Loriella Borzì, 1892

Holotype species: Loriella osteophila Borzì

Original publication and holotype designation: Borzì, A. (1892). Alghe d'acqua dolce della Papuasia raccolte su cranii umani dissepolti. Nuova Notarisia 3: 35-53.

Description: Thallose; thallus attached to the substrate, grass-like, composed of more or less rigid, erect, regularly and repeatedly pseudodichotomously divaricated free filaments. Trichomes always uniseriate, constricted at the crosswalls, 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,funnel-like with diverging layers, but not widened at the ends, encrusted by lime; the ends of layers causes the transverse lamellation on the sheath surface. Heterocytes present, solitary, intercalary, 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 the vegetative cells, but with thin cell wall (?). 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. Grows aerophytically, described from wet human bones in Melanesia and found also on limestone substrate in Papua New Guinea. Reports from a polluted river near Berlin (central Europe) are very probably incorrect.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
