Observation 164516: Boletus L.

May be Phlebopus marginatus or Boletus Edulis, although I prefer the first ID.
Noticeable blue staining. Several specimens found in close proximity at different stages of maturity. All specimens shallow rooted in open forest floor area and direct sunlight.

Blue staining abundant.

Even on buttons. Boletus edulis does not have blue staining that I am aware of, Ian.

Button tubes appear to be red/orange, which matures to a yellow/orange in the photos. No stipe reticulation, which would seem to rule out Boletus edulis also.

Blue reactions appears to react to even grass blades or leaf litter.

Fascinating and colorful fungi!
