Pseudoboletus parasiticus parasitizing Scleroderma citrinum. Photographed last night at Mycofest in Pennsylvania with a Convoy C8 365 nm UV flashlight and Acebeam PT40 white LED flashlight. I noticed this bolete was fluorescent by running the UV light over the specimen table at night.
Retiboletus ornatipes with both 365 nm ultraviolet light and white light.
