The biogeography of neotropical fungi remains poorly understood. Here, we reconstruct the origins and diversification of neotropical lineages in one of the largest clades of ectomycorrhizal fungi in the globally widespread family Russulaceae.We inferred a supertree of 3,285 operational taxonomic units, representing worldwide internal transcribed sp...

Species of Craterellus (Hydnaceae, Cantharellales) in China are investigated on the basis of morphological and molecular phylogenetic analyses of DNA sequences from nuc 28S rDNA D1-D2 domains (28S) and nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 region. Five species are recognized in China, of which three of them are described as new, viz....

Species of Cantharellus subgenus Cantharellus are interesting and important for their mycorrhizal properties, medicinal values, and edibility. In China, there are many undescribed species of the subgenus. In this study, four new species of subg. Cantharellus, viz. Cantharellus albopileatus, Cantharellus chuiweifanii, Cantharellus pinetorus, and Can...

Fungi play vital roles in ecosystems as endophytes, pathogens and saprobes. The current estimate of fungal diversity is highly uncertain, ranging from 1.5 to 12 million, but only around 150,000 species have been named and classified to date. Since the introduction of DNA based methods for species identification, the number of newly described taxa h...

Fungi are eukaryotes that play essential roles in ecosystems. Among fungi, Basidiomycota is one of the major phyla with more than 40,000 described species. We review species diversity of Basidiomycota from five groups with different lifestyles or habitats: saprobic in grass/forest litter, wood-decaying, yeast-like, ectomycorrhizal, and plant parasi...

The genus Cantharellus, commonly known as chanterelles, has recently been divided into six subgenera; however, wider sampling approaches are needed to clarify the relationships within and between these groups. A phylogenetic overview of Cantharellus subgenus Parvocantharellus in China was inferred based on the large subunit nuclear ribosomal RNA ge...

Basidiomycota constitute a major phylum of the kingdom Fungi, distributed in 4 subphyla, 18 classes, 68 orders and 241 families. Advances in molecular phylogeny over the past years have resulted in numerous changes to their classification at a rapid pace. Consequently, a vast amount of taxonomic information is available in many publications. The we...

The identity of blackening Russula (R. subg. Compactae) from Indian Himalaya has since long remained a mystery and they are often called after their European look‐alikes. Here, a combined approach including morphology and ITS phylogenetic inference resolved the identification of some of these taxa and revealed the discovery of two novel species. Th...

Species boundaries and geographic distribution of corticioid fungi (resupinate Basidiomycota) are often poorly known. Our recent study on Subulicystidium showed that species diversity in this genus is at least twice as high as previously recognized. This re-estimation of the species diversity was based on a study of only a part of the genus. The pr...

This study reports on the discovery of a new subgenus, Russula subg. Glutinosae, having an Eastern North American-East Asian distribution. A multigene phylogeny places this new subgenus sister with strong support to a well-supported clade composed of subgenera Compactae and Archaeae. It holds only two very rare, northern hemisphere species, the Nor...

Since 2007, the quality of Russula descriptions has improved and the use of molecular support for species delimitation and the number of published new species has increased. However, the description style is not consistent and has regional or author-specific patterns. Most recent publications still favour descriptions of spores compared to hymenium...

In Amazonia, the knowledge about Fungi remains patchy and biased towards accessible sites. This is particularly the case in French Guiana where the existing collections have been confined to few coastal localities. Here, we aimed at filling the gaps of knowledge in undersampled areas of this region, particularly focusing on the Basidiomycota. From...

Using the basic GenBank local alignment search tool program (BLAST) to identify fungi collected in a recently protected beech forest at Montricher (Switzerland), the number of ITS sequences associated to the wrong taxon name appears to be around 30%, even higher than previously estimated. Such results rely on the in-depth re-examination of BLAST re...

Mushroom-forming fungi (Agaricomycetes) have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfil diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. Despite the importance of mushroom-forming fungi, large-scale patterns of their evolut...
