Phycological research Liu et al. (2023) report the discovery of approximately 1.64-billion-years-old multicellular fossils from the Chuanlinggou Formation (China), providing evidence that the multicellular algae had already originated by the late Paleoproterozoic. A study on deep-sea organic-rich deposits from the Waiheke Island (New Zealand) is published by Grasby et al. (2023), who interpret the studied deposits as lamalginites formed from phytoplankton, providing evidence of an open-ocean algal bloom during the Permian-Triassic transition. A study on the fossil material of rhodolith-forming coralline red algae from the Miocene Long Formation from the Little Andaman (India), interpreted as indicative of high carbonate production in the northeastern Indian Ocean during the Serravallian, is published by Dey et al. (2023).

The type species is S. pliocenicus. Mycological research New information on the anatomy of Sporocarpon asteroides, inferred from new specimens from the Lower Coal Measures (United Kingdom), is presented by Krings et al. (2023), who interpret S. asteroides as a unisporic sporocarp with a parenchyma-like peridium, probably with affinities to the Glomeromycota. The first finding of a mycelium of a putative nematophagous fungus belonging to the group Basidiomycota from the Cretaceous of North Asia is reported from the Santonian Yantardakh Lagerstätte (Taymyr, Russia) by Sukhomlyn & Perkovsky (2023). Kutchiathyrites eccentricus is transferred to the modern genus Mycoenterolobium by Worobiec, Worobiec & Liu (2023) on the basis of study of the fossil material from the Neogene deposits of the Gray Fossil Site (Tennessee, United States) and the Bełchatów Lignite Mine (Poland).

Cnidarian research Pywackia baileyi, originally classified as a bryozoan, is reinterpreted as a cnidarian by Hageman & Vinn (2023). Conulariid specimens preserved with muscle bundles and a possible gastric cavity are described from the Carboniferous Wewoka and Graham formations (Oklahoma and Texas, United States) by Sendino et al. (2023). Van Iten et al. (2023) describe soft parts of two specimens of Metaconularia manni from the Silurian (Sheinwoodian) Scotch Grove Formation (Iowa, United States), and interpret their anatomy as indicating that at least one species of conulariid might have lacked a free-living, medusoid life phase, and might have produced eggs and sperm within the body of the sessile polyp. Redescription of Conicula striata is published by Zhao et al. (2023), who report that C. striata had features of both anthozoans and medusozoan polyps, and recover it as a stem-medusozoan, potentially indicating that medusozoans had an anemone-like ancestor. Zhang et al. (2023) describe new fossil material of Qinscyphus necopinus from the Cambrian (Fortunian) Kuanchuanpu Formation (China), including the whole apical part and providing complete information on the morphology of Qinscyphus. Plotnick, Young & Hagadorn (2023) classify Essexella asherae as a sea anemone, and reinterpret Reticulomedusa greenei as the pedal or oral disc of E. asherae.
