Observation 25982: Aureoboletus auriporus (Peck) Pouzar
When: 2009-09-21
No herbarium specimen

Notes: This looks like a pretty good match for the species. The cap was a little viscid and the pores were certainly bright yellow, and there was some white mycelium at the base.
The spores were olive brown and ave. 12.5 X 5.0 microns. Also, the cap “skin” or pileipellis easily peeled off which is noted in the Bessette description.
5-29-2012: added spore micro photo. Spores ~ 11.7-15.2 X 4.9-6.1 microns.

[admin – Sat Aug 14 01:58:33 +0000 2010]: Changed location name from ‘Big Thicket, Tyler Co. Texas’ to ‘Big Thicket, Tyler Co., Texas, USA

Very mixed woods

in this area of the Big Thicket park system. I have trouble identifying trees in SE Texas because I am not a resident of the area and also from a practical matter the woods are often so mixed and dense that it becomes impossible to say which tree might be associated with one particular mushroom. Usually, one has a choice of perhaps 3 or 4 tree species within a 25 foot radius. Certainly oaks were in the vicinity of these specimens.

an oak leaf visible in the second photo. So there must be both pine and oak around.

I expected to see more red streaks on the stipe. I see a lot of pine needles in your pics — did you find these under oak though?
