“…Four selected strains were well merged into the clades of three known Alternaria species, A. alternata , A. arborescens and A. gossypina , supported with PP/BS values of 0.97/79, 0.99/99 and 0.95/98, respectively. The other eight strains fell into four well independent clades supported with 0.99–1.00 PP values and 99–100% BP values, close to A. orobanches and A. ovoidea [ 42 , 43 ] in a branch supported with 0.80/73 PP/BS values. The results indicate that the four clades represent four new species.…”

Small-spored Alternaria species have been frequently isolated from diseased leaves of Solanum plants. To clarify the diversity of small-spored Alternaria species, a total of 118 strains were obtained from leaf samples of S. tuberosum and S. lycopersicum in six provinces of China during 2022–2023. Based on morphological characterization and multi-locus phylogenetic analysis of the internal transcribed spacer of the rDNA region (ITS), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), translation elongation factor 1 alpha (TEF1), RNA polymerase second largest subunit (RPB2), Alternaria major allergen gene (Alt a 1), endopolygalacturonase gene (EndoPG) and an anonymous gene region (OPA10-2), seven species were determined, including four novel species and three known species (A. alternata, A. gossypina and A. arborescens). The novel species were described and illustrated as A. longxiensis sp. nov., A. lijiangensis sp. nov., A. lycopersici sp. nov. and A. solanicola sp. nov.. In addition, the pathogenicity of the seven species was evaluated on potato leaves. The species exhibited various aggressiveness, which could help in disease management.

“…Sequence alignment analysis using MAFFT version 7 (https://mafft.cbrc.jp/alignment/software/, accessed on 1 January 2023) [28] was performed to trim sequences to ensure a high degree of sequence alignment [29]. Phylogenetic analysis was conducted through the concatenation of five loci (ITS, TEF1-α, GAPDH, RPB2, and Alt a 1) [30]. Phylogenetic tree construction was conducted based on a combination of sequence maximum likelihood (ML) and Bayesian inference (BI).…”

Celtis sinensis is a highly versatile species that is commonly cultivated in the southern regions of China. In June 2022, leaf spot disease was detected in C. sinensis in Nanjing, Jiangsu, China. Based on morphological characteristics, three isolates were determined to be of the Alternaria species. A phylogenetic analysis of combined ITS, GAPDH, TEF1-α, RPB2, and Alt a 1 sequences identified the three isolates we obtained as Alternaria alternata and A. koreana. We determined the pathogenicity of A. alternata and A. koreana in C. sinensis leaves using inoculation through in vivo experiments. Symptoms of inoculation onset in indoor pots were in accordance with those observed in the open country. A. alternata and A. koreana can grow at 15–35 °C, with the best growth occurring at 25 °C. The findings from fungicide susceptibility experiments demonstrated that A. alternata and A. koreana were the most sensitive to prochloraz, which could offer an effective approach for future prevention and control measures against A. alternata and A. koreana. This study provides the initial step toward further research on A. alternata and A. koreana as pathogens of C. sinensis and provides the stage for future control strategy development.

“…Their life modes include epiphytes, endophytes or parasites on living organisms, hyperparasites on fungi or insects, saprobes, pathogens and lichenised fungi ( Zhang et al 2012 ; Hyde et al 2013 ; Tanaka et al 2015 ; Jaklitsch et al 2016a ; Hongsanan et al 2020 ). Of these, several genera, such as Alternaria , Bipolaris , Didymella , Leptospharia , Parastagonospora , Phaeosphaeria and Pyrenophora , have been reported as plant pathogens causing severe diseases on economic crops ( Quaedvlieg et al 2013 ; Woudenberg et al 2013 , 2014 , 2015 ; Manamgoda et al 2014 ; Ariyawansa et al 2015a , b ; Chen et al 2015 , 2017 ; Tanaka et al 2015 ; El-Demerdash 2018 ; Khiralla et al 2019 ; Bhunjun et al 2020 ; Hongsanan et al 2020 ; Backes et al 2021 ; Bartosiak et al 2021 ; Li et al 2023 ).…”

This article presents the results of an ongoing inventory of Ascomycota in Yunnan, China, carried out as part of the research project series “Exploring ascomycete diversity in Yunnan”. From over 100 samples collected from diverse host substrates, microfungi have been isolated, identified and are currently being documented. The primary objective of this research is to promote the discovery of novel taxa and explore the ascomycete diversity in the region, utilising a morphology-phylogeny approach. This article represents the second series of species descriptions for the project and introduces three undocumented species found in the families Bambusicolaceae, Dictyosporiaceae and Periconiaceae, belonging to the suborder Massarineae (Pleosporales, Dothideomycetes). These novel taxa exhibit typical morphological characteristics of Bambusicola, Periconia and Trichobotrys, leading to their designation as Bambusicola hongheensis, Periconia kunmingensis and Trichobotrys sinensis. Comprehensive multigene phylogenetic analyses were conducted to validate the novelty of these species. The results revealed well-defined clades that are clearly distinct from other related species, providing robust support for their placement within their respective families. Notably, this study unveils the phylogenetic affinity of Trichobotrys within Dictyosporiaceae for the first time. Additionally, the synanamorphism for the genus Trichobotrys is also reported for the first time. Detailed descriptions, illustrations and updated phylogenies of the novel species are provided, and thus presenting a valuable resource for researchers and mycologists interested in the diversity of ascomycetes in Yunnan. By enhancing our understanding of the Ascomycota diversity in this region, this research contributes to the broader field of fungal taxonomy and their phylogenetic understanding.
