This paper illustrates two species in the lichen-forming family Arthoniaceae from southern China, including a new species of Herpothallon, H. fibrosum L.L. Liu & Lu L. Zhang and a new record of Cryptothecia, C. striata G. Thor for China. Herpothallon fibrosum has fluffy, cylindrical pseudoisidia, like a bundle of fiber, and psoromic acid and confluentic acid are present. Furthermore, the new record of Cryptothecia striata has been identified by morphological, anatomical, chemical, and molecular studies. The systematic position of the two species was clarified by the molecular sequence data from the small subunit of the mitochondrial ribosomal DNA (mtSSU). Detailed taxonomic descriptions, chemical characters, comparisons, and discussion of the characteristics of similar species are provided for the two species; the relationship between Cryptothecia and Herpothallon is also discussed here.

In addition, L. magenta is reported for the first time as a new record in China, characterized by small and round ascomata. The descriptions, distribution and phylogenetic analysis of the respective species have been actualized and a key to the Letrouitia species known from China is provided. Full article

Recent work has suggested exceptional species-level diversity in the lichen-forming Lecanora polytropa complex (Lecanoraceae, Ascomycota). However, biogeographic patterns and the spatial structuring of this diversity remains poorly known. To investigate diversity across multiple spatial scales, we sampled members of this species complex from two distinct regions—the Pacific Coast Ranges in southern Alaska, USA, and montane habitats in Spain. We also included sequence data from several species within this complex that were recently described from populations in France. Using the standard DNA barcoding marker and a sequence-based species delimitation approach (ASAP), we inferred a total of 123 candidate species (SHs) within the Lecanora polytropa complex, 32 of which were sampled for the first time here. Of 123 SHs, 21 had documented intercontinental distributions, while the vast majority were found at much smaller spatial scales. From our samples collected from Alaska, USA, and Spain, representing 36 SHs, we found high genetic diversity occurring within each sampled site, but limited overlap among all sites. Mountain ranges in both regions had high proportions of endemic lineages, with the highest diversity and endemism occurring in mountain ranges in Spain. Our sequence data generally support the recent taxonomic proposals, and an integrative taxonomy may help partly resolve the taxonomic conundrums within this hyper-diverse lineage. Full article

The lichenized fungal genus Fissurina with mostly slit-like lirellae, belongs to Graphidaceae and is mainly distributed in tropical and subtropical regions. A total of 17 Fissurina species have been reported from China. During a survey of the lichen diversity of southern China, a new species Fissurina wuyinensis K.J. Shi, Z.F. Jia and X. Zhao, sp. nov. was found, which is characterized by a corticolous thallus without detected secondary substances, uncarbonized lirellae, and an exposed disc with pruina, muriform and amyloid ascospores. Furthermore, two new records of F. pseudostromatica, F. subcomparimuralis have been identified by morphological, anatomical, chemical and molecular studies. Phylogenetic analyses of three loci (ITS, nuLSU and mtSSU) supported the position of these species within Fissurina. Detailed morphological descriptions as well as high-resolution photographs of the morphology and anatomy of the three species are provided, as well as a comparison and discussion of the characteristics of similar species. The studied specimens were deposited in the Fungarium of the College of Life Sciences, Liaocheng University (LCUF). Full article

In order to provide data for lichenologists studying taxonomy, Chaenothecopsis xishuiensis is supported and proposed as a new species from China based on phenotypic, molecular, and metabolite data. It is characterised by leprose thallus, single, conical to hemispherical apothecia, nonbranching stipe, cylindrical, eight-spored asci, and nonseptate and brown spores, and this lichenised fungus contains atranorin and zeorin in the thallus. In addition, Lecanora pseudargentata is reported for the first time as a new record from China. This species is characterised by red-brown to dark brown apothecial discs, eight-spored asci, nonseptate, hyaline spores, and the presence of atranorin and gangaleoidin. The biological activity of its lichen substances is discussed. Full article

Lendemeriella luteoaurantia B.G. Lee is described as a new lichen species from South Korea. The new species is identified by smaller, yellow-orange apothecia, larger ascospores with wider septum width, and the absence of Cinereorufa-green pigment and teloschistin, different from the closest species, L. aureopruinosa I.V. Frolov, Vondrák, Arup, Konoreva, S. Chesnokov, Yakovczenko and Davydov in morphology and chemistry. Molecular phylogeny employing internal transcribed spacer (nuITS), nuclear large subunit ribosomal RNA (nuLSU), and mitochondrial small subunit (mtSSU) sequences strongly supports the new species as nonidentical in the genus Lendemeriella. A preliminary key is provided to assist in the identification of all 10 species of Lendemeriella. Full article

Rinodina is a lichenized fungal genus belonging to the Physciaceae, with c. 300 species worldwide. Nearly a century ago, Zahlbruckner described five species of the genus Rinodina from Southwest China. The type collections were the only records for these species. In the present study, new records for four of these species: Rinodina cornutula, R. globulans, R. handelii, and R. setschwana, and a recently described species, R. pluriloculata, are documented based on specimens collected from the holotype localities. Furthermore, one new species was discovered: Rinodina hengduanensis, characterized by areolate to subsquamulose thallus, jigsaw-like areoles, lecanorine apothecium, and Dirinaria-type ascospores. Rinodina setschwana is transferred to the genus Buellia based on its morphology, chemistry, and phylogeny and proposed as Buellia setschwana. We provide detailed morphological descriptions, pictures, and molecular phylogenetic analyses. Full article
