Request PDFDescription: Unicellular, free-living, solitary, non-motile organisms 7-19 _m long and 3-9 _m wide. Cells in the form of a short truncated prism to rounded cylindrical at the base and truncated or slightly convex at the apex, appearing rounded in the basal portion, in optical section and bluntly triangular in the region of the apex. At the margin of the apex are inserted three short or long spines to 70-80 _m long, these fragile or firm, slightly divergent or nearly parallel to each other and to the long axis of the cell. They correspond to each of the poles of the apex. They are smooth and quite stiff. Cell wall possibly ornamented. Chloroplasts one or many and parietal. Asexual reproduction has not been observed. Endogenous cysts with a cell wall comprised of two equal or unequal valves and short spines or warts known in one species. Schilleriella grows in coastal regions of the Adriatic mostly in nearly freshwater. Species distinguished based on firmness or fragility of spines, their length, and on cell dimensions. Chrétionnot-Dinet considered Schilleriella a poorly preserved form of the diatom genus Chaetoceros.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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