Observation 139124: Boletus L.
When: 2013-07-04
No herbarium specimen

Notes: Growing gregariously under oaks.

The mature pore surface is greenish-yellow and the spore print is greenish-brown, so it’s in the genus Boletus. This is not B. variipes or B. atkinsonii, judging from the gross morphology and macrochemical tests.

Macrochemical tests: both KOH and NH4OH on cap turn dark brown; both resolve into orange after a few minutes. NH4OH vapors produce a wide purple-blue “aura” around the liquid droplet on cap. Both KOH and NH4OH are negative on the flesh.
