Graphis desquamescens is a species of script lichen in the family Graphidaceae.^[2] It has a broad distribution and can be found in various countries including Brazil, Dominica,^[3] the United States,^[4] Mexico, and Japan. It also occurs in different parts of Australia such as Queensland, New South Wales, Victoria, and Tasmania.^[3] It was reported as new to Myanmar in 2020.^[5]

There has been little agreement in the literature as to the length of the ascospores in this species; they have been given various ranges extending from 18 μm to as high as 50 μm; the ascospores of the lectotype specimen have a reported range of 25–35 μm.^[4]

The novel pigment named graphisquinone was isolated from cultures of the spore-derived mycobionts of this lichen.^[6]
