Fourteen exceptionally preserved mushroom fossils from the Early Cretaceous were uncovered in Brazilian sedimentary rocks. Named Edaphagaricites conicus, the species shows detailed gills, stems, and cap structures resembling today’s Russulaceae (like brittlegills and milkcaps). Dating to about 113 million years ago, it stands as one of the two oldest known gilled mushrooms, providing a rare calibration point for fungal evolution and a deeper glimpse into the early history of Agaricomycetes.
