Rubroboletus
Rubroboletus is a genus of bolete fungi in the family Boletaceae. It was circumscribed by Chinese mycologists in 2014 with Rubroboletus sinicus as the type species. Species are characterized by having a reddish cap surface, yellow tubes on the underside of the cap, and an orange-red to blood-red pore surface. Pinkish to red spots (reticula) are present on the stipe surface, and a bluish color change occurs when the bolete flesh is injured. Rubroboletus mushrooms have an olive-brown spore print, and produce smooth spores. Eight species were included in the original circumscription (seven new combinations and one new species); five were added in 2015, and another in 2017. Several species in this genus are poisonous. Although R. sinicus is sporadically sold in markets in Yunnan, China, it is suspected of being poisonous; further studies are need. Species
