Request PDFDescription: Thalli green or olivaceous, highly multicellular, forming lobed or unlobed prostrate thalli to ca 50 cm diameter and 1-3 mm thick with many thousands of cells in mucilaginous matrix; cells dispersed or grouped in 2s or 4s, more numerous near thallus margin. Species with or without conspicuous surface striations and with or without striations or fibrous structures within mucilaginous matrix. Cells spherical, 5-15 µm in diameter, single or in pairs, with thin cell walls, and usually widely dispersed in matrix with cells more dense toward upper surface. Cells uninucleate; single chloroplast cup-shaped and parietal without pyrenoid and stigma. Asexual reproduction, flagellated stages and sexual reproduction unknown.

Taxonomic status: This name is of an entity that is currently accepted taxonomically.
Most recent taxonomic treatment adopted: Zechman, F.W., Verbruggen, H., Leliaert, F., Ashworth, M., Buchheim, M.A., Fawley, M.W., Spalding, H., Pueschel, C.M., Buchheim, J.A., Verghese, B. & Hanisak, M.D. (2010). An unrecognized ancient lineage of green plants persists in deep marine waters. Journal of Phycology 46(6): 1288-1295.
Comments: Palmophyllum species are found subtidally in marine environments in warm temperate to tropical waters; reported from the Mediterranean and Caribbean Seas and from the Kermadec and Poor Knights Islands of New Zealand. Several additional species described from Mediterranean; however, Feldmann (1937) considered these as varieties of P. crassum. Ultrastructural studies of P. umbracola confirm the absence of a pyrenoid and a stigma. Cells with one (occasionally 2-3) prominent dictyosomes. An abundant orange pigment present, but remains to be characterized. Family assignment will remain provisional until flagellated stages and reproductive morphology have been studied.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
