Description: Unicellular, solitary, attached organisms often forming tree -like colonies up to 1 cm diameter, and producing at one extremity a robust, mucilaginous stipe. Stipe to 20 &m long, often enlarged at the base in contact with the substratum, straight or sometimes slightly curved and more or less stratified. Cells 5-18 &m long and 3-11 &m wide, spherical, ellipsoidal, oval or pyriform. Cell wall thin to thick, sometimes reddish and with pores at the end in contact with the pedicel. The mucilage is excreted by the pores. One to four or more chloroplasts present, these cup shaped or discoid and parietal, without pyrenoids. Storage products of oil granules and lipids sometimes red colored. Asexual reproduction by autosporulation. Autospores (2 to 8 per mother cell) release as a group and attach to the maternal stipe thus producing a tree like colony. Some species produce very amoeboid zoospores with one or two chloroplasts. Zoospores uniflagellate or with two unequal flagella, the longer of which is one and half times as long as the cell. Gloeopodium in fresh or brackish water; known from Europe and the USA. Species distinguished based on cell dimensions and shape, the importance of the stipe, number of chloroplasts and the nature of the cell wall.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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