A new fungal species, Septobasidium aquilariae, is proposed based on a combination of morphological features and molecular evidence. The species is characterized by an annual growth habit; a resupinate coriaceous basidiocarp with a cream to pale brown surface; a monomitic hyphal system with thick-walled generative hyphae bearing simple septa; reniform, hyaline, thin-walled, smooth basidiospores measuring 11–19 × 4–7.5 μm; and haustoria consisting of irregularly coiled hyphae. The fungus was found associated with Pseudaulacaspis sp. on Aquilaria sinensis. Sequences of internal transcribed spacer region (ITS) were analysed maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogenies strongly supported S. aquilariae in a monophyletic lineage (ML = 100%; MP = 100%; PP = 1) and grouped with "S. cokeri".
