Also a bracket fungus on oaks, but bright orange-yellow rather than blood-red. Texture is more crumbly, not rubbery. Does not exude red juice. Much different color at every stage of growth.
Side-by-Side Identification
| Trait | Beefsteak Fungus | Chicken of the Woods |
|---|---|---|
| Cap | 10-25 cm across, 3-6 cm thick. Tongue-shaped, fan-shaped, or roughly semicircular. Upper surface is rough, slightly bumpy, moist to sticky. Color ranges from orange-red when young to dark blood-red or liver-colored when mature. Margin is rounded and thick. | No traditional cap — grows as overlapping shelf-like brackets, 5–60 cm across. Bright orange to salmon on top with a suede-like texture when young. Edges are rounded and wavy, often sulfur yellow. Fades to pale whitish-orange with age and becomes brittle. |
| Gills | No gills. The underside has a layer of densely packed, individual tubes (pores) that are not fused together; they can be separated with a fingernail. This is a unique feature among bracket fungi. Pore surface is yellowish to pinkish, bruising reddish-brown. | No gills. The underside has tiny pores — small round holes that release spores. Pore surface is bright sulfur yellow when fresh, fading to white as it ages. |
| Stem | Usually absent or very short and lateral. The bracket attaches directly to the tree trunk, sometimes with a stubby, off-center stalk. | None. Grows directly from tree trunks, stumps, or buried roots as a sessile bracket fungus. Sometimes a very short stubby attachment point, but never a true stem. |
| Spore print | Pinkish-brown to salmon. | White — though collecting a spore print from a bracket fungus is tricky and rarely necessary for ID. |
| Odor | Mild, slightly sour, faintly fruity. | — |
| Habitat | Parasitic and saprotrophic on living and dead oak (Quercus) and sweet chestnut (Castanea sativa). Typically fruits from wounds, trunk bases, or old branch scars on mature trees. Occasionally found on other hardwoods. Causes a brown cubical rot of the heartwood. | Grows on living and dead hardwood trees — especially oak, but also cherry, beech, willow, and occasionally conifers or eucalyptus. Found on standing trunks, stumps, and fallen logs. It's a parasite and wood decomposer, causing brown rot in the heartwood. |
| Season | Late summer through autumn, typically August through November. Peak season is September to October in most of its range. | Late spring through autumn. Peak season is May–October in temperate regions. Often appears after rain. |
