Recognized by sight: another one of those darned orange pored Xerocomus. Note red color in cracks on cap. Also cap context turned orange (originally yellow) with age. Why not the pore mouths, too? Blues rapidly everywhere. Spore print pending. Mendocinensis, the Xerocomus “Flavor of the Month” supposedly has giant spores. Will this orange pored bolete have them, too? Stay tuned…

Recognized by sight: rapidly bluing pores, yellow mycelia.

These spores are truncated. Haven’t studied sufficiently the question of X. mendocinensis, but X. truncatus is probably not a bad name to use at that stage, particularly when supported by the nice spore shot.

Are those…

Does that look like truncate spores there? Ok, then truncate spores. What was it, you scratched it and said it to be B. truncatus, and I didn’t think the rapid bluing was all that important. But there you go I guess…

included in the obsie. also reddening pore surface.
