Description: Thalli erect, unbranched or more rarely bifurcate, dark green fronds to 10 cm high and 3 mm wide. Central axis siphonous to 550 &m diam. with crowded whorls of 9-12 branches, each branch with 5-7 series of segments; basal segment with 4 branches and giving rise to two or three segments terminally; tertiary segments giving rise to a 3 or 4 segment long simple or branched hair. Hairs and upper segments of whorl branches deciduous. Asexual reproduction unknown. Sexual reproduction by means of iso?gametes formed in operculate, uncalcified, spherical to obovoid cysts 90-140 &m in diam. Gametangia 380-680 &m diam., single at apex of basal segment of whorl branch; up to 90 cysts per gametangium. Details of gamete morphology and sexual process unknown; presumably similar to Acetabularia. Chlorocladus poorly known; found in tropical waters of western Pacific; C. australicus in Northern Australia, C. philippinensis in the Philippines. Found in sand or mud over coral substratum or on rock below low tide line. Chlorocladus included with Dasycladus by some authors; differs in presence of operculate cysts and regular development of segmented hairs on whorl branches; both included in same subfamily with Batophora. Taxonomic distinction of two species requires further study.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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