Lee, B.G./ Hur, J.-S. 2021: Two new lecanoroid lichen species from the forested wetlands of South Korea, with a key for Korean Protoparmeliopsis species. - MycoKeys 84: 163-183. [RLL List # 269 / Rec.# 43505]
Abstract: Lecanora parasymmicta Lee & Hur and Protoparmeliopsis crystalliniformis Lee & Hur are described as new lichen species to science from the forested wetlands in southern South Korea. Molecular analyses employing internal transcribed spacer (ITS) and mitochondrial small subunit (mtSSU) sequences strongly support the two lecanoroid species to be distinct in their genera. Lecanora parasymmicta is included in the Lecanora symmicta group. It is morphologically distinguished from Lecanora symmicta (Ach.) Ach., its most similar species, by areolate-rimose thallus, blackish hypothallus, larger apothecia, absence of thalline excipulum from the beginning, narrower paraphyses, larger ascospores, smaller pycnoconidia, and the presence of placodiolic acid. The second new species Protoparmeliopsis crystalliniformis is included in a clade with Protoparmeliopsis bipruinosa (Fink) S.Y. Kondr. and P. nashii (B.D. Ryan) S.Y. Kondr., differs from Protoparmeliopsis ertzii Bungartz & Elix, its most morphologically similar species, by whitish thallus, flat to concave and paler disc, longer ascospores, thallus K+ yellow reaction, presence of atranorin and rhizocarpic acid, and the substrate preference to sandstone or basalt. A key is provided to assist in the identification of Protoparmeliopsis species in Korea.
