Abstract
In this study, morphological characteristics, ecological features, and phylogenetic analyses based on nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS), partial nuc rDNA 28S (28S), and the translation elongation factor 1-α (TEF1) were employed to investigate the species diversity of the genus Volvariella in southwestern China. Eight species are recognized, among which are five known species, namely, V. bombycina, V. hypopithys, V. morozovae, V. pulla, and V. volvacea, and three new species described here, namely, V. parvirimosa, V. pilosa, and V. rimosa. Volvariella pulla represents a species new to China. For species delimitation, the size of the basidiomes, the morphology of the pileus, the size of basidiospores, and the morphology of hymenial cystidia are informative. Taxonomic descriptions of the new species are presented, and a key to the eight species from southwestern China is provided.
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.
