Laetiporus sulphureus
A bright sulphur-yellow and orange bracket fungus that causes a brown cubical heart rot in living and dead hardwoods, especially oak. It is a popular wild edible, but it is hard to cultivate, and home cultivation usually means inoculated oak logs rather than indoor blocks. Several look-alike species exist, some of which cause stomach upsets.
Where it grows wild
It is parasitic and saprobic on living and dead hardwoods, mainly oak, but also cherry, willow, poplar, locust, beech and pear, and occasionally conifers. It fruits in overlapping shelves on trunks and logs, usually well above ground. It rots the heartwood, turning it reddish-brown and brittle.
Mostly lowland. Only 3 records had an elevation (68–360 m, median 98 m).
