Xerocomus mcrobbii McNabb 1968
Xerocomus mcrobbii has the general appearance of a Boletellus, but may be distinguished from members of that genus by the short smooth spores and hymenophoral trama of the Phylloporus subtype. Although the ammonia reaction of fresh pilei is not known, the short spores (Q=2) indicate that Xerocomus mcrobbii most probably belongs in sect. Pseudogyrodontes. The fact that it has been found only under Nothofagus in two widely separated localities suggests that it is a mycorrhizal species.
Xerocomus mcrobbii may be recognised by the olive pileus, which becomes fibrillose-scaly at maturity, yellow tubes and deep red pores, and short spores.
