Species of lichen
Fissurina submonospora is a species of corticolous (bark-dwelling), crustose 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 Upper Kodayar (Tamil Nadu), where it was found growing in a humid evergreen forest. This lichen has a brownish grey to dark brown, cracked and uneven thallus, delimited by a black hypothalloid region at its periphery. Its ascomata are short, simple to branched, and immersed, with a structure of dumastii-type, while the disc is slit-like. The ascospores are hyaline, muriform, with 10–15 transverse and 4–5 longitudinal septa, and typically measure 70–100 by 20–50 μm, with a 2.5–10 μm-thick halo.[2]
