Abstract
Leaf samples displaying necrotic lesions were collected from Archidendron lucyi (Fabaceae), Litsea pungens (Lauraceae), and Malus hupehensis (Rosaceae) in China. Fungal strains isolated from these symptomatic tissues were assignable to Colletotrichum. Species delimitation relied on multilocus phylogeny, with colony and morphological characters documented for comparison and formal description. Three new species were identified and described, namely, Colletotrichum archidendri in the dracaenophilum complex and C. litseae and C. brunni in the gloeosporioides complex. Detailed morphological descriptions and illustrations are provided for each species. This study also expands the known host range of Colletotrichum and contributes to the understanding of species diversity within the genus.
期刊介绍：
International in coverage, Mycologia presents recent advances in mycology, emphasizing all aspects of the biology of Fungi and fungus-like organisms, including Lichens, Oomycetes and Slime Molds. The Journal emphasizes subjects including applied biology, biochemistry, cell biology, development, ecology, evolution, genetics, genomics, molecular biology, morphology, new techniques, animal or plant pathology, phylogenetics, physiology, aspects of secondary metabolism, systematics, and ultrastructure. In addition to research articles, reviews and short notes, Mycologia also includes invited papers based on presentations from the Annual Conference of the Mycological Society of America, such as Karling Lectures or Presidential Addresses.
