Daedalea quercina

Daedalea quercina


Common Name: Thick-Maze Oak Polypore


Substrate: Oak Logs

Location: Anywhere downed trees are

Spore Color: White

Pore Color: White


This mushroom is not much to look at until you flip it over. The top has your standard shades of brown, but the underside has a pore surface where the pores tend to come together forming a maze-like pattern. This species is usually very difficult to remove from the log it is attached to. If you manage to get it off, one other way to ensure you have the right species is that this mushroom is not flexible. It should not bend.


This mushroom is called the Thick-Maze Oak Polypore because it has a sister species, Daedalea confragosa, that is much more flexible. You could actually bend it without snapping the mushroom. Another mushroom may also appear similar, Lenzites belutina - Gilled Polypore - but as the name suggests, the pores on the undersurface form a gill-like surface rather than a maze.
