Information kindly contributed by Wm. J. Woelkerling but may now be outdated.

Taxonomic status: This name is currently regarded as a synonym of Mesophyllum.

Comments: Mason (1953) explicitly designated P. conchatum as type species of Polyporolithon. Adey (1970: 23, 27) concluded from an examination of the lectotype specimen (TRH B17-2541; see Woelkerling et al. 2005: 340) of P. conchatum that it belonged to the genus Mesophyllum. This was subsequently confirmed by Athanasiadis et. al. (2004: 140-146, figs 54-91), who provided a detailed accounts of the lectotype and the species as a whole. Consequently, Polyporolithon Mason (1953) is treated as a heterotypic synonym of Mesophyllum Lemoine (1928).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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