Tells: Viscid & almost-corrugated cap is a shade of brown (red-, orange-, yellow- or plain). Stem often long & curved. Flesh often stains pinkish red.

Other Information: B. viscidocorrugis & B. longicurvipes were considered two species prior to DNA testing, with the only difference being whether the flesh stained. They’re now considered to be the same species with the staining an in-species variation. The superseded Latin name helps with the ID: ‘viscido’ and ‘corrugis’ being two main tells about the cap.
