Fissurina immersa is a species of corticolous (bark-dwelling) script lichen in the family Graphidaceae.[1] Found in India, it was formally described as a new species in 2012 by Bharati Sharma, Pradnya Khadilkar, and Urmila Makhija. The type specimen was collected from Mudigere (Karnataka). The lichen has a brown, uneven, finely cracked, and glossy thallus that is delimited by a black hypothalloidal region at the periphery. The lirelline ascomata are the same colour as the thallus and are 0.2–1.5 mm long, straight to curved, terminally acute, and have a dumastii-type structure. The ascospores are hyaline, somewhat muriform, and measure 12–13 by 3–5 μm, with 3–4 transverse and 1 vertical septa. It contains norstictic acid in its thallus.[2]
