Description: Thallus forming extensive fasciculate mats or small clusters, brown, brown-green, olive-green to darkgreen, dark blue-green to black. Filaments straight, isopolar, unbranched, (8-) 12-30 (-46) µm diam. Sheaths hyaline or bright yellow to yellow-brown, firm, thin or thick, sometimes lamellated. Trichomes not or slightly constricted at the cross-walls, not or slightly attenuated towards ends, (6.6-) 10-21 (-24) µm diam., sometimes some trichomes become contorted to originate the necridial regions. Cells 1.4-5.6 (-6) µm long, 1.2-11 times wider than long. Cross-walls often granulated, sometimes with large granules. Apical cells rounded, conical, conicalrounded, flat-rounded, truncate, rarely capitate, sometimes thickened, without calyptra. Hormogonia formed by fragmentation perpendicular to the longitudinal axis of the trichome helped by necridic cells, or in diagonal position, in this case helped or not by necridic cells.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
