Nomenclatural notes
Perhaps synonymous with Carradoriella P.C.Silva, "... but the two may ultimately resolve as sister genera' (Choi et al. 2001: 1474). - (26 Jan 2017) - M.D. Guiry

Description: Plants solitary, epiphytic or saxicolous, polysiphonous; holdfasts of tightly clumped rhizoids cut off from basal pericentral or cortical cells; pericentral cells four to nine, ecorticate or corticate; branches mostly exogenous, some lateral branches cicatrigenous, sometimes arising in connection with trichoblast; trichoblasts moderately developed on apex of branchlets, one on each segment, spirally arranged, slender, elongate, simple or forked, deciduous, often leaving conspicuous scar-cells; procarps with three-celled carpogonial branch, cystocarps scattered on branchlets, not aggregated, narrow globose or ovate, very shortly pedicellate; spermatangial branches arising from one fork of trichoblast, cylindrical, sometimes with sterile tip; tetrasporangia tetrahedral, forming spiral series in upper branchlets

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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