Polymeridium neuwirthii is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae.[1] Found in Venezuela, it was formally described as a new species in 2014 by Dutch lichenologist André Aptroot. This [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] lichen has a pinkish-grey thallus that does not fluoresce under ultraviolet light. P. neuwirthii is similar to Polymeridium quinqueseptatum but can be differentiated by its [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] with large oil droplets and consistently 7-septate, rough [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. The ascomata are 0.4–0.6 mm in diameter, with a spherical [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] that is [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] and solitary. The ostiole is apical, and the [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] contains large oil droplets. There are eight ascospores per ascus, which are iodine-negative, 7-septate, and measure 30–33 by 9–10 μm. The ascospore wall is roughly ornamented. No chemical substances have been detected in this lichen. The type specimen was collected in Puerto Ayacucho, Venezuela, on a twig of a shrub. The species is named in honour of the collector of the type and only specimen, Gerhard Neuwirth.[2]
