Corner described and illustrated this bolete. Cap has flattened felty patches that may or may not develop into squamules (erect, suberect or flattened). This are pale colored with a hint of pink (pinkish buff). The pileus flesh is yellow and quickly blue. This contrasts with a whitish stipe that stains brownish pink (rufescent) or a dirty orange on the surface AND in the flesh. This is completely different from B. emodensis (Old World) and B. ananas (New World).
