Special Issue Information

Dear Colleagues,

Fungi are a distinct, diverse, and ecologically important branch of the tree of life. These hardworking organisms play a vital role in ecosystems as diverse as soil, leaves, rocks, and pelagic zones of the ocean, yet their roles are primarily enacted behind the scenes, literally as hidden layers within their substrate. Fungi are the second-most species-rich group after insects. Thus, it is more challenging to estimate the total number of extant fungi species than that of plants and animals. Fungi play key roles in ecosystems as decomposers, endophytes, mutualists, and pathogens. However, in most cases, the roles of individual fungi in nature are still unknown. Describing and understanding the natural roles of fungal species can help humankind to overcome fungal diseases and better utilize fungal resources. Fungi represent one of the most diverse groups of organisms on the earth, with an indispensable role in the processes and functioning of ecosystems. Despite the early embrace of molecular systematics by mycologists, both the discovery and classification of fungi are still in great flux, particularly among the more basal branches of the tree, whose true diversity is only now coming to light from genomic analyses and environmental DNA surveys.

Abstract
Hydnum is a well-characterized genus in the family Hydnaceae of Cantharellales and is characterized by spinose hymenophores. In this study, an ITS phylogenetic overview and a multilocus (ITS-nrLSU-tef1) phylogenetic tree of Hydnum were carried out. On the basis of morphological characteristics [...] Read more.
Hydnum is a well-characterized genus in the family Hydnaceae of Cantharellales and is characterized by spinose hymenophores. In this study, an ITS phylogenetic overview and a multilocus (ITS-nrLSU-tef1) phylogenetic tree of Hydnum were carried out. On the basis of morphological characteristics and phylogenetic results, seven species from China were confirmed, described, illustrated, and compared with similar species, including three new species, i.e., H. longipes, H. microcarpum, and H. sinorepandum, and four known species, i.e., H. cremeoalbum, H. melitosarxm, H. orientalbidum, and H. pinicola were recorded for the first time in China. A key to the species of Hydnum in China was provided. Full article

Agaricus belongs to Agaricaceae and is one of the most well-known macrofungi, with many edible species. More than 300 Agaricus specimens were collected during a three-year macrofungal resource field investigation in Northeast China. Based on morphological observations and multi-gene (ITS + nrLSU + tef1-a) phylogenetic analyses, six new Agaricus species, i.e., Agaricus aurantipileatus, A. daqinggouensis, A. floccularis, A. griseopileatus, A. sinoagrocyboides, and A. velutinosus, were discovered. These new species belong to four sections within different subgenera: A. (subg. Agaricus) sect. Agaricus, A. (subg. Flavoagaricus) sect. Arvenses, A. (subg. Minores) sect. Minores, and A. (subg. Pseudochitonia) sect. Xanthodermatei. Morphological descriptions, line illustrations, and basidiomata photographs of these new species are provided, and their differences from similar species are discussed. Full article

Three new wood-inhabiting fungal species, Cerioporus yunnanensis, Perenniporiopsis sinensis, and Sarcoporia yunnanensis, are proposed based on a combination of the morphological features and molecular evidence. Cerioporus yunnanensis is characterized by the pileate basidiomata having a fawn brown to black pileal surface, a dimitic hyphal system with clamped generative hyphae, and the presence of the fusoid cystidioles and cylindrical basidiospores (9–12.5 × 3.5–5 µm). Perenniporiopsis sinensis is distinct from the osseous pileus with verrucose, an orange-yellow to dark reddish-brown pileal surface with a cream margin, a trimitic hyphal system with clamped generative hyphae, and the presence of the fusiform cystidioles and ellipsoid basidiospores (9–11 × 5.5–6.5 µm). Sarcoporia yunnanensis is typical of the pileate basidiomata with a salmon to reddish-brown pileal surface, a monomitic hyphal system with clamped generative hyphae, and the presence of the ellipsoid basidiospores (4–5.5 × 2.5–4 µm). Sequences of ITS + nLSU + mt-SSU + TEF1 + RPB1 + RPB2 genes were used for the phylogenetic analyses using maximum likelihood, maximum parsimony, and Bayesian inference methods. The multiple genes with six loci analysis showed that the three new species nested within the order Polyporales, in which C. yunnanensis and P. sinensis nested into the family Polyporaceae, and S. yunnanensis grouped into the family Sarcoporiaceae.

The genus Gongronella is important in agriculture and industry by secreting various natural bioactive metabolites such as chitosanases and organic acids. During the most recent 8 years, a total of 14 new species have been described, remarkably enriching the diversity of this genus. In this study, we added three more new species to this valuable genus, based on a combination of morphological traits and phylogenetic information. Six strains of the genus Gongronella were isolated from soil collected in Hainan Province, China. Phylogenetic analyses of ITS and LSU rDNA sequences grouped these strains into three independent clades. According to their unique morphological characteristics, they were classified as G. multiramosa sp. nov., G. qichaensis sp. nov. and G. oleae sp. nov. The G. multiramosa was characterized by multiple branched sporangiophores and was closely related to G. pedratalhadensis. The G. qichaensis was characterized by obscure collars and closely related to G. butleri, G. hydei and G. banzhaoae. The G. oleae was characterized by the presence of oil droplets in the sporangiospores and was closely related to G. chlamydospora and G. multispora. Their descriptions and illustrations were provided, and their differences from morphological allies and phylogenetic-related species are discussed. Full article
