New fossil find pushes age of terrestrial fungi back 60 million years, to the same era when green plants pulled themselves onto land
Fossils from a Wisconsin roadcut show clearly that fungi
and green plants moved from water onto land at about the same time, bolstering the theory that fungi
helped plants successfully invade the land. The newly discovered fossils - microscopic spores and th...
