Fissurina indica

Species of lichen

Fissurina indica is a species of corticolous (bark-dwelling) script lichen in the family Graphidaceae. 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 Wynad forest (Kerala). The thallus of this lichen is greenish and glossy, with a cracked and verrucose texture, and is delimited by a black hypothalloidal region at its periphery. The small ascomata are present all over the thallus and have acute ends, a dumastii-type structure, and are the same colour as the thallus. The ascospores are hyaline, muriform, multilocular, and measure 32–42 by 12–20 μm with an indistinct halo. No lichen products were detected in collected specimens.
