I’ve been waiting for this type to show up in the usual corner of my property, grassy wood border. I’ll harvest tomorrow and see if the the rather distinctive KOH profile for T. rubrobrunneus matches this obs. Looks like the olive stains on the stipe may be developing.

Bolete Bill at NEMF. Had another of these with me to show him. He says that insect infestation is common with T. rubrobrunneus.
The insects seem to dislike the bitter Tylopilus species. Generally, these types are immaculate inside. Maybe the bugs are kinda hard-up for food right now…? Due to hot and dry conditions from mid June through mid July, the larger types of boletes are just starting up around here, so we’re about a month behind schedule.
Leaving home for NEMF in just a few minutes. I should have saved some of the material from this collection. The combination of infestation and puzzling KOH reaction make this an interesting find. If the past is any indication, there will be more of these to examine. One patch, about 9 square yards, typically produces these mushrooms up until mid October.
Natural stains on stipe dark brown. Rubbing stipe caused a very slight olivaceus stain. Pores bruising as seen in photo.
KOH application quite a bit different than B/R/B report for T. rubrobrunneus. Only color change was on the cap surface, which went from the deep purple as seen in the photo to a vivid mustard green where the KOH was applied. Cap context negative. Stipe context… non-existent… an insect megalotropolis! And it looked so fresh from the outside.
