A peculiarity of this fungus lies in its use as a drawing medium for artists.[1] When the fresh white pore surface is rubbed or scratched with a sharp implement, dark brown tissue under the pores is revealed, resulting in visible lines and shading that become permanent once the fungus is dried. This practice is what gives the Ganoderma applanatum it's common name.[2]

This fungus grows as a mycelium within the wood of living and dead trees. It forms fruiting bodies that are 3–30 cm wide × 5–50 cm long × 1–10 cm thick,[3] hard as leather, woody-textured, and inedible.[4] They are white at first but soon turn dark red-brown. Brown spores are released from the pores on the underside of the fruiting body. The spores are highly concentrated, and as many as 4.65 billion spores can be dispersed from a 10-10cm section of the conk within 24 hours.[2] The tubes are 4–12 mm deep and terminate in pores that are round with 4–6 per millimetre.[3] The fruiting bodies are perennial, and may persist for multiple years, increasing in size and forming new layers of pores as they grow. These layers can be distinguished in a cross section, allowing the fruiting body's age to be determined using the same method as tree rings.
