This red-capped bolete came up in the shady flowerbed behind my patio. There were another three or so smaller ones within the same general area. When I tugged this largest one up to get photos, it came attached to a hickory nut shell. Aside from hickories, there is also a shingle oak (Quercus imbricaria) nearby.
This individual has a cap 4.8 cm across. The stipe was 7 cm long, and adding on the cap, the mushroom was 9 cm tall. The stipe immediately stained blue when I cut off the cap to try setting up a spore print.
Younger individuals had very deep red caps, but this one had gotten paler and browner as it grew. The pores were yellow with some hints of blue staining in damaged areas. You can see a couple of holes that had little brown fungus beetles nibbling away (before I disturbed them).

This little (3 mm long), glossy brown fungus beetle was cuddled down in a hole under the cap of a bolete mushroom that I was trying to photograph. I disturbed it and it ran off, but I managed to get a few photos before it disappeared.
