Gilled fungi with laterally-attached fruiting bodies are classified as pleurotoid (Gr.
: pleurē + ōtos + -oid, literally "side-ear form" or "having the likeness of Pleurotus ssp.").
Pleurotoid fungi are typically wood-decay fungi and are found on dead and dying trees and coarse woody debris.
The pleurotoid form is polyphyletic, having evolved a number of times within the Basidiomycota.
[1] Many species of pleurotoid fungi are commonly referred to as "oyster" mushrooms.
