is described as a new porphyrellus-like genus of to accommodate , a dark brown to dull lilac/violet, or rarely, nearly black bolete with a series of oxidation reactions progressing from blue to red then nearly black and a dark brown spore deposit. Idiosyncratic blue-green pigment encrustations (cyanogranules) and a similarly colored reaction of the hyphae located on pileus and stipe surfaces are also diagnostic. Phylogenetic analyses of nuclear large-subunit rDNA (nrLSU), translation elongation factor 1-alpha (), and the second largest subunit of RNA polymerase II () infer as a unique generic lineage with two species, one of which is newly described (.

A phylogeny for North American and taxonomic revision of eastern North American taxa.

A multigene phylogenetic assessment of North American species of is presented based on analyses of ITS, and 28S rDNA nucleotide data. This framework enables a systematic revision of the genus for 16 eastern North American species and captures taxonomic and phylogenetic diversity in a global context. A grade of two unusual and poorly known North American species stems from the most recent common ancestor of the genus that gives rise to three core subgroups named here as clades Unicolores, Nothosperma, and Mallocybe.

DNA isolation and genome sequence of the 134-year-old holotype specimen of Peck.

Molecular characterization of type specimens is a powerful tool used in clarifying species identity/circumscription, as well as establishing the taxonomic and phylogenetic status of organisms in question. However, DNA sequencing of aged herbarium collections can be a challenge due to the quantity and quality of DNA still present in the specimens. Herein, we report a custom DNA isolation protocol suitable for processing minute quantities of old specimen tissue and its utilization via high-throughput sequencing technologies to obtain, for the first time, the genome assembly of the 134-year-old holotype of Peck, a North American fleshy pored mushroom of taxonomic and historical significance.

A short story of nearly everything in ().

Fungi are a large and hyper-diverse group with major taxa present in every ecosystem on earth. However, compared to other eukaryotic organisms, their diversity is largely understudied. Since the rise of molecular techniques, new lineages are being discovered at an increasing rate, but many are not accurately characterised.

An Unexpectedly High Number of New (Boletaceae) Species From Northern and Northeastern Thailand.

is a poroid genus in Boletaceae that typically has chocolate brown to reddish brown or purplish brown basidiomata with a finely scaly stipe and produces a reddish brown spore deposit. During the survey on diversity of boletes in Northern and Northeastern Thailand, several collections were obtained. Combined evidence from morphology and phylogenetic analyses of a combined three-gene data set (6, 1 and 2) of the collections along with selected Boletaceae in the group indicated that Thai collections represent seven new species.

Squamanitaceae and three new species of Squamanita parasitic on Amanita basidiomes.

The systematic position of the enigmatically mycoparasitic genus Squamanita (Agaricales, Basidiomycota) together with Cystoderma, Phaeolepiota, Floccularia, and Leucopholiota is largely unknown. Recently they were recognized as Squamanitaceae, but previous studies used few DNA markers from a restricted sample of taxa from the family and lacked a formal taxonomic treatment. In this study, with newly generated sequences of the type of the genus Squamanita, S.

Phylogeny and species delimitation of (), with an emphasis on the Asian species.

is broadly distributed geographically and serves an important ecological function. However, it has been difficult to delimit species within the genus, primarily due to developmental variations and phenotypic plasticity. To elucidate phylogenetic relationships among species within the genus and to understand its species diversity, especially in Asia, materials of the genus collected from five continents (Africa, Asia, Australia, Europe, and North/Central America) were investigated.

Updated taxonomy of LactifluussectionLuteoli: from Australia and from Thailand.

Dierickx & De Crop and Froyen & De Crop are described from eucalypt forests in Queensland, Australia and different forest types in Thailand, respectively. Both species have recently been published on Index Fungorum and fit morphologically and molecularly in L.sect.

Two new species (Boletaceae) from Thailand, with two new combinations of American species.

is a lamellate genus in the family Boletaceae that has been recently described from China based on , the only known species. Typical characters of are reddish-orange to yellowish-red basidiomata, including lamellae, bright yellow basal mycelium and smooth, broadly ellipsoid, ellipsoid to nearly ovoid basidiospores. During our survey on diversity of Boletaceae in Thailand, several yellowish-orange to reddish- or brownish-orange lamellate boletes were collected.

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

Multifurca is a small genus newly established to accommodate lactarioid and russuloid species with some characters reminiscent of corticoid members of Russulaceae. It shows an amphi-pacific distribution with strong preference for the tropical zone of the Northern Hemisphere and thus has particular significance for biogeographical study. Using worldwide samples and three loci (ITS, 28S rDNA and rpb2), we demonstrated that Multifurca is split into two highly supported major clades that are here recognized at the subgeneric level: subg.

A global view of Gyroporus: molecular phylogenetics, diversity patterns, and new species.

Gyroporus (Gyroporaceae, Boletales) is a highly diverse genus of poroid ectomycorrhizal mushrooms with a nearly worldwide distribution. Previous attempts to unravel the diversity within this genus proved difficult due to the presence of semicryptic species and ambiguous results from analysis of ribosomal RNA markers. In this study, we employ a combined morphotaxonomic and phylogenetic approach to delimit species and elucidate geographic and evolutionary patterns in Gyroporus.

The Macrofungi Collection Consortium.

Premise Of The Study: The Macrofungi Collection Consortium (MaCC) is a digitization project funded by the National Science Foundation's Advancing Digitization of Biodiversity Collections program. The main scientific objective of the MaCC project was to provide baseline data for determining the extent and distribution of macrofungal diversity.

Methods And Results: Between 2012 and 2017, 39 participating institutions digitized approximately 1,250,000 specimens of macrofungi from U.

A multi-gene phylogeny of (, ) translated into a new infrageneric classification of the genus.

Infrageneric relations of the genetically diverse milkcap genus (, ) are poorly known. Currently used classification systems still largely reflect the traditional, mainly morphological, characters used for infrageneric delimitations of milkcaps. Increased sampling, combined with small-scale molecular studies, show that this genus is underexplored and in need of revision.

New Porcini (Boletus sect. Boletus) from Australia and Thailand.

Boletus albobrunnescens and B. austroedulis are described as new species in section Boletus from Thailand and Australia respectively. The former is easily characterized by the pure white basidiomata that stain brown.

Phylogenetic overview of the Boletineae.

The generic and sub-generic relationships in the Boletineae (Boletales) were studied using nuclear large subunit (nuc-lsu), translation elongation factor 1-alpha (tef1), and DNA directed RNA polymerase largest subunit (RPB1). The Boletineae, with the exclusion of Hydnomerulius pinastri, was strongly supported and the status of the families Boletaceae and Paxillaceae is discussed. Members of the genus Boletus are found throughout the phylogeny, with the majority not closely related to the type species, Boletus edulis.

Sutorius: a new genus for Boletus eximius.

Sutorius is described as a new genus of Boletaceae to accommodate Boletus robustus originally named illegitimately by C.C. Frost from eastern North America.

Molecular phylogenetics of porcini mushrooms (Boletus section Boletus).

Porcini (Boletus section Boletus: Boletaceae: Boletineae: Boletales) are a conspicuous group of wild, edible mushrooms characterized by fleshy fruiting bodies with a poroid hymenophore that is "stuffed" with white hyphae when young. Their reported distribution is with ectomycorrhizal plants throughout the Northern Hemisphere. Little progress has been made on the systematics of this group using modern molecular phylogenetic tools because sampling has been limited primarily to European species and the genes employed were insufficient to resolve the phylogeny.
