Description: Thallus unbranched unicell 6-7 cm tall with persistent compact whorls of 8 primary laterals each of which produces two tapered pod-shaped 0.8 cm long gametangial secondary laterals and a single thrice-branched sterile hair. Thallus and gametangia lightly calcified. H. wrightii with ca. 200 nuclei in cental siphon. Parietal chloroplasts numerous and discoid, pyrenoids absent; thylakoids not stacked into grana. Starch grains in both chloroplast and cytoplasm, the latter not membrane bound. Asexual reproduction unknown. Sexual reproduction involving whorls of gametangia overlapping vegetative branches from the base to the apex. Gametangia produce 100's of heavily calcified coalesced cysts which form biflagellate gametes; gametangia initially uninucleate, when mature with ca. 2000 nuclei.Halicoryne widely distributed in tropical to warm temperate Pacific including southern Japan, New Caledonia, Indonesia. Plants firmly attached to solid substrata such as stones, coral rubble. Most similar to Acetabularia, and these genera previously segregated into own subfamily

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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