Collection location: Big Thicket National Preserve, Tyler Co., Texas, USA [Click for map]
These were a little larger than the standard Boletus campestris or Boletus fraternus. The caps were from 6.0 to 7.6 cm across and the stems up to 8 cm.
The pores stained green-blue rapidly as well as the stem flesh and the cap flesh a little slower. I would say the initial pore color was not bright yellow, more creamy. Also the subfusiform spores seemed larger than that reported for the above species. The were more like 14.2-16.5 X 5.0-6.1 microns.
Maybe it’s true that everything is bigger in Texas!
