Fulvophyton macrosporum

Species of lichen

Fulvophyton macrosporum is a species of corticolous (bark-dwelling), crustose lichen in the family Roccellographaceae. Found in the Seychelles, it was formally described as a new species in 2017 by lichenologists Damien Ertz and Paul Diederich. Its differentiation from the morphologically similar Sclerophyton madagascariense primarily hinges on its 10–14 septate (partitioned) ascospores and the existence of psoromic acid, while S. madagascariense typically contains 8–10-septate ascospores and features stictic acid. Fulvophyton macrosporum was first identified in Seychelles, in the Praslin National Park, situated southeast of Vallée de Mai. The species was discovered growing on trees between altitudes of 250–360 m (820–1,180 ft). Its species epithet macrosporum alludes to the relatively large ascospores that characterise the species.
