Phyllachora species usually cause leaf tar spot disease associated with living leaves in various hosts. In this study, a sample of stem was collected from Phyllostachys heteroclada forest Ya’an City, Sichuan Province, China. Here we introduce new taxon the genus through using morphology, information on host and multigene phylogeny three genes (LSU, SSU, ITS). Within family Phyllachoraceae, members form five groups maximum likelihood Bayesian phylogenies. The heterocladae clusters eight...

Abstract English walnut ( Juglans regia ), has high economic and ecological value. As an important tree species for eliminating poverty, it is planted in many Provinces of China. In 2021, new pathogenic fungi were observed Guangyuan City, Sichuan Province, The initial symptom leaf infection that the leaves are covered with small black spots, which gradually expand into larger brown spots. Most spots appeared at edges leaves, yellow whorls junction between healthy leaves. isoalted form...

Bletilla striata is an endangered traditional medicinal herb in China. In May 2020, the emergence of white root rot severely impacted quality and yield B. , affecting about 5% plants at plant nurseries Chengdu Academy Agricultural Forestry Sciences. Through a series experiments evaluations, pathogen was identified as Fusarium solani . This first report caused by F. Sichuan, To better understand this disease provide data support for its control, combination morphological, molecular...

Phyllachora (Phyllachoraceae, Phyllachorales) species are parasitic fungi with a wide global distribution, causing tar spots on plants. In this study, we describe three newly discovered species: chongzhouensis, neidongensis, and huiliensis from Poaceae in China. These were characterized using morphological traits multi-locus phylogeny based the internal transcribed spacer region (ITS) intervening 5.8S rRNA gene, large subunit of gene (LSU), 18S ribosomal RNA (SSU). Three known P. chloridis,...

In the present study, we surveyed ascomycetes from bamboo of Phyllostachys across Sichuan Province, China. A biphasic approach based on morphological characteristics and multigene phylogeny confirmed seven species, including one new genus, two five host record species. novel genus Paralloneottiosporina is introduced to accommodate Pa. sichuanensis that was collected leaves violascens. Moreover, newly species Bifusisporella isolated P. edulis, were recorded bamboos, four belonging Apiospora,...

In this paper, Claviformispora gen. nov. in Linocarpaceae is introduced from Phyllostachys heteroclada Sichuan Province, China. The new genus characterised by its distinct morphological characters, such as ostiole with periphyses, asci a thick doughnut-shaped, J- apical ring and clavate ascospore without septum-like band appendage. Maximum Likelihood Bayesian Inference phylogenetic analyses, based on DNA sequence data ITS, LSU, SSU TEF-1α regions, provide further evidence that the fungus...

In Sichuan province, walnuts, consisting of Juglans regia, sigillata, and the hybrid J. regia × are commercially important edible nuts, is most widespread plant. To date, diversity distribution fungi inhabiting on have not received enough attention, although there been studies focusing pathogens from fruit stem. order to update checklist associated with a survey three species 15 representative regions in was conducted. this article, ten distributed two classes Ascomycota (Dothideomycetes...

As an important nonwood bioresource, fishscale bamboo (Phyllostachys heteroclada Oliver) is widely distributed in the subtropical region of China. Rhombic-spot disease, caused by Neostagonosporella sichuanensis, one most serious diseases that threatens health. However, there limited knowledge about how rhombic-spot disease influences diversity and structures phyllosphere fungal communities. In this study, we investigated communities from stems, branches, leaves during a outbreak using 18S...

This study led to the discovery of three entomopathogenic fungi associated with Kuwanaspis howardi, a scale insect on Phyllostachys heteroclada (fishscale bamboo) and Pleioblastus amarus (bitter in China. Two these species belong Podonectria: P. kuwanaspidis X.L. Xu & C.L. Yang sp. nov. novae-zelandiae Dingley. The new has wider thicker setae, longer asci, ascospores, more septa as compared similar Podonectria species. morphs extant is confirmed based sexual asexual morphologies. Maximum...

Twenty-four representative melon varieties and six parental cultivars were examined in this study. Among 159 pairs of simple sequence repeat (SSR) primers, 18 SSR core primers with rich polymorphic information, a large number genotypes, the ability to distinguish different selected. A total 113 genotypes detected among 30 experimental materials, an average 6.28 for each pair primers. The information content was on 0.6807, ranging from 0.5618 0.7885. Specific bands materials analyzed, by...

Acremonium arthrinii sp. nov. was collected from Phyllostachys heteroclada in the forest of Sichuan Province, China.
