<i>Aroramyces sinensis</i>, a new ectomycorrhizal species associated with <i>Quercus</i> from subtropical Asia, and a worldwide key to <i>Aroramyces</i> (<i>Hysterangiaceae</i>)

Aroramyces sinensis is described as new to science from subtropical region of southwestern China. Molecular and morphological characters separate this new hypogeous species from other existing taxa in the genus Aroramyces. Phylogenetic analyses based on partial nuc 28S rDNA (LSU) and translation elongation factor 1-α (tef1) sequences show that A. sinensis is closely related to A. gelatinosporus. This serves as the first report of Aroramyces from Asia. In addition, we provide a worldwide key to all recognized Aroramyces species.
