Observation 136669: Buchwaldoboletus hemichrysus (Berk. & M.A. Curtis) Pilát
When: 2013-06-09

Notes: This specimen was found in the Turkey Creek Unit.
Spores were olive brown and in the range of 6.3-7.8 X 2.9-3.3 microns.

While MO continues to list Buchwaldoboletus sphaerocephalus as a preferred synonym for Buchwaldoboletus hemichrysus, I have to agree with Beatriz Ortiiz-Santana and Ernst Both, who quote Watling in their 2011 paper “A Preliminary Survey of the Genus Buchwaldoboletus” (Bulletin of the Buffalo Society of Natural Sciences, Vol. 40)…“The two fungi are not the same”.
The species that I have found several times in Texas has a distinctive bright yellow powdery cap and when young, a distinctive reddish-brown pore surface.
Also, I believe the spores are somewhat smaller for the B. hemichrysus.
