Codiophyllum J.E.Gray, 1872

Holotype species: Codiophyllum natalense J.E.Gray

Original publication and holotype designation: Gray, J.E. (1872). On Codiophyllum, a new genus of unicellular green algae from Port Natal. Annals and Magazine of Natural History Ser. 4, 10: 139-141, Plate IX.

Description: Subcylindrical to variously fluted and flattened "woody" stalks with perennial growth rings, arising from a massive holdfast, unbranched below, fanning out above into dichotomous blades or into a number of irregular arms from which a lamellar mesh of terete, anastomosing filiform branches spread out. Medulla with many periclinal filaments. Refractive medullary cells present in some species. Cortex of progressively smaller isodiametric cells toward cuticle. Secondary pit connections and cell fusions numerous. Some species associated with sponges. Reproductive structures in leafy, branched proliferations borne on surface of veins and stalks of blades. Ampullae branched to three or four orders. Carpogonial branch 2-celled, on the primary ampullar filament. Hypogynous cell bearing a short lateral filament. Auxiliary cell in a separate ampulla, the basal cell of a secondary ampullar filament. A single outwardly directed gonimoblast initial producing a compact cystocarp with many small carposporangia. Small auxiliary fusion cell formed. Pericarp of ampullar and adjacent cortical cells. Carpostome absent. Spermatangia undescribed. Tetrasporophyte isomorphic. Tetrasporangia small, cruciate, attached subbasally 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
