Sulfur-Colored Chicken of the Woods (Sulfur Shelf; Chicken Mushroom)
Layered, fan-shaped, fleshy; orange-red to orange-yellow on top; sulfur yellow below. Grows in overlapping clusters on dead or dying deciduous trees, stumps, buried roots, or living trees. May–November. Each cap flat, fan-shaped, or semicircular; orange-red to orange-yellow when fresh, turning lighter with age; texture fleshy. Pores angular; bright sulfur yellow. Stalk not present. Spore print white. Spores magnified are elliptical to round.
Lookalikes: Pale chicken of the woods (Laetiporus cincinnatus) is white on the underside. No other Missouri mushrooms have the color, shape, and growing habit of the two “chicks” (L. sulphureus and L. cincinnatus).
