Psoroglaena humidosilvae is described as a new lichen species from a wetland forest in South Korea. It differs from other Psoroglaena species in terms of its thallus projections, perithecia size and shape, asci size, and septate ascospores. Molecular analyses using ITS, mtSSU, and LSU sequences support P. humidosilvae as a distinct species in the genus Psoroglaena. A surrogate key is provided for the identification of all 22 Psoroglaena species.
Psoroglaena humidosilvae Lee is described as a new lichen species from a wetland forest in South Korea. The new species is distinct from P. stigonemoides (Orange) Henssen by little projections locally present on the thallus; smaller, paler, and globose perithecia; smaller asci; and smaller ascospores generally 3-septate. Molecular analyses employing internal transcribed spacer (ITS), mitochondrial small subunit (mtSSU), and nuclear large subunit ribosomal RNA (LSU) sequences strongly support P. humidosilvae as a nonidentical species in the genus Psoroglaena. A surrogate key is provided to assist in the identification of all 22 species of Psoroglaena.
