Abstract
As symbiotic mycorrhizal associates, species within the genus Laccaria play pivotal roles in forest ecosystems, specifically forming ectomycorrhizal relationships with the root systems of various plants. Some Laccaria species are recognized for their edibility, holding potential as a sustainable food source in the context of future food security and dietary diversification. In this study, the species diversity of Laccaria in Yunnan was investigated, and four novel species were identified. Their taxonomical positions and phylogenetic affinities were confirmed through phylogenetic analysis based on ITS, nrLSU, tef1-α, and rpb2 sequence data. Macro- and micro-morphological characteristics of the new species are also given here. Laccaria brownii sp. nov. has a dark to slightly desaturated orange pileus, stipe context broadly fistulose and soft orange, and relatively smaller cheilocystidia and pleurocystidia. Laccaria orangei sp. nov. has a hemispherical to paraboloid pileus, abundant narrowly clavate, flexuose, and branched cheilocystidia. Laccaria ruber sp. nov. pileus is red on the margin, clearly striate on the pileus surface, basidia clavate, mostly four-spored, rarely two-spored. Laccaria stipalba sp. nov. stipe surface is white, long sterigmata (4-13 μm × 2-3 μm), pleurocystidia narrowly clavate to subclavate, flexuose or mucronate, rarely branch. The descriptions, illustrations, and phylogenetic analysis results of the new taxa are provided. In addition, the new taxa are compared with closely related taxa.
期刊介绍:
Journal of Fungi (ISSN 2309-608X) is an international, peer-reviewed scientific open access journal that provides an advanced forum for studies related to pathogenic fungi, fungal biology, and all other aspects of fungal research. The journal publishes reviews, regular research papers, and communications in quarterly issues. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on paper length. Full experimental details must be provided so that the results can be reproduced.
