Reports new species of Colletotrichum in forest trees, suggesting increased species diversity in this genus.
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.
