The study of Agaricomycetes in the Brazilian Pampa Biome is still incipient, but it very necessary for valorization and preservation activities this area. In terms fungal diversity, least studied biome, with only 84 species already described site, despite great diversity fauna flora that biome presents. objective work to know more about mycodiversity contributing a better understanding distribu...

background: white button mushroom (agaricus bisporus) is a sensitive agricultural crop whose antioxidant properties are decreased during postharvest storage. in this study, the effect of citric acid dipping treatment on bioactive components and antioxidant properties of sliced button mushroom (agaricus bisporus) was investigated. methods: fresh mushrooms soaked in chilled citric acid solution a...

Research on fungal endophytes has expanded dramatically in recent years, but little is known about the diversity and ecological roles of endophytic basidiomycetes. Here we report the analysis of 310 basidiomycetous endophytes isolated from wild and planted populations of the rubber tree genus, Hevea. Species accumulation curves were nonasymptotic, as in the majority of endophyte surveys, indica...

Desert microbes are expected to be substantially sensitive to global environmental changes, such as precipitation changes and elevated nitrogen deposition. However, the effects of precipitation changes and nitrogen enrichment on their diversity and community composition remain poorly understood. We conducted a field experiment over 2 years with multi-level precipitation and nitrogen addition in...

A taxonomic treatment of vinaceous and reddish species of Tubaria (Agaricales) is presented based on morphology and nucleotide sequences. Accessions from western North America, Europe, Central America, the Caribbean and Australia are compared. Phylogenetic analysis of the 25S rRNA gene and internal transcribed spacer (ITS) regions demonstrates that Tubaria is not monophyletic. However the auton...

Three new records of Agaricales species from the Colombian Caribbean region are presented: Agrocybe pediades (Fr.) Fayod, Macrocybe titans (H.E. Bigelow & Kimbr.) Pegler, Lodge Nakasone, and Podaxis pistillaris (L.) Fr. Descriptions, photographs, illustrations macroscopic microscopic features each presented, as well a brief discussion their distribution.

This study provides a first broad systematic treatment of the euagarics as they have recently emerged in phylogenetic systematics. The sample consists of 877 homobasidiomycete taxa and includes approximately one tenth (ca. 700 species) of the known number of species of gilled mushrooms that were traditionally classified in the order Agaricales. About 1000 nucleotide sequences at the 5(') end of...
