Recognized by sight: Found on what appears to be a stump of a Bigleaf maple (Acer macrophylla) dead less than 1 year since bark still present on stump. Conks growing out of bark, and not apparently pealing the bark away from the stump. Fruiting body grayish brown to white and top of cap/shelf; pure white underneath. I couldn’t get close enough to the fungus to see if it was soft, and took the pictures from across a ditch next to a well-traveled highway during a rain shower. Fungus looks stout, probably 4-8 inches thick from top to bottom, and pretty wide: about 20 inches across that I could see. Seemed to form a near solid circle around a rather large stump of perhaps 28 inches in diameter. Unlike most Ganodermas I have seen, including G. applanatum which can reach this size, but tends to be thinner fleshed. Bottom line: I don’t know this one!
Used references: Tried to use the key in Aurora’s Mushrooms Demystified, but this specimen doesn’t appear to follow any of the key characteristics in the key that I could tell visually. Unless it is an unusually large and thick G. applanatum (Artist’s conk) and it doesn’t have the dramatic fan-shape of that species in my experience, then I’m not sure what this large, thick, dense and hard-looking polypore is.
