Mystery fossil turns out to be giant fungus

Scientists have identified the Godzilla of fungi, a giant, prehistoric fossil that has evaded classification for more than a century, U.S. researchers said on Monday.

A chemical analysis has shown that the 20-foot-tall (6-metre) organism with a tree-like trunk was a fungus that became extinct more than 350 million years ago, according to a study appearing in the May issue of the journal Geology.
