Hydrologic reconstructions from North America are largely unknown for the Middle Miocene. Examination of fungal palynomorph assemblages coupled with traditional plant-based palynology permits delineation local, as opposed to regional, climate signals and provides a baseline study ancient fungas. Here, Fungi in Warmer World project presents paleoecology paleoclimatology 351 morphotypes 3 sites United States: Clarkia Konservat-Lagerstätte site (Idaho), Alum Bluff (Florida), Bouie River (Mississippi). Of these, 83 fungi identified extant taxa 41 newly reported Combining new paleoclimatic funga-based paleoclimate reconstructions, we demonstrate cooling hydrologic changes Miocene optimum Serravallian. In southeastern States, this is comparable that reconstructed pollen paleobotany alone. northwestern greater than indicated by other hydrology shifts seasonally, no dry season summer season. Our results utility fossil paleoecologic proxies warmer modern geological time intervals do not match "wet gets wetter, drier" paradigm. Instead, both plants show an invigorated hydrological cycle across mid-latitude America.
