Tylopilus rhoadsiae
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 described in 1940 as Gyroporus badiceps by William [Alphonso Murrill], and later transferred to the genus Tylopilus by Murrill in 1944. 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; Leucogyroporus has since been subsumed into Tylopilus.The mushroom is commonly known as the "pale bitter bolete".
Description
have caps that are convex to flattened, measuring in diameter. They are dry, smooth to slightly hairy, and sometimes shiny. Its color is whitish, sometimes with 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. The stipe measures long by thick, and is roughly equal in width throughout its length, although it can have a pinched base. Its surface is dry, its color whitish, and it has distinct reticulations on its upper half.The spore print is pinkish to brown-violaceus. Spores are smooth, oblong to elliptical, hyaline to pale yellow, and measure 11–13.5 by 3.5–4.5 μm. A drop of dilute potassium hydroxide or ammonium hydroxide solution will turn the cap cuticle yellow.
