Fissurina khasiana is a species of corticolous (bark-dwelling) script lichen in the family Graphidaceae.

[1] It is found in India, specifically in the evergreen forests of Upper Shillong in the Khasi Hills; its species name is derived from the region where it was first collected.

[2] The thallus of Fissurina khasiana is greyish-green in colour, with a smooth and cracked surface that appears pruinose.

[2] Chemical spot tests reveal that the thallus of Fissurina khasiana has K+ (yellow-red), C−, KC−, P+ (orange), and UV− reactions.

However, Fissurina khasiana is distinct from other species in this group due to the presence of both stictic and constictic acids in its thallus.
