Taxonomy
[edit]Originally described by Jean-Baptiste Barla as Boletus sphaerocephalus in 1859, it was given its current name by Roy Watling & Tai Hui Li in 2004. [1]
Description
[edit]The cap is convex, glabrous, silky and tomentose, viscid when wet. Its color is yellow to yellow-fulvus.[2] It reaches 5–15 centimetres (2–6 in) wide.[3] The pores are small, tubes short, and adnate ventricose. The context is yellow, bluing when bruised.[3] The stipe is fleshy, ventricose, and there is a yellow mycelium at the stipe base;[2] it reaches 3–12 cm (1+1⁄4–4+3⁄4 in) tall and 2–5 cm (3⁄4–2 in) wide.[3]
Spores are ovoid, pale ochraceous and measure 5.5–7.2 by 3.3–4.5 μm.[2] The spore print is brown.[3]
