Request PDFDescription: Pseudofilamentous; pseudofilaments solitary, or in small irregular groups, cylindrical, isopolar, straight or slightly irregularly waved, with uniserially arranged, slightly separated from one another and in rows arranged cells within thick, homogeneous, colorless sheaths (according to original description = thickened cell-walls, 0.5-2 _m wide), which are closed at both ends. Cells not motile, cylindrical, isodiametric or longer than wide, elongated in the pseudofilament axis, enveloped probably by own gelatinous capsules (in spite of the indistinct sheath structures); cell content blue-green, differentiated in dark peripheral and light centroplasmic regions; in centroplasm are regularly 2 or 3 (-4) large spherical, dark blue and refractive granules. Cells divide crosswise . Reproduction probably by fragmentation of pseudofilaments (in original description is supposed the trichomal structure of pseudofilaments and fragments of pseudofilaments are described as "true hormogonia with conical rounded terminal cells", but not motile). Both species were described from one locality, wet wood and calcareous stones in a limestone cave, Hungary (Abaliget). Mixed among other algae.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
