Phylogenetic analyses of 62 isolates of 42 Agaricus and related secotioid species (A. inapertus, Gyrophragmium dunalii and Longula texensis) were conducted based on sequence data of the internal transcribed spacers (ITS) and partial large subunit (LSU) of ribosomal DNA. Bayesian, maximum likelihood and maximum parsimony analyses were used to reveal evolutionary groups within the genus Agaricus, while molecular clock analyses were carried out to obtain more information about the divergence times… Expand

Multigene Phylogeny and Morphology Reveal Three Novel Species and a Novel Record of Agaricus From Northern Thailand
TLDR
It was proposed that A. pallidobrunneus was discovered in Thailand for the first time and remains an incertae sedis in Agaricus subg. Expand
The new genus Auritella from Africa and Australia (Inocybaceae, Agaricales): molecular systematics, taxonomy and historical biogeography
TLDR
A maximum likelihood tree using rpb2 and nLSU-rDNA nucleotide sequences depicts the phylogenetic relationships of five of the seven species of the new genus Auritella, of which the Australian taxa form a monophyletic group. Expand
rDNA based analysis of autochtonous fungal species from Serbia
TLDR
Identification of six autochtonous fungal species in Serbia was done by comparison between morphological and molecular data ofFungal species, as well as information obtained from phylogenetic tree, and it showed that within genera Marasmius and Ganoderma determinations are usually in accordance, but for proper species delimitation both approaches should be used. Expand
Molecular survey of basidiomycetes and divergence time estimation: An Indian perspective
TLDR
D divergence time estimation shows that Dacrymycetes evolved in the Neoproterozoic Era and Hymenochaetales diverged from Agaricomycete during the Silurian period. Expand
Agaricus section Xanthodermatei: a phylogenetic reconstruction with commentary on taxa
TLDR
DNA sequences from the ITS1+2 region of the nuclear rDNA were analyzed to identify and characterize phylogenetically distinct entities and to construct a hypothesis of relationships, indicating that the traditional sectional characters noted above are good unifying characters that appear to have arisen only once within Agaricus. Expand
Agaricus section Xanthodermatei: a phylogenetic reconstruction with commentary on taxa
TLDR
DNA sequences from the ITS1+2 region of the nuclear rDNA are analyzed to identify and characterize phylogenetically distinct entities and to construct a hypothesis of relationships, both among members of Agaricus section Xanthodermatei and with representative taxa from other sections of the genus. Expand
Notes on Agaricus section Duploannulati using molecular and morphological data.
The position of several endemic and rare species in Agaricus sect. Dulploannulati and the limits of the section were investigated by analysis of sequence data from the ribosomal DNA ITS. The results… Expand
Towards standardizing taxonomic ranks using divergence times – a case study for reconstruction of the Agaricus taxonomic system
TLDR
ITS data, while useful at lower taxonomic levels, are of limited value for inferring deeper phylogenetic relationships and it is suggested that the establishment of a standardized taxonomic system based on divergence times could result in a more objective, and biologically more meaningful, taxonomic ranking of fungi. Expand
Molecular diversity assessment of arctic and boreal Agaricus taxa
TLDR
The results show that the proportion of section Arvenses taxa is particularly high in the boreal forest and hypo-arctic (low arctic) regions, whereas the genus is represented by section Agaricus in high arctic habitats, and suggest that the commercially important A. bisporus occurs naturally in the Boreal region of interior Alaska, substantially expanding the known northern limit of the species. Expand
Major clades in tropical Agaricus
TLDR
Diversity in this study used approximately 50 distinct species from a small area of northern Thailand, most probably being novel species, indicating that Agaricus is a species-rich genus in the tropics as well as in temperate regions. Expand

PHYLOGENETIC RELATIONSHIPS OF AGARICUS SPECIES BASED ON ITS-2 AND 28S RIBOSOMAL DNA SEQUENCES
TLDR
Results suggest that Agaricus may be monophyletic, but fur- ther tests should include taxa from the subgenera Langagaricus and Conioagaricus, andPhylogenetic hypotheses are given for taxa that have been difficult to classify based on other forms of data, including the placement of A. bernardii.

A phylogeny of the genus Agaricus based on mitochondrial atp6 sequences
TLDR
The complete mitochondrial atp6 gene of A. bisporus is presented and a phylogeny of linear mitochondrial plasmid found in these same species indicates separate evolutionary histories for the plasmids and their host mitochondria. Expand
Phylogeny of the Genus Agaricus Inferred from Restriction Analysis of Enzymatically Amplified Ribosomal DNA
TLDR
This is the first comprehensive attempt at systematically resolving the entire genus Agaricus using modern techniques for molecular genetic analysis and indicates that previous taxonomic schemes, based on morphological characters, are in need of revision. Expand
A phylogenetic reconstruction and emendation of Agaricus section Duploannulatae
TLDR
DNA sequence data from the ITS segments of the nuclear ribosomal DNA region was used to identify characters shared by section Duploannulatae, to further delimit species-level taxa within the section, and to develop a phylogenetic hypothesis. Expand
Phylogenetic relationships of agaric fungi based on nuclear large subunit ribosomal DNA sequences.
TLDR
Phylogenetic relationships of mushrooms and their relatives within the order Agaricales were addressed by using nuclear large subunit ribosomal DNA sequences to provide a framework for future systematics studies in the Agaricalses and suggestions for analyzing large molecular data sets. Expand
PHYLOGENETIC DIVERSITY IN SHIITAKE INFERRED FROM NUCLEAR RIBOSOMAL DNA SEQUENCES
TLDR
Results suggest that there are four independent lineages of shiitake in Asia-Australasia, which provides partial support for the morphologically based species concepts. Expand
One hundred and seventeen clades of euagarics.
TLDR
This study provides a first broad systematic treatment of the euagarics as they have recently emerged in phylogenetic systematics and recognizes eight major groups of homobasidiomycetes that cut across traditional lines of classification, in agreement with other recent phylogenetic studies. Expand

Phylogenetic relationships in Ganoderma inferred from the internal transcribed spacers and 25S ribosomal DNA sequences
TLDR
Phylogenetic analysis of the combined data sets of the divergent domain D2 of the 25S ribosomal RNA gene and of the internal transcribed spacers indicated that sub- genus Elfvingia was monophyletic, whereas sections Characoderma and Phaeonema were not. Expand
Population and phylogenetic structure within the Agaricus subfloccosus complex
