“…The use of molecular data has greatly facilitated the clarification of fungal taxonomy, including of sooty moulds, and many taxa have been revised or introduced (Hongsanan et al, 2020; Hyde et al, 2013; Li et al, 2020). At the same time, new sooty mould species are constantly being identified (Hongsanan et al, 2015; Mesquita et al, 2022; Xu et al, 2020). The currently available evidence indicates that sooty moulds are polyphyletic and include species belonging to two different classes, namely, Dothideomycetes and Eurotiomycetes (Chomnunti et al, 2014; Chomnunti, Ko, et al, 2012).…”

Sooty moulds are a widespread group of saprophytic ascomycetes that obtain nutrients from honeydew excreted by sap‐feeding insects and coat plant tissue with mycelia. Research on sooty moulds has focused on fungal morphology and phylogeny‐based taxonomy, but little research has been conducted on the community structure. In this study, the PacBio sequencing platform was used to systematically analyse the fungal and bacterial diversity of the sooty mould community on camphor trees at two sampling sites. Six dominant sooty mould genera were identified, of which three genera of Dothideomycetes were enriched only in diseased samples, while three genera of Eurotiomycetes were present in both healthy and diseased samples. Bacterial diversity and co‐occurrence network analysis indicated that the sooty moulds had an effect on the leaf surface bacterial communities but not on the endophyte communities. There was a close correlation between the six dominant pathogenic groups and bacteria in the soot layer. Transcriptomic data from Cinnamomum camphora samples showed that the sooty moulds that did not penetrate plant cells not only affected plant photosynthesis but also induced plant defence responses. This study systematically studied the microbial community of sooty moulds, indicating the close relationship between sooty moulds and the bacterial communities.
