Mycological research Xie et al. (2026) study fungal decay structures in Agathoxylon wood from the Upper Triassic (Norian) strata of the Löwenstein Formation (Germany), and interpret the studied wood as affected by both white rot and brown rot. Rea, Simpson & Wizevich (2026) study a sample of the ichnofossil Eopolis ekdalei from the Brushy Basin Member of the Morrison Formation (Utah, United States) preserved with plant, insect and fungal remains interpreted as suggesting that Eopolis ekdalei was produced by termite, as well as suggestive of fungal farming by termites during the Late Jurassic. Baker & Casadevall (2026) report evidence from the study the Cretaceous-Paleogene boundary section from the Denver Basin in Colorado (United States) indicative of elevated fungal abundance approximately 30,000 to 10,000 years before the Cretaceous–Paleogene extinction event and coinciding with the Poladpur phase of the Deccan Traps volcanism, as well as evidence of a fungal bloom in North America immediately after the Chicxulub impact. Worobiec, Worobiec & Liu (2026) report the discovery of spores assignable to the genus Potamomyces from the Pliocene strata from the Gray Fossil Site (Tennessee, United States), representing the northernmost record of the genus in North America known to date, and interpreted as consistent with environment with presence of a wetland ecosystem in a warm and humid climate.

Cnidarian research Bernad, Echevarría & Ros-Franch (2026) study the diversity dynamics of Conulariida throughout their evolutionary history, reporting evidence of decline of origination rates by the Late Ordovician. The oldest post-Ordovician coral reef in South China known to date is reported from the Silurian (Aeronian) strata of the Xiangshuyuan Formation by Yu et al. (2026). Wei et al. (2026) compare the diversification dynamics of photosymbiotic and nonphotosymbiotic corals throughout their evolutionary history, and find that photosymbiotic corals did not have a consistent evolutionary advantage over other corals throughout the Phanerozoic. Specimens of Montlivaltia with regular growth bands, interpreted as likely evidence of growth periodicities corresponding to lunar cycles nested within annual growth rhythms, are described from the Middle Jurassic strata from Lorraine (France) by Lathuilière (2026). Löser (2026) studies the composition of the assemblage of Hauterivian corals from the Yokonuma Formation (Japan), extending known temporal range of the genera Calamophylliopsis, ?Eohydnophora, Siderohelia and Palaeosiderofungia. Evidence of rejuvenescence in a Miocene coral Acanthastrea cf. polygonalis from the Band-e-Chakar Formation (Iran), interpreted as possible effect of thermal stress related to the Middle Miocene Climatic Optimum, is presented by Reuter et al. (2026). Moclán et al. (2026) study the biometric parameters and orientations of specimens of Cordubia gigantea from the Cambrian strata from the Constantina site (Torreárboles Formation; Spain), identify additional specimens at the studied site, and interpret the specimens from the studied aggregation as likely to have died during a mass mortality event. New fossil material of Octapyrgites elongatus, including the first known embryos of the species, is described from the Cambrian strata of the Yanjiahe Formation (Hubei, China) by Peng et al. (2026). Moreau et al. (2026) report the discovery of fossil material of Medusina atava from the strata of the Cham-el-Houa Siltstone Formation (Morocco), extending known geographical range of Permian freshwater medusoids into the equatorial zone.
