The genus Agaricus is known for its medicinal and edible species but also includes toxic species that belong to section Xanthodermatei. Previous phylogenetic reconstruction for temperate species, based on sequence data of nuc rRNA gene (rDNA) internal transcribed spacers (ITS), has revealed two major groups in this section and a possible third lineage for A. pseudopratensis. Recent research in Agaricus has shown that classifications need improving with the addition of tropical taxa. In this… 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
Studies on Agaricus subtilipes, a new cultivatable species from Thailand, incidentally reveal the presence of Agaricus subrufescens in Africa
TLDR
Bayesian and maximum likelihood phylogenetic analyses of internal transcribed spacer (ITS) ribosomal RNA gene showed that this new species is sister to A. subrufescens, a new species from North Thailand that can be domesticated, however further investigations are required to optimize conditions for industrial yields. Expand
An overview of Agaricus section Hondenses and Agaricus section Xanthodermatei with description of eight new species from Pakistan
TLDR
The objectives were to investigate the species diversity of both sections in Pakistan and to give an overview of the major clades, and to reveal eight new species and one new record species of A. Xanthodermatei. Expand
Study in Agaricus subgenus Minores and allied clades reveals a new American subgenus and contrasting phylogenetic patterns in Europe and Greater Mekong Subregion
TLDR
Thirty-eight species of A. Minores from this region of Asia were distributed in multiple clades that successively diverged over the past 24 million years, suggesting a major species diversification following the middle Miocene climatic optimum. Expand
New species of Pseudosperma (Agaricales, Inocybaceae) from Pakistan revealed by morphology and multi-locus phylogenetic reconstruction.
TLDR
Three new species of Pseudosperma came to light during fungal surveys in pine-dominated forests of the western Himalayas in Pakistan, based on morphological and molecular data, and likely share an ectomycorrhizal association with trees in the genus Pinus. Expand
Edible species of Agaricus (Agaricaceae) from Xinjiang Province (Western China)
TLDR
Morphological and phylogenetic comparison with species of five sections of Agaricus possessing the red discolouration trait showed that the specimens belonged to four species, two of which, A. sinodeliciosus sp. Expand
The genus Agaricus in the Caribbean II. Refined phylogeny of Agaricus subg. Spissicaules with description of two new sections and eight new species
TLDR
High levels of both species richness and phylogenetic diversity in the Caribbean region contributed to the refinement of the classification of A. Spissicaules, and eight new species and the four sections to which they belong are described in detail. Expand
A new section and species of AgaricussubgenusPseudochitonia from Thailand
TLDR
According to their distinct morphological characteristics, phylogenetic position and relatively old divergence time, a new section Cymbiformes is proposed and this section is represented by a new species A.angusticystidiatus, characterised by the strong iodoform odour of basidiomes and cymbiform basidiospores. Expand
Underexplored regions of Pakistan yield five new species of Leucoagaricus
TLDR
A phylogeny based on morphology and four DNA regions, including the internal transcribed spacers and D1–D2 domains of the 28S gene of the nuc rDNA, and the gene for RNA polymerase II second largest subunit (RPB2), shows that the new taxa are clustered in a clade representing Leucoagaricus section Rubrotincti subgenus Sericeomyces. Expand
Study in Agaricus section Minores in Pakistan with the description of two new species
TLDR
The number of known species of Agaricus in the country increases to 26, and two novel species of A. sect. 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
Sequestrate species of Agaricus and Macrolepiota from Australia: new species and combinations and their position in a calibrated phylogeny
TLDR
Australian collections of sequestrate Agaricaceae were examined with morphological and molecular data and the majority were found to belong to the genera Agaricus and Macrolepiota, and the sequestrate genus Barcheria is retained as a distinct taxon. Expand
Morphological and molecular characterization of two novel species of Agaricus section Xanthodermatei.
TLDR
Molecular (IT1+ITS2 DNA sequence) and morphological comparisons between eight presumed similar taxa of the section support the elevation of both entities to species rank, and two new entities resembling small forms of A. moelleri and A. xanthodermus are described, which have a phenolic odor and are probably toxic. 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 flocculosipes sp. nov., a new potentially cultivatable species from the palaeotropics
TLDR
Phylogenetic analyses based on ITS sequence data using maximum likelihood, parsimony, and Bayesian analyses all support A. flocculosipes as being a distinct species within section Arvenses, a lineage that contains other edible cultivatable taxa such as Agaricus arvensis andAgaricus subrufescens. Expand
New and rare taxa in Agaricus section Bivelares (Duploannulati)
TLDR
These new taxa and phylogenetic associations represent a substantial augmentation and clarification of the authors' knowledge of section Bivelares; described, sequenced species-level taxa in the northern hemisphere are increased from six to 10, a distinct subsectional lineage is revealed and infraspecific resolution within A. devoniensis is improved.

Agaricus megalosporus: A New Species in Section Minores
TLDR
ITS sequence data analysis by maximum likelihood, unweighted parsimony and Bayesian analysis shows that A. megalosporus should be placed in section Minores. Expand
Agaricus subrufescens: new to Thailand
TLDR
The molecular data indicates the Thai collections cluster in A. subrufescens sensu lato, and the data from macro-and microscopic features are consistent with the characteristics of the species. Expand

TLDR
ITS1‐F/ITS4‐B preferential amplification was shown to be particularly useful for detection and analysis of the basidiomycete component in ectomycorrhizae and in rust‐infected tissues. Expand
