Butyriboletus subappendiculatus

Butyriboletus subappendiculatus is a pored mushroom in the family Boletaceae. It was originally described as a species of Boletus in 1979 before being reclassified in the genus Butyriboletus in 2014. The fungus produces medium-sized fruiting bodies with brownish-orange to buff-coloured caps up to 8 cm across, lemon-yellow tubes and pores that do not bruise blue when damaged, and yellowish stipes covered with a fine network pattern. It fruits in upper-montane coniferous or mixed forests across Europe and into Turkey, primarily under Norway spruce or silver fir on neutral to calcareous soils at elevations of 1,200–1,700 metres. ...read more on Wikipedia.
