Australian collections of sequestrate Agaricaceae were examined with morphological and molecular data (nuclear DNA from ITS and LSU), and the majority were found to belong to the genera Agaricus and Macrolepiota. Previously described Australian species of Endoptychum are transferred to the appropriate agaricoid genera and several new combinations proposed. Descriptions and illustrations are provided for these and eight new species: Agaricus eburneocanus sp. nov., A. chartaceus sp. nov., A… 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
New sequestrate fungi from Guyana: Jimtrappea guyanensis gen. sp. nov., Castellanea pakaraimophila gen. sp. nov., and Costatisporus cyanescens gen. sp. nov. (Boletaceae, Boletales)
TLDR
Unique morphological features and a molecular phylogenetic analysis of 185 taxa across the order Boletales justify the recognition of the three new genera. Expand
Four new species of sequestrate Inocybe from Chilean Nothofagaceae forests
TLDR
Results of the phylogenetic analysis resolved the four new species of Inocybe as distinct species-level clades with strong support, suggesting that these fungi have convergently evolved sequestrate forms independently. 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
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
Phylogenetic analysis of rDNA sequences indicates that the sequestrate Amogaster viridiglebus is derived from within the agaricoid genus Lepiota (Agaricaceae)
TLDR
The phylogeny indicates that Amogaster viridiglebus is nested in the genus Lepiota, suggesting that this rare species has a saprobic trophic mode and does not form ectomycorrhizae with plants. 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
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
Morphological and molecular characterization of three Agaricus species from tropical Asia (Pakistan, Thailand) reveals a new group in section Xanthodermatei
TLDR
This study describes three species from collections made in Pakistan and Thailand and includes them in a larger analysis using all available ITS data for section Xanthodermatei, a new group that is monophyletic and receives low bootstrap support whereas the two previously known groups receive strong support. Expand
Taxonomy and phylogeny of Macrolepiota: two new species from Brazil
TLDR
Macrolepiota cyanolamellata and M. sabulosa from subtropical and tropical regions, respectively, are proposed as new species as well as molecular phylogenetic analyses of the nuc rDNA internal transcribed spacer region ITS1-5 and the combined data set ITS + nuclear large subunit rDNA (28S) + RNA polymerase II second largest (RPB2).

The position and composition of Macrolepiota within the Agaricaceae and its phylogenetic relationships with other members of the family were investigated, using both molecular (ITS and LSU rDNAExpand
Genera in the family Agaricaceae: evidence from nrITS and nrLSU sequences.
TLDR
The circumscription of the family Agaricaceae, its genera and their characters are investigated, and the monovelangiocarpic Chamaemyces fracidus appears to be basal to the family and provides clues to the morphology of the ancestral AgARicaceae. Expand
Australasian species of Macowanites are sequestrate species of Russula (Russulaceae, Basidiomycota)
TLDR
Nine new species of the agaricoid genus Russula are presented and nomenclatural changes for five previously published Australasian species are proposed. Expand
The genus Macrolepiota (Agaricaceae, Basidiomycota) in China
TLDR
Species of the genus Macrolepiota (Agaricaceae) in China were investigated on the basis of morphology and DNA sequences data to support the new species delimitations and to test the conspecificity between the Chinese specimens and their relatives from other continents. 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.

TLDR
The nLSU rDNA of four Australian taxa, Barcheria willisiana, Agaricus xanthodermus, Leucoagaricus naucinus, and Lepiota discolorata, was sequenced for this study and Parsimony analysis of the sequences placed BarcherIA within an Agarici clade. Expand
