Two new Rinodina lichens from South Korea, with an updated key to the species of Rinodina in the far eastern Asia.

ABSTRACT: Rinodinasalicis Lee & Hur and Rinodinazeorina Lee & Hur are described as new lichen-forming fungi from forested wetlands or a humid forest in South Korea. Rinodinasalicis is distinguishable from Rinodinaexcrescens Vain., the most similar species, by its olive-gray thallus with smaller areoles without having blastidia, contiguous apothecia, non-pruinose discs, paler disc color, wider ascospores in the Pachysporaria-type II, and the absence of secondary metabolites. Rinodinazeorina differs from Rinodinahypobadia Sheard by areolate and brownish thallus, non-pruinose apothecia, colorless and wider parathecium, narrower paraphyses with non-pigmented and unswollen tips, longer and narrower ascospores with angular to globose lumina, and the absence of pannarin. Molecular analyses employing internal transcribed spacer (ITS) sequences strongly support the two new species to be unique in the genus Rinodina. An updated key is provided to assist in the identification of all 63 taxa in Rinodina of the far eastern Asia.

Project description:BackgroundLichens, traditionally considered as a simple partnership primarily between mycobiont and photobiont, are, in reality, complex holobionts comprised of a multitude of microorganisms. Lichen mycobiome represents fungal community residing within lichen thalli. While it is acknowledged that factors like the host lichen species and environmental conditions influence the structure of the lichen mycobiome, the existing research remains insufficient. To investigate which factor, host genus or location, has a greater impact on the lichen mycobiome, we conducted a comparative analysis of mycobiomes within Parmelia and Peltigera collected from both Turkey and South Korea, using high-throughput sequencing based on internal transcribed spacer region amplification.ResultsOverall, the lichen mycobiome was dominated by Capnodiales (Dothideomycetes), regardless of host or location. At the order level, the taxonomic composition was not significantly different according to lichen genus host or geographical distance. Hierarchical clustering of the top 100 abundant ASVs did not clearly indicate whether the lichen mycobiome was more influenced by host genus or location. Analyses of community similarity and partitioning variables revealed that the structure of the lichen mycobiome is more significantly influenced by location than by host genus. When analyzing the core mycobiome by host genus, the Peltigera mycobiome contained more ASV members than the Parmelia mycobiome. These two core mycobiomes also share common fungal strains, including basidiomycete yeast. Additionally, we used chi-squared tests to identify host genus-specialists and location-specialists.ConclusionsBy comparing lichen mycobiomes of the same genera across different countries, our study advances our comprehension of these microbial communities. Our study elucidates that, although host species play a contributory role, geographic distance exerts a more pronounced impact on the structure of lichen mycobiome. We have made foundational contributions to understanding the lichen mycobiome occupying ecologically crucial niches. We anticipate that broader global-scale investigations into the fungal community structures will provide more detailed insights into fungal residents within lichens.
