Laetiporus

Laetiporus is a genus of fungi in the family Fomitopsidaceae. These fungi are commonly known as chicken-of-the-woods or sulfur shelf due to their bright orange or yellow coloration and their habitat on dead or dying trees. They are widely distributed in temperate regions of the world, occurring in North America, Europe, and Asia. Laetiporus species are polypores, meaning they produce their spores on pores on the underside of their fruiting bodies rather than gills.

The fruiting bodies of Laetiporus are typically large and shelf-like, often growing in overlapping clusters. The color can vary from bright yellow to deep orange, and the texture is generally firm and fleshy when young, becoming tougher with age. These fungi are saprobic, decaying wood, and are considered parasitic on living trees, though they typically colonize trees that are already stressed or damaged. They are known to break down lignin and cellulose, contributing to the decomposition of dead wood.

Several species within the Laetiporus genus are edible and are considered a delicacy by many foragers. However, proper identification is crucial, as some look-alike species can be toxic. Consumption is generally recommended only for younger, fresher specimens, as older ones can become tough and have a strong flavor. It is also important to harvest them from healthy-looking trees, as they can absorb toxins from their environment. Different species may have slightly different culinary qualities and growing preferences.
