Taxonomy

This fungus is a member of the G. applanatum group.

Description

It is a perennial, sessile, concentrically zonate polypore that is 5–65 cm (2.0–25.6 in) in length that can be a number of dull tones ranging from brown to gray.[2] It parasitizes both conifers and hardwoods, with a preference for the latter. Its pore surface is white but easily turns shades of brown upon damage. According to Michael Kuo, it has larger spores than G. applanatum, measuring 9–12 by 7–9 μm.
