Tylopilus rhoadsiae, commonly known as the pale bitter bolete, is a bolete fungus in the family Boletaceae native to the eastern United States.
Taxonomy
The species was
William Alphonso Murrill,[2] and later transferred to the genus Tylopilus by Murrill in 1944.[3] In 1942, Wally Snell moved the species to Leucogyroporus, a genus he created to contain several species from Florida originally placed by Singer in Gyroporus;[4] Leucogyroporus has since been subsumed into Tylopilus.[5]
The mushroom is commonly known as the "pale bitter bolete".[6]
Description
buff, greyish buff, or pinkish shades mixed in. The flesh is white, lacks any distinct odor, and has a bitter taste that renders the mushroom inedible. The flesh does not discolor when it is cut or otherwise injured. On the cap underside, the pore surface are initially white, but turn pale pink as the spores mature. The pores are irregularly shaped, and number about one or two per millimetre, while the tubes are 0.9–1.6 cm (0.4–0.6 in). The stipe measures 5–10 cm (2.0–3.9 in) long by 1.6–2.8 cm (0.6–1.1 in) thick, and is roughly equal in width throughout its length, although it can have a pinched base. Its surface is dry, its color whitish (or similar to the cap color), and it has distinct reticulations (a mesh-like pattern) on its upper half.[7]
The
cap cuticle yellow.[7]
Similar species
The widely distributed bolete Tylopilus felleus is similar in appearance to T. rhoadsiae, but has a very bitter taste, and a darker cap. Tylopilus rhodoconius has a cap that is initially brownish-orange before turning dark brown in age, and a white pore surface that stains brown when bruised.[8]
Habitat and distribution
Fruit bodies of Tylopilus rhoadsiae grow scattered or in groups on the ground under
