Molecular and Morphological Evidence Reveals Four New Neocosmospora Species from Dragon Trees in Yunnan Province, China.

ABSTRACT: Neocosmospora (Nectriaceae) is a globally distributed fungal genus, traditionally recognized as a group of plant pathogens, with most members known to cause severe plant diseases. However, recent studies have demonstrated that many of these fungi can also colonize plants endophytically, with certain strains capable of promoting plant growth and stimulating the production of secondary metabolites. In this study, 13 strains of Neocosmospora were isolated from the stems and leaves of Dracaena cambodiana and D. lourei in Yunnan Province, China. To clarify the taxonomic placement of these strains, morphological examination and multi-gene (ITS, nrLSU, tef1, rpb1, and rpb2) phylogenetic analyses were performed. Based on morphological and phylogenetic evidence, four new species are introduced and
