Three polypore specimens were collected from Hainan, southern China. They are described and illustrated here as a new species, Amylosporus succulentus, based on a combination of morphological characters and phylogenetic (ITS and nLSU sequences) data. It is characterized by poroid basidiocarps, both simple septate and clamped generative hyphae, hymenial hyphae without clamp connections, and finely asperulate and amyloid basidiospores. These characters are typical for Amylosporus. In the phylogenetic perspective, A. succulentus is closely related to A. campbellii, the generic type, and nested within the Wrightoporiaceae clade. A key to accepted species of Amylosporus worldwide is provided.
