Largest fungal fruit bodies

These fruit bodies have a wide variety of morphologies, ranging from the typical mushroom shape, to brackets (conks), puffballs, cup fungi, stinkhorns, crusts and corals.

Individual fruit bodies need not be individual biological organisms, and extremely large single organisms can be made up of a great many fruit bodies connected by networks of mycelia (including the "humongous fungus", a single specimen of Armillaria solidipes) can cover a very large area.

The largest identified fungal fruit body in the world is a specimen of Phellinus ellipsoideus (formerly Fomitiporia ellipsoidea).

This was markedly larger than the previously largest recorded fungal fruit body, a specimen of Rigidoporus ulmarius found in the United Kingdom that had a circumference of 425 cm (167 in).

Somewhere in his world travels, writer/naturalist/explorer Ivan T. Sanderson encountered reports of a species of fungi which "weigh a ton, and upheave large trees".
