Fissurina simplex is a species of corticolous (bark-dwelling), crustose lichen in the family Graphidaceae.[1] Described in 2012 from specimens collected in Kerala's Silent Valley National Park, this lichen forms brown, glossy crusts on tree bark in humid evergreen and deciduous forests of the Western Ghats. It is distinguished by its variable ascospore number (one to four per reproductive cell rather than the typical eight), large spores divided into brick-like compartments, and the presence of stictic acid compounds in its tissues.
Fissurina simplex is a member of the family Graphidaceae that was formally described as a new species in 2012 by Bharati Sharma, Pradnya Khadilkar and Urmila Makhija. The holotype was collected on 31 December 1981 in Silent Valley, Kerala, India. The authors noted that the species is readily distinguished from other Fissurina taxa by its combination of stictic-series acids, swollen thalline margins, 1–4-spored asci and comparatively large muriform spores.[2]
