Remarks
Beetles always make the entrances through the top of the sporocarp, whether they are living in Ganoderma applanatum in the northern part of their range or in G. lucidum in the southern part... Those living in the north are generally of a lighter color than those in the south, which tend to be black rather than cocoa brown. (Comment here)
