Cap 100-300 mm broad x 80-140 mm thick, fan-shaped, in overlapping clusters, margin wavy, sulcate, surface dry, tomentose to velvety, zonate, sulfur yellow to orange or orangish red with white margin, becoming dingy brownish orange in age. Spore-bearing surface poroid, sulfur yellow. Tubes 2-4 mm long, yellow. Pores 3-4 per mm. Stem absent. Spore deposit white. Edibility: Although Laetiporus sulphureus is known as the Chicken-of-the Woods or sulfur shelves and considered a premium edible species, there are reports of gastric upsets resulting from eating fruiting bodies growing on Eucalyptus. Laetiporus is also found on koa and ohi'a in mesic montane habitats, and collections from these sites make excellent eating.
