Laetiporus sulphureus is the eastern species of the “Chicken Mushroom.’  There are at least five other species, each with its own ecology. L. sulphureus is an annual heart-rot fungus causing cubical brown-rot.  It is found on the trunk of standing or fallen trees. The similar-looking white-pored Laetiporus cincinnatus is a root and butt-rot fungus and is always found at the base of infected trees.

It is a saprobe and may also be s.w. parasitic as it can be found on living as well as fallen trees.

They are best when fresh and young and when the leaves are soft. L. cincinnatus, being thinner and softer in texture, is often the preferred variety for culinary purposes.  Either polypore is an excellent vegetarian substitute for chicken.
