Currently accepted name for the type species: Dasycladus vermicularis (Scopoli) Krasser
Original publication and holotype designation: Agardh, C.A. (1828). Species algarum rite cognitae, cum synonymis, differentiis specificis et descriptionibus succinctis. Voluminis secundi. Sectio prior. pp. [i]-lxxvi, [i]-189. Gryphiae [Greifswald]: sumptibus Ernesti Mauriti [Ernst Mauritius].
Precise date of publicationSeptember-December 1828
Taxonomic status: currently recognized as a distinct genus.

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.

Numbers of names and species: There are 9 species names in the database at present, of which 3 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
