Recognized by sight: Wetmore mentions that Thompson says that “this species has a K+ yellow medulla”, indicating that he was using P. callosa sensu Thompson (and that he failed to get this K+y reaction), which Esslinger indicates is referrable to P. tribacia (and which truly does have a K- medulla).
