Addition of three new species of Xylariomycetidae fungi on bamboo from Southern China

Abstract

In our ongoing research on bambusicolous Xylariomycetidae fungi, three new microfungi taxa were collected and identified as members of the genera Amphibambusa, Arecophila, and Nigropunctata. Amphibambusa aureae sp. nov., Arecophila gaofengensis sp. nov., and Nigropunctata xiaohensis sp. nov. are introduced based on morphological comparisons and phylogenetic analyses using combined ITS, LSU, tub2, and tef1α loci. Comprehensive morphological descriptions, illustrations, and a phylogenetic tree showcasing the placement of these new taxa are provided. Additionally, keys to Amphibambusa and Nigropunctata are provided.
