Rubroboletus sinicus is a bolete fungus in the family Boletaceae. It is found in China. The species was first described by Wei Fan Chiu as Boletus sinicus in 1948, [2] and transferred to the genus Tylopilus in 1979 by Fanglan Tai. [3] In 2014, the genus Rubroboletus was created to accommodate this and allied species. [4]

The fruit bodies of R. sinicus` have a brown, pulvinate (cushion-shaped) cap measuring 9–11 cm (3.5–4.3 in) in diameter that is covered with fibrous scales. The tubes on the cap underside are up to 4 mm (0.16 in) long, and stain blue when cut or injured. The pores are red and small, up to 0.5 mm across. The flesh is initially white to yellowish, but stains blue with injury. Spores are ellipsoid and measure 7.5–11 by 4.5–5.5 μm. The type collection was obtained from a market in Kunming in July, 1938.

Rubroboletus sinicus (along with Butyriboletus roseoflavus , Lanmaoa asiatica , and Sutorius magnificus ) has been suggested as a possible identification of the blue staining bolete mushrooms found in Yunnan province known as 见手青 (jianshouqing) or "Xiao Ren Ren mushrooms", which have been reported to produce psychedelic effects especially when undercooked, and have been theorised to contain psilocin or psilocybin. However the presence of these alkaloids has not been confirmed and remains inconclusive. [5] [6]
