Currently, our understanding of the fungi associated with Dracaena species is limited. There is a clear need for more comprehensive information, especially in the context of Thailand. In our study, we collected dead Dracaena leaves with fungal structures from limestone outcrops in seven Thai provinces: Chiang Mai, Kanchanaburi, Krabi, Nakhon Si Thammarat, Ratchaburi, Songkhla, and Tak. The fungi in these samples were isolated and identified using a combination of morphological characteristics and a multi-loci phylogeny (ACT, CHS-1, GAPDH, ITS, LSU, and TUB2). We are thrilled to introduce seven taxa belonging to four families within three orders (Chaetosphaeriales, Glomerellales, and Xylariales). Our detailed morphological descriptions and updated phylogenetic trees of two new species (Zygosporium dracaenae, and Z. dracaenicola) and five new host/geographical records (Colletotrichum dracaenophilum, C. gigasporum, C. truncatum, Malaysiasca phaii, and Neoleptosporella camporesiana) represent a significant step forward in our understanding of this field.
