Polymeridium albidovarians is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae.[1] The lichen was first discovered in Indonesia on the island of Java, specifically at the Kawi-complex, Tjemarakandang, at an altitude of 2,700 m (8,900 ft). This species closely resembles Polymeridium albidum, but is differentiated by its UV+ (yellow) thallus and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. The yellowish-white, [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] thallus features spherical, [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], solitary ascomata measuring 0.2–0.4 mm in diameter, with an apical ostiole. The hamathecium is inspersed with oil droplets, and the [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] number eight per ascus, contain three septa, and measure 20–23 by 6–8 μm without ornamentation. The lichen's chemistry is characterized by the presence of lichexanthone.[2]
