Austrographa
Austrographa is a genus of lichen-forming fungi in the family Roccellaceae. It has three species. The genus was circumscribed in 2013 by lichenologists Laurens Sparrius, John Elix, and Alan Archer, with Austrographa kurriminensis assigned as the type species. The genus had been published invalidly on two separate occasions. All three species in the genus were found in a mangrove stand in Queensland, Australia. The genus was discovered in Australia, and the name Austrographa reflects this. Description
Austrographa is a genus of crustose, corticolous (bark-dwelling) lichens, with a smooth, water-repellent thallus densely filled with fine crystals and a cortical gel. The thallus is not  and lacks roccellinic acid. The  of the lichen is from Trentpohlia, a genus of green algae. The ascomata are rounded to , usually aggregated in linear or rounded .
