Description: Thalli comprising small tufts of irregularly branched filaments. The most characteristic feature is the formation of relatively short hyaline hairs with slightly swollen base, separated by a wall from ordinary cell below. Vegetative cells with a parietal, somewhat reticulate chloroplast. Sporangia of same shape and size as vegetative cells, except for exit papilla formed through basal part of hair if one present in vegetative condition. Swarmers, produced after sequential division of protoplast, either quadriflagellate zoospores or biflagellate, probable anisogametes. Unilateral germination into plants similar to parental plants. Recorded only once epiphytic on Cladophora sp. in the Caribbean.

Verification of Data

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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