Observation 172664: Retiboletus griseus var. fuscus
When: 2014-08-04
No herbarium specimen

Notes: Found at trailside in mixed hardwoods and mountain laurel. Dominant tree is chestnut oak, Quercus montana. No conifers in the area. The cap is “hard”, dimpled over the disc. Pileipellis color is an odd deep olive brown with a purplish tinge. There is a well-defined sterile margin. The immature, white pore surface readily bruises brown. After a day of failure to produce a spore print, the pores pinkened. Initially the flesh was white, slowly yellowing after exposure. A day later, the flesh was pinkish when cut and gradually became more so. Worm tunnels present and copperish. Reticulation extends half-way down stipe. The stipe has a chrome yellow foot. No distinct smell. Taste mild. NH4OH on the cap=pale orange, flesh negative. KOH on the cap=dark amber, orange on the context. FeSO4 on the cap and flesh are slowly blue green.
