Rubroboletus pulcherrimus
''Rubroboletus pulcherrimus''—known as ''Boletus pulcherrimus'' until 2015—is a species of mushroom in the family Boletaceae. It is a large bolete from Western North America with distinguishing features that include a netted surface on the stem, a red to brown cap and stem color, and red pores that stain blue upon injury. To date it is the only bolete that has been implicated in the death of someone consuming it; a couple developed gastrointestinal symptoms in 1994 after eating this fungus with the husband succumbing. Autopsy revealed infarction of the midgut.
==Taxonomy==
American mycologists Harry D. Thiers and Roy E. Halling were aware of confusion on the west coast of North America over red-pored boletes; two species were traditionally recognised—''Boletus satanas'' and ''Boletus eastwoodiae''. However, they strongly suspected the type specimen of the latter species was in fact the former. In reviewing material they published a new name for the taxon, which Thiers had written about in local guidebooks as ''B. eastwoodiae'', as they felt that name to be invalid. Hence in 1976 they formally described ''Boletus pulcherrimus'',〔 from the Latin ''pulcherrimus'', meaning "very pretty". It was transferred to the genus ''Rubroboletus'' in 2015 along with several other allied reddish colored, blue-staining bolete species such as ''B. eastwoodiae'' and ''B. satanas''.
