Description: Major characteristic for this genus, the presence of lateral, true phaeophycean hairs on the erect filaments as well as from the basal system. Erect filaments are uniseriate, monopodially branched with relatively short laterals. Laterals are almost perpendicular to the main axis. Growth is diffuse intercalary. Plurilocular sporangia on the erect filaments formed by transformation of the short laterals. Unilocular sporangia have only been observed in G. ramosum; they are placed basally on the erect filaments. Pedersen (1981b) reported on the life history of G. alariae being of the direct type. The presence of true phaeophycean hairs on the erect filaments makes placement in the Ectocarpaceae questionable.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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