Urban species #251: Oak maze-gill
Daedalea quercinaIn temperate places where oak trees grow, they die and their wood is decayed by the oak maze-gill. Other fungi may do it, too, but it's the only thing that
Daedalea quercina does. This mushroom will not appear on other dead trees, though a thin-fleshed look alike,
Daedaleopsis confragosa, will grow on dead
birches and
willows. Though called a maze-gill, the spore-bearing surface technically consists of pores, and this fungus is in the same family as the "polypore" mushrooms, such as
Polyporus squamosus (
dryad's saddle). The pores are elongated into a distinctive maze-like pattern. Its scientific name alludes to Daedalus, the designer of the labyrinth, and the "quercina" part refers to oak itself (
Quercus is the Genus name for oak trees). Oak maze-gill is leathery and perennial, and can be found year-round for many seasons, until it finally turns black and rots away itself.
