Cirrulicarpus Tokida & Masaki, 1956

Holotype species: Cirrulicarpus gmelinii (J.V.Lamouroux) Tokida & Masaki

Currently accepted name for the type species: Cryptonemia palmetta (S.G.Gmelin) Woelkering, G.Furnari, Cormaci & McNeill

Original publication and holotype designation: Tokida, J. & Masaki, T. (1956). Studies on the reproductive organs of red algae II. On Erythrophyllum gmelini (Grun.) Yendo. Bulletin of the Faculty of Fisheries Hokkaido University 7: 63-71.

Description: Flat, foliose, dichotomously to polychotomously branched to several orders. Ultimate segments flabellate, cordate or reniform, cleft. Subultimate parts of blade frequently wearing away to leave a thickened stem with or without torn fragments of thallus still attached. Medulla of fusiform cells. Refractive cells present, elongate, with spike-like processes. Cortex of isodiametric to elliptical cells, progressively smaller toward cuticle. Single 3-celled carpogonial branch borne on lobed supporting cell, usually with two lobed subsidiary cells. After fertilization, carpogonial fusion cell involving supporting and subsidiary cells initiating nonseptate connecting filaments that contact a separate auxiliary cell, which bears a carpogonial branch and subsidiary cells. Gonimoblast filaments developing from connecting filament and auxiliary cell and radiating through thallus. Clusters of carposporangia developing near apices of gonimoblast filaments, producing a diffuse, ring-like cystocarp. Carpostome absent. Spermatangia undescribed. Tetrasporophyte isomorphic. Tetrasporangia irregularly cruciate, intercalary in cortex.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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