Description: Plants reach 20 cm in height and consist of flattened, generally subdichotomous blades, with or without marginal proliferations, borne on cylindrical stipes arising singly or in clusters from a discoid base. Spermatangial sori and procarps form either at apices of primary axes or in specialized outgrowths or bladelets, the cystocarps lacking an ostiole. Spermatangia are produced in ampullar-shaped pits (Dixon and Irvine 1977). Tetrasporangial nemathecia form on the surfaces of primary axes.

Comments: The iota carrageenans of the genus have been studied by McCandless et al. (1981) and Usov and Shashkov (1985). The genera Ozophora, Petroglossum and Phyllophora appear to be very closely related, and were all treated as belonging to Phyllophora by Kylin (1956). Abbott (1969) and Hollenberg (1943, 1945) distinguish Ozophora on the basis of its constant restriction of male and female structures to adventitious outgrowths, and Petroglossum by the restriction of its spermatangia to the major axes. Additional differences between the genera are discussed by Schneider and Searles (1976). Distribution: Most species occur in the north Atlantic of Europe and America, with others distributed in the north Pacific. Antarctic species are recorded (Neushul 1968) but are less well known.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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