Observation 26474: Boletus

When: 2009-09-23

Collection location: Big Thicket, Polk Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

These don’t quite fit into any slot yet although they seem close to the Boletus illudens-Boletus spadiceus group.
The caps were up to 5.6cm across and the color was a mix of light brown, yellow and pink. They seemed to be finely rimose or cracked which throws into doubt the matches for the above species. The stems did have a rather coarse reticulation especially topside. There was some minor bluing of the light yellow cap flesh near the stem connection and the tubes. The taste and odor were not distinctive.
The spores were olive brown and fusiform to subfusiform, approx. 13 X 5 microns.

looks good to me also. I’m hesitant naming many of these boletes that I rarely see. For some reason the site won’t let me propose the new name or destroy the old one?!?

or illudens seems to me to be on the money Ron. The cap of spadiceus is often finely rimose in age and the dull pink tones that show through the cracks are also typical of the spadiceus that I find in CT. I found many B. spadiceus at the Lincoff Mid Atlantic foray last month and they match up well with your mushrooms.
