Description: No description is provided at this time as the genus is currently referred to synonymy.

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 J. Woelkerling but may now be outdated.

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

Comments: Woelkerling (1991) concluded from a detailed study of the lectotype specimen (TRH A4-183; see Woelkerling et. al. 2005: 45-6) that Perispermon hermaphroditum, the type species of Perispermon, belongs to Lithophyllum (Family Corallinaceae). Consequently, Perispermon is treated as a heterotypic synonym of Lithophyllum. The status of L. hermaphroditum as a distinct species within Lithophyllum remains unresolved (Woelkerling 1991), but this does not alter the present status of the genus as a heterotypic synonym.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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