Aleurodiscus tenuissimus and A. tropicus, on dead bamboo, are new species from tropical Asia. Both species have effused basidiocarps and simple-septate generative hyphae. Aleurodiscus tenuissimus, from southern China, lacks acanthophyses and possesses echinulate basidiospores, whereas A. tropicus, from southern China and Vietnam, has abundant acanthophyses and smooth basidiospores. Phylogenetic analyses of the nuc rDNA internal transcribed spacer region sequences (ITS1-5.8S-ITS2 = ITS) support the recognition of the taxa as distinct. The new species are described and illustrated, and a worldwide key to six species of Aleurodiscus on bamboo is provided.
