This handout image released by the Swedish Museum of Natural History on April 24, 2017 shows an X-ray tomographic rendering of a bubble in 2.4 billion-year-old lava containing mycelial fossils. The bubble is 0.8 mm in diameter. Fossils accidentally discovered in South Africa are probably the oldest fungi ever found by a margin of 1.2 billion years, rewriting the evolutionary story of these organisms which are neither flora nor fauna, researchers said on April 24, 2017. / AFP PHOTO / Swedish Museum of Natural History / Stefan Bengtson / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / SWEDISH MUSEUM OF NATURAL HISTORY / STEFAN BENGTSON" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS
