Ganoderma species

Description:

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.

Habitat:

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.
