Description: Thallus unbranched unicell 3-6 cm tall, compact rhizoid, stalk bearing tightly packed whorls of ca. 12 thrice di- then trichotomously branched laterals. Calcification at base of lateral. Parietal chloroplasts numerous and discoid. Deep green solitary gametangium, a modified secondary lateral. Biflagellate gametes formed directly from gametangium which is initially uninucleate. Different from Batophora in compactness of whorls, single gametangium per lateral unit and the lack of cyst formation in gametangia. Gamete release occurs when gametangium still attached to thallus. Dasycladus tropical to warm temperate, known from Australia, Caribbean and Mediterranean Seas in shallow water on solid substrates on reefs, mangrove lagoons and canals. Most similar to Batophora and Chlorocladus, and these genera previously segregated into own subfamily.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
