At a time when the tallest trees stood just a few feet high, giant "mushrooms" towered over the landscape.

That's the finding being reported by new a paper appearing in the May issue of the journal Geology.

The study adds to the quest to solve a long-standing scientific puzzle: the true nature of a fossil that was the world's largest organism from about 420 million to 370 million years ago.

Years ago, I heard a report on the radio about the largest living organism being some giant fungus growing in some forest area over square miles.  Apparently considered a single organism, as opposed to a colony of separate organisms.  Ostensibly, this fossil is of something similar.
