Caloboletus panniformis is a bolete fungus native to Honshu island in Japan, where it grows under conifers in subalpine regions.

Until 2014, it was known as Boletus panniformis.

Recent changes[1][2] in the phylogenetic framework of the family Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus.

[2][3] It was first described scientifically in 2013 by Japanese botanist Haruki Takahashi and colleagues.
