MycoKeys 121: 1-20, DOI: 10.3897/mycokeys.121.154055 Abstract This study isolated endophytic fungi of the genus Nigrospora from Aquilaria sinensis (Chinese agarwood) in Guangxi, China. Through rigorous morphological comparisons and molecular phylogenetic analyses, we have identified two new species (N. guangxiensis and N. pubeiensis) and two new host-recorded species (N. oryzae and N. camelliae-sinensis). The morphological analysis revealed that the new species align with the genus-level definition of Nigrospora in colony morphology, conidiophores, and conidial characteristics. However, they were distinguished from known species by finer features such as conidial dimensions and conidiogenous structures. For instance, conidiophores in Nigrospora are typically differentiated from hyphae, characterized by dark pigmentation, which is consistent with broader taxonomic descriptions. Molecular phylogeny, based on concatenated datasets of the ITS, TEF 1-α, and TUB 2 loci, showed that N. pubeiensis is most closely related to N. chinensis, while N. guangxiensis forms a distinct basal clade...
