Carbacanthographis indica is a species of bark-dwelling crustose lichen in the family Graphidaceae.[1] It occurs in Meghalaya, India.
The species was described as new to science in 2011 by Bharati Sharma and Pradnya Khadilkar, based on material housed in the Ajrekar Mycological Herbarium (AMH). Their Latin diagnosis states that it resembles C. marcescens but differs in having spores with transversely arranged septa (trans-septate). The holotype was collected in the Garo Hills of Meghalaya (India), from a Lagerstroemia forest on 5 November 1977. In the original account, C. indica is defined by a laterally carbonized (blackened) exciple, trans-septate ascospores, and the presence of salazinic acid. In their comparisons, the authors note that C. marcescens (the other species reported with salazinic acid and a laterally carbonized exciple) differs in having smaller, muriform (multi-chambered) spores. They also distinguish C. indica from morphologically similar species such as C. induta and C. iriomotensis by chemistry, and discuss Graphis garoana as a related Indian species that fits Carbacanthographis but has much longer lirellae and contains norstictic acid in addition to salazinic acid.[2]
