are all the way up, but harder to see on the young ones in these pictures. fewer spores have yet fallen on them to make them more visible.

interesting bolete.

it almost looks like the reticulations are concentrated at the base…hard to see much at the stipe apex.

Also recently found near Balsam Grove, NC under oaks.

Great pictures. I found three of these beauties under oaks in grass near Balsam Grove, NC and your pictures helped me identify them.
