Trypanochloris Geitler, 1935

Holotype species: Trypanochloris clausiliae Geitler

Original publication and holotype designation: Geitler, L. (1935). Trypanochloris, eine neue grüne Alge in den Schalen von Landschnecken und ihre Begleitflora. Biologia generalis 11: 135—148, 5 figs.

Description: Unicellular organisms up to 60 µm diameter. Young cells coarsely rounded, becoming stellate when adult with irregularly cylindrical, sometimes dichotomous prolongations radiating more or less from the region of the cell containing the nucleus. The cell wall is fine and cellulosic in nature. Chloroplast single forming a large parietal plate, folded at the margins and sometimes resembling a tube. Pyrenoids absent. Cytoplasm with globular oil bodies. Asexual reproduction by autosporulation which is not carried out by the entire cell. Autospores, extremely numerous and elongate ellipsoid to cylindrical (7.5-8 µm long and 2.7-3.8 µm wide). Cells developing into sporocytes up to 70 µm long and 30 µm diameter. After autospore release, cytoplasm at the extremities of the prolongations separate by a cell wall from the rest of the cell, thus producing a multicellular pseudothallus. Each of the new portions can develop into a sporangium. Sexual reproduction and cysts unknown. Trypanochloris develops exclusively in the peripheral layers of the shell of the genus Clausilia Draparnaud, a small terrestrial gastropod. Genus probably very widespread but reported only from central Europe.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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