lists T. sordidus as having flesh that stains blue/green, and T. pseudoscaber as having pores that bruise blue green. The stalk base of this specimen (22609) did NOT stain in the cut stalk base. The slight green staining appeared on the part of the stalk where the scruffy scaber like bumps had been rubbed off or eaten by an insect.

The stalk of this mushroom was still lying on my kitchen table this morning. I put a drop of KOH on the flesh and it turned a bit orange.

that turn greenish in the base of the stipe? This certainly indicates Leccinum species I would say.

could be L. albellum. But what threw me off that trail is the lack of olive tones in the spore print. If anything, it’s more on the red side of brown than the green side.
