🔬 Morphology
Cap
Amyloporia sinuosa
The fruiting body is spread out, flat, up to 20 cm across. Color changes: white when young, yellowing over time, light brown as it dries.
Antrodia albida
Fruiting body annual, spread out. Caps up to 8 cm long, 2–3 cm wide. Color: whitish at first, turning pale yellow with time. Often grows in overlapping, tile-like groups or long rows.
Hymenophore
Amyloporia sinuosa
Tubular pore surface. Tubes short, 0.5–2.5 mm. Spore print whitish. Spores cylindrical, colorless, 4–5.5 × 0.75–1.5 µm.
Antrodia albida
Tubular hymenophore. Spore print white. Spores cylindrical, colorless, 8–14 × 3.5–6 µm.
Stem
Amyloporia sinuosa
There is no stem. The body is spread out and attached to the substrate over its whole surface.
Antrodia albida
No stem. The fruiting body is attached to the substrate by its whole base.

Amyloporia sinuosa
flesh white, yellowing over time. The mycelium penetrates deep into the wood along cracks — hence “sinuous” (winding) in the name.
Antrodia albida
flesh thin, leathery. Whitish when young, yellowing with age.
