Abstract
ABSTRACT Pleosporales is the largest order of Ascomycota which is distributed worldwide. Among the wide range of hosts, Pleosporales species are frequently isolated from palms. During the surveys of palm fungi from 2020 to 2021, rotting tissues of Licuala peltata var. sumawongii, Phoenix roebelenii and Trachycarpus fortunei were collected in Guangzhou, Guangdong Province, China. Fungal isolates were identified based on morphological characteristics and multi-gene phylogenetic analyses. In the present study, we introduce two new species viz. Byssosphaeria guangdongense and Paraconiothyrium guangdongensis. In addition, we introduce a new host record for Trachycarpus fortunei. Photo plates, detailed descriptions, and in-depth phylogenetic analysis results are provided for all identified taxa. Our findings expand the understanding of the fungi that are associated with palm hosts. Moreover, our data will contribute to the knowledge of the biodiversity of South China.
