Sorry, I didn’t notice the cross-sectional photo. Mushrooms in the A. mellea have flesh that does sometimes stain brownish or reddish-brown; but I haven’t seen this happen as uniformly as seen in the photo. Usually, the reddish-brown staining occurs around insect tunnels in stalk flesh, or in the flesh of older specimens. The cross-sectional cut also appears to show the tough/fibrous outer coating and the more cottony “stuffing” which are characteristics of Armillaria mellea type mushrooms. Dave in NE PA

need to cut stipe (stem) in half to show the brilliant red coloration, which would be quite different from any Armillaria I’ve seen before.
