The Chicken Mushroom Announces Its Presence Loudly

Today, Teresa Marronne and Walt Sturgeon share with us some fascinating facts about the colorful Chicken Mushroom.

Laetiporus sulphureusUnlike other edible mushrooms that seem to use natural camouflage to hide from the eager forager, the Chicken Mushroom (Laetiporus) announces its presence loudly. Its bright colors, large size, and frequently elevated location make it easy to spot from a fair distance.

The mushrooms are found in association with live, dead, or dying trees. The appearance of Chicken Mushrooms on a living tree is a signal that the tree has been attacked by the mushroom’s parasitic mycelium (thread-like fungal roots), which can sometimes be seen as whitish fibers in cracks in the wood. The fungus causes heart rot of the host tree.

Three different species are found in our area. All grow as a grouping of thick, stemless, fan-shaped caps; individual caps may be up to 12 inches wide but are generally smaller. Caps are some shade of orange to yellow-orange, with a fair amount of variation among different groupings of the same species. They are smooth to wrinkled and may be leathery but are not hairy. Edges may be rounded or scalloped and range from flat to wavy. The underside of each cap is covered with tiny pores.

  • Laetiporus sulphureus (also called Sulphur Shelf and Polyporus sulphureus) is the most well-known Chicken Mushroom. It grows directly on deciduous wood, favoring oaks; it often grows on standing trees but is also found on stumps and downed wood. The caps are typically arranged in tight, overlapping, shelf-like layers but may occasionally grow as a rosette. The pore surface is bright yellow; cap edges are often yellow.
  • The White-Pored Chicken Mushroom (Laetiporus cincinnatus; also listed as P. cincinnatus) has a white to buff pore surface and usually grows as a rosette rather than as a cluster of overlapping shelves. It is most often found on the ground or on top of stumps, over buried roots of oak, and, occasionally, on the roots of other deciduous trees. It has softer, more muted colors than Laetiporus sulphureus, and the cap edges are often white.
  • Laetiporus huroniensis has an appearance that is identical to L. sulphureus, but it grows on hemlock and pine logs and stumps. It is usually found in mature conifer forests.

Laetiporus cincinnatusChicken Mushrooms also go by the name of  Chicken of the Woods and Sulfur Shelf. They are in season late spring through fall.
