The wild gourmet mushroom Boletus edulis and its close allies are of significant ecological and economic importance. They are found throughout the Northern Hemisphere, but despite their ubiquity there are still many unresolved issues with regard to the taxonomy, systematics and biogeography of this group of mushrooms. Most phylogenetic studies of Boletus so far have characterized samples from North America and Europe and little information is available on samples from other areas, including the…

Multilocus phylogenetic analyses reveal unexpected abundant diversity and significant disjunct distribution pattern of the Hedgehog Mushrooms (Hydnum L.)

This study extensively gathered specimens of Hydnum from Asia, Europe, America and Australasia, and analyzed them by using sequences of four gene fragments, recognizing at least 31 phylogenetic species within Hydnum, 15 of which were reported for the first time.

Phylogenetic analysis reveals the new genus Amoenoboletus from Asia and New Zealand

By careful reexamination of macroscopic and microscopic characters of Boletus granulopunctatus and Xerocomus mcrobbii, a new genus and species Amoenoboletus miraculosus from Sabah, Malaysia is discovered and three new combinations in Amoenobosletus are proposed, and a dichotomous key to species in the genus is provided.

The genus Retiboletus in China

A preliminary biogeographical analysis shows that allied species of Retiboletus between eastern Asia and North/Central America are common but there are no Retibo letus species common to both continents.

Phylogeny, biogeography and taxonomic re-assessment of Multifurca (Russulaceae, Russulales) using three-locus data

Using worldwide samples and three loci, it is demonstrated that Multifurca is split into two highly supported major clades that are here recognized at the subgeneric level: subg.

Phylogeny and biogeography of the remarkable genus Bondarzewia (Basidiomycota, Russulales)

From the results, it is inferred that the maximum crown age of Bondarzewia is approximately 25.5 million-years-ago and that tropical East Asia is likely to be its ancestral area, with three possible expansions leading to its distribution in North America, Europe and Oceania.

Species Diversity, Phylogeny, Divergence Time, and Biogeography of the Genus Sanghuangporus (Basidiomycota)

The Bayesian uncorrelated lognormal relaxed molecular clock using BEAST and reconstructed ancestral areas indicate that the maximum crown age of Sanghuangporus is approximately 30.85 million years, and the molecular phylogeny strongly supports the monophyly ofSanghuangsporus.

Phylogeny and species delimitation of Flammulina: taxonomic status of winter mushroom in East Asia and a new European species identified using an integrated approach

It is indicated that Enokitake is not identical to the European winter mushroom Flammulina velutipes, and thus should be treated as a separate species, namely Fllammulina filiformis.

Exploring the Relationships between Four New Species of Boletoid Fungi from Northern China and Their Related Species

Four new species of boletoid fungi are introduced in northern China based on the study of their morphology and phylogeny and the evidence and analyses indicated the new species’ relationships with other species within their genera.

Exploring the Species Diversity of Edible Mushrooms in Yunnan, Southwestern China, by DNA Barcoding

The results on both the distinct barcode sequences and the distributions of these sequences should facilitate new mushroom species discovery and forensic authentication of high-valued mushrooms and contribute to the scientific inventory for the management of wild mushroom markets.

The data suggest that populations of A. muscaria later evolved into species, expanded their range in North America and Eurasia, and adapted to the cooling climate.

A phylogenetic study of Boletus section Boletus in Europe

Boletus edulis is defined as a variable species with a wide morphological, ecological and geographic range, and includes several specific and subspecific taxa described in the literature and three other European species that are well delimited species based on morphology and genetic data.

The distribution of Quercus suber chloroplast haplotypes matches the palaeogeographical history of the western Mediterranean

Results demonstrated that cork oak populations have undergone a genetic drift geographically consistent with the Oligocene and Miocene break‐up events of the European–Iberian continental margin and suggested that they have persisted in a number of separate microplates, without detectable chloroplast DNA modifications for a time span of over 15 million years.

A global meta‐analysis of Tuber ITS rDNA sequences: species diversity, host associations and long‐distance dispersal

It is estimated that Tuber contains a minimum of 180 species and species in Excavatum, Maculatum and Rufum clades exhibit preference for angiosperm hosts, whereas those in the Gibbosum clade are preferential towards gymnosperms.

Comparative Chloroplast Genomics Reveals the Evolution of Pinaceae Genera and Subfamilies

The phylogenetic analyses reveal that Cedrus is clustered with Abies–Keteleeria rather than the basal-most genus of Pinaceae and that Cathaya is closer to Pinus than to Picea or Larix–Pseudotsuga, and views on subfamilial classifications differ from previous studies in terms of the rank of Cedrus and with recognition of more than two subfamilies.

Evolutionary history of Serpulaceae (Basidiomycota): molecular phylogeny, historical biogeography and evidence for a single transition of nutritional mode

This study supports the growing understanding that the same geographical barriers that limit plant- and animal dispersal also limit the spread of fungi, as a combination of vicariance and long distance dispersal events are needed to explain the present patterns of distribution in Serpulaceae.

Retiboletus, a new genus for a species-complex in the Boletaceae producing retipolides

The phylogenetic analysis using maximum likelihood suggests that both species are differently distributed, and the results are supported by a previous study of Hellwig (1999), separating three groups in the B. retipes/ornatipes -complex based on chemotaxonomical characters.
