Observation 103026: Retiboletus Manfr. Binder & Bresinsky
When: 2012-07-07
No herbarium specimen

Notes: Hoping desperately to identify a Mexican mushroom with an American field guide, this species came up.

Features: Cap is 4.2 cm broad, with varying shades of brown, somewhat paler at margin, not exactly smooth but almost so, no discoloration upon handling or slicing. Tubes appear whitish to faint yellowish to solid yellow, do not discolor. Stalk 4.5 cm tall, distinctly reticulate, colored brownish at base and becoming white near apex. Again, no color change upon handling. Occurs solitary; unfortunately, this is the only one I found in the conifer-rich area. Smell is non-distinct and merely mushroomy. No maggots were present within any part of the bolete.

Base of stalk.
The best spore print I could manage; it may be that, due to the size, this bolete is fairly young and not producing as many spores as it could at maturity.
Cross-section of tubes and flesh.
Piece of the cap one day after it had been picked; no apparent discoloration, fading, or darkening.
