-like with diverging layers, but not widened at the ends, incrusted by lime; the ends of layers causes the transverse lamellation on the sheath surface. Heterocytes present, solitary, intercalar, rarely terminal at the ends of branches; sometimes they occur near the bases of branches. Akinetes develop occasionally in rows, oval or ellipsoidal, slightly larger than are the vegetative cells, but with thin cell wall (?).

Genotype differences, molecular
data:

Reproduction strategies, life cycles, cell division:
Komárek (1992): Cell division crosswise. Reproduction by 10-14-celled hormogonia, separating from ends of trichomes (branches). Hormogonia divide sometimes during germination in two (or more) segments; the first branching follows soon after germination of hormogonia.

Notes to taxonomy, misinterpretations:

Ecology, ecophysiology, ecological significance:
Komárek (1992): Grows aerophytic, described from wet human bones in Melanesia and found also on limestone substrate in Papua New Guinea. The data from a polluted river near Berlin (central Europe) are very probably incorrect.
