Horticultural plants are essential natural resources upon which human survival relies, offering diverse means of sustenance, including food, medicine, chemical raw materials, construction materials, landscaping, cultural significance, and tourism. In recent years, the widespread and increasingly harmful fungal diseases in horticultural plants have prompted this study to investigate the diversity and composition of their pathogenic fungi. Over the past six years (2019 to 2024), diseased tissues from horticultural plants in southwestern China were collected and assessed using measurements based on both morphological characteristics and phylogenetic analyses involving combined multi-locus sequence data. A total of 38 fungi were classified into two phyla, Ascomycota and Basidiomycota, and four classes: Sordariomycetes (Amphisphaeriales, Diaporthales, Glomerellales, Hypocreales, and Phyllachorales), Dothideomycetes (Botryosphaeriales, Capnodiales, Cladosporiales, Mycosphaerellales, Myriangiales, and Pleosporales), Exobasidiomycetes (Exobasidiales), and Leotiomycetes (Helotiales), totaling 13 orders. In this paper, we propose one new genus in Pleosporales (Paramassarina) and 13 new species, namely Colletotrichum cymbidiumdis, Conidiocarpus cinnamomeus, Cladosporium viciae, Cytospora sichuanense, Diaporthe erythrinae, Exosporium rhapidis, Fumagospora cinnamomi, Neocosmospora phalaenopsidis, Neoscytalidium hylocereum-undulatum, Paramassarina euonymicola, Paraphoma populi, Phaeosphaer...
