Can anybody here help me to identify precisely if that fungus is Ganoderma curtisii, G. lucidum or G. tsuage...? It grows on old spruce stump and this place has produced 1-2 items per season. Older versions were growing into orange-red huge specimens. I add two photos from late winter, where we got these two items.
cut down spruce forest, growing on spruce stump, nearby having different other funguses, one similar 150 meters away, growing close to walking path in the grass.
