Description:
Original observation #74058 (Mushroom Observer)
Occurrence Remarks:
An adorable caespitose family of a Tylopilus species growing in the shade of a small pure stand of oak trees made me smile on a rainy and cool afternoon in the Poconos. I left the happy familiy untouched and instead collected what appeared to be conjoined fungal twins fused to form a single peculiarly shaped basidiocarp that I christened "fat boy" [Tylopilus is a masculine name after all]. :-) This is a mild tasting larva-free bolete with a very pleasant sweet fungal odor. The stipe is brownish on the bottom half, whitish at the top with a narrow band of prominent white reticulation at the apex. The context is whitish, staining pinkish-brown almost immediately upon oxidation (the color intensity reached its peak several minutes following exposure to air). The dark brown pileus, lacking purplish tones and margin chamfering, together with the context staining pale yellow with application of KOH (aq) seem to eliminate T. badiceps and, to a lesser extent, T. indecisus, though now I am beginning to distrust the KOH-on-context test in light of the personal experience with species of this type as well as obs. #73673). I find the poorly matching results of macrochemical tests on the pileipellis to be less reliable because they were conducted after a substantial delay and excessive handling.
