Phoebus is a fungal genus of previously uncertain familial placement in the order Arthoniales,[1] now placed in the family Lecanographaceae thanks to molecular analyses.

[2] It contains only one species, Phoebus hydrophobius, found in the Ozarks of the central United States, and described as new to science in 2007.

[3] The genus name of Phoebus is named after the mythical Greco-Roman god Phoebus (also known as Apollo) of the sun as the fungus was thought to look like the orange 'sun bursts' on rocks.

[4] The genus was circumscribed by Richard C. Harris and Douglas Ladd in Opuscula Philolichenum vol.4 on page 64 in 2007.
