Ampliotrema sorediatum, a corticolous lichen, is a species in the family Graphidaceae.[1] It was discovered in the tropical lowland rainforest of Peru. The species epithet sorediatum refers to the unusual sorediate thallus, which distinguishes this species from its closest relative, Ampliotrema lepadinoides. The lichen was described as a new species in 2008 by lichenologists Eimy Rivas Plata and Robert Lücking.

Description

The grey-olive thallus of A. sorediatum is up to Шаблон:Convert in diameter, 50–100 μm thick, and continuously sorediate, with soralia measuring 0.1 mm in diameter. The Шаблон:Lichengloss partner Trentepohlia, characterized by angular-rounded to elongate cells, is abundantly present, and the Шаблон:Lichengloss and medulla are incrusted with clusters of calcium oxalate crystals. The Шаблон:Lichengloss of A. sorediatum are rounded, prominent to sessile, and partially covered by a 0.2–0.3 mm-wide pore that is yellow and Шаблон:Lichengloss. The hymenium is strongly and densely Шаблон:Lichengloss, with paraphyses that are mostly unbranched, and asci that are Шаблон:Lichengloss in shape. The protocetraric and virensic acids found in the exposed medulla and apothecial Шаблон:Lichengloss, respectively, give a P+ (orange-red) and K+ (red) reaction with standard chemical spot tests.[2]

The species is found in secondary forests on tree bark in Madre de Dios, Peru. Ampliotrema sorediatum is anatomically similar to Ampliotrema dactylizum but is the first sorediate species in the genus.[2]
