as seen under the species name “Boletus spadiceus”, “Pore surface… often but not always staining blue or blue-green when bruised.” B. ferrugineus is the currently listed name for the former B. spadiceus (Index Fungorum).

Just to be certain there’s no confusion… The species Tylopilus ferrugineus does stain brown. This species is unrelated to the mushrooms posted here.

Ferrugineus is bruising brown not greenish blue.

My opinio.

To my experience these is definitely not ferrugineus.
