Boletus luridus var.

caucasicus Singer Boletus caucasicus Singer (1966) Boletus luridus subsp.

caucasicus (Singer ex Alessio) Hlavácek Suillellus caucasicus is a species of bolete fungus in the family Boletaceae.

It was first described as a variety of Boletus luridus in 1947 by Rolf Singer,[1] then as an independent species by Singer in 1966.

The name change in the latter publication was invalid, so Carlo Luciano Alessio published the new combination validly in 1985.
