When: 2017-06-14

Collection location: Lake Livingston State Park, Polk Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

Notes:
Growing at the base of an old tree in mixed woods.
Caps up to 4.6 cm across surface and tacky.
Spore print reddish brown.
Spores ~ 9.9-12.5 X 4.8-6.0 microns.
They appeared smooth.
Unfortunately I do not have vouchers for these.
The tacky caps and smooth appearing spores cast doubt on my ID.
They do look similar to the photo in the latest Bessette et al Bolete book.
Could use some help.

…not as rare as I thought it was. There are almost two dozen observations on MO. Seems like the distribution range is limited to the southern/southeastern states, but there is also a large number of sightings from OH west to MO. Nothing north of NC along the East Coast.

Yes…and the color of the pores

in Kuo’s photo look identical.
I also see that in the older Snell & Dick Bolete book, they use the term “ferruginous in deposit” to describe the spores.
Wonder how the “olive brown” thing got started(?).

…the color of the spore print as rusty brown. Too bad you could not save these, Ron.

I initially assumed they were B. curtisii

but the spores are not olive brown and the pore color is wrong(due to the reddish brown spore development). (?)
