Description: Erect thallus, up to 30 cm tall, radially branched many times, attached by small prostrate parts of axis having unicellular rhizoids but without trichoblasts; axes polysiphonous, with monopodial growth, cylindrical and uncorticated; segments with 7 pericentrals, each segment with a branched, persistent, pigmented trichoblast borne in a spiral on the axis; trichoblasts branch in a single plane. Lateral polysiphonous branches formed on trichoblast basal cells. Procarps borne on the 2nd cell of a trichoblast which remains smaller than vegetative ones; two sterile cell groups attached to supporting cell as well as the carpogonial branch which in B. australis has a 5th cell, attached to the basal cell of the carpogonial branch. Spermatangial capitula cylindrical, either replacing trichoblast or a proximal branch of trichoblast. Tetrasporangia borne spirally in stichidia bearing reduced trichoblasts; two pre-sporangial cover cells formed and a single tetrasporangium per segment; mature sporangia cause segments to become swollen.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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