Fusochloris Floyd, Watanabe & Deason, 1993, nom. inval.

Holotype species: Fusochloris perforata G.L.Floyd & Shin Watanabe

Description: Unicellular, solitary to clustered cells, 60 x 20 &m, fusiform, ellipsoid to ovoid or spherical, often asymmetrical, pointed to rounded at ends and usually attached to substratum at basal end. Nucleus single and central; chloroplast single and band shaped when young, becoming perforate with age. Asexual reproduction by aplanospores and zoospores. Zoospores 7-9 &m long and 3-4 &m wide, naked, without papilla. Zoospores biflagellate with flagella less than cell length. Flagellar apparatus with basal bodies displaced in counterclockwise orientation and not overlapping. Uninucleate with medium nucleus and contractile vacuole anterior. Chloroplasts single and extending full length of cell. Pyrenoid single with several traversing or circular thylakoids and with surrounding starch sheath of several particles. Fusochloris from freshwater; reported from Europe and North America. Culture of type species available from UTEX (as Characium). In culture growing in both liquid media and on agar. Taxonomic placement based on ultrastructural studies and these consistent with 18S rRNA sequences. Type species previously assigned to Chlamydopodium.Unicellular, solitary to clustered cells, 60 x 20 &m, fusiform, ellipsoid to ovoid or spherical, often asymmetrical, pointed to rounded at ends and usually attached to substratum at basal end.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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