Abstract

Abstract: Aquilaria (Thymelaeaceae), a tropical and subtropical plant, is one of the main genera that can produce agarwood. Aquilaria sinensis and A. yunnanensis are native Chinese tree species, and A. sinensis is China's main agarwood source. Agarwood is a non-timber forest product with high economic and medicinal value. First-grade agarwood is sold as much as $100,000 per kilogram. There has been little research on the saprobic fungi associated with Aquilaria, with only eleven records having been reported. In the present study, ten terrestrial saprobic fungi associated with A. sinensis and A. yunnanensis were collected in China. Based on morphological and phylogenetic studies, these ten collections are introduced herein as one new genus (Aquilariomyces), nine new species—Aquilariomyces aquilariae, Corynespora aquilariae, Melomastia maomingensis, Nigrograna aquilariae, Parathyridariella aquilariae, Peroneutypa maomingensis, Phaeoseptum aquilariae, Pseudothyridariella aquilariae, and Triangularia aquilariae, and one known species (Camarographium clematisidis). Descriptions, illustrations of morphological characteristics, photo plates, phylogenetic trees, and the results of a pairwise homoplasy index test (PHI) test results are provided.

Key words: agarwood fungi, Aquilaria, Dothideomycetes, morphology, saprobes, Sordariomycetes, 10 new taxa, Thymelaeaceae
