The phylogeny of the genera traditionally classified in the family Pluteaceae (Agaricales, Basidiomycota) was investigated using molecular data from nuclear ribosomal genes (nSSU, ITS, nLSU) and consequences for taxonomy and character evolution were evaluated. The genus Volvariella is polyphyletic, as most of its representatives fall outside the Pluteoid clade and shows affinities to some hygro...

The systematic integrity of European Gymnopus subsect. Levipedes is verified based on anatomic-morphological characters with support from DNA sequences of ITS and translation elongation factor 1-alpha genes. Seven species (G. alpinus, G. aquosus, G. dryophilus - including var. lanipes, G. erythropus, G. fagiphilus, G. hybridus, and G. ocior) belonging to this subsection are included. We clarify...

Wrightoporia accommodates polypores producing finely asperulate and amyloid basidiospores, and causing white rot. Thirty-nine species have been described or transferred to this genus; however, only a few species have been referred to molecular phylogeny. In this study, about 140 worldwide specimens of Wrightoporia s.l. were studied morphologically, and ITS and/or nLSU regions from 37 samples, r...

We explored whether DNA-phylogeny-based and morphology-based genus concepts can be reconciled in the basidiomycete family Phanerochaetaceae. Our results show that macromorphology of fruiting bodies and hymenophore construction do not reflect monophyletic groups. However, by integrating micromorphology and re-defining genera, harmonization of DNA phylogeny and morphological genus concepts is pos...

Antrodia is a polyphyletic genus, comprising brown-rot polypores with annual or short-lived perennial resupinate, dimitic basidiocarps. Here we focus on species that are closely related to Antrodia crassa, and investigate their phylogeny and species delimitation using geographic, ecological, morphological and molecular data (ITS and LSU rDNA, tef1). Phylogenetic analyses distinguished four clad...

Previous studies of morphological variation in the homobasidiomycete Hyphoderma setigerum have lead to suspicions of a species complex. This study explores variation in DNA sequences from the nuclear ribosomal ITS region of 45 specimens from America, Asia, and Europe in a phylogeographic context. Based on molecular analysis, morphological studies, and crossing tests, nine preliminary taxa are s...

BACKGROUND In nature, shooting mechanisms are used for a variety of purposes, including prey capture, defense, and reproduction. This review offers insight into the working principles of shooting mechanisms in fungi, plants, and animals in the light of the specific functional demands that these mechanisms fulfill. METHODS We systematically searched the literature using Scopus and Web of Knowl...

Six species of Cystangium, a genus of sequestrate taxa related to Russula, were collected in Patagonia (Argentina and Chile) during autumn 2001. Two species, C. depauperatum Singer & A.H. Sm. and C. nothofagi (E. Horak) Trappe, Castellano & T. Lebel, were already known from this region, while four new species, C. domingueziae, C. gamundiae, C. grandihyphatum and C. longisterigmatum, are describ...

Phylogenetic relationships among members of the antrodia clade were investigated with molecular data from two nuclear ribosomal DNA regions, LSU and ITS. A total of 123 species representing 26 genera producing a brown rot were included in the present study. Three DNA datasets (combined LSU-ITS dataset, LSU dataset, ITS dataset) comprising sequences of 449 isolates were evaluated with three diff...

Taxonomic and phylogenetic studies on Datronia were carried out. Phylogeny based on ITS, nLSU and RBP2 regions revealed that Datronia in current sense includes species belonging to three distantly related clades in polypores. The Datronia in a restricted sense is proposed for the clade including the type species D. mollis and D. stereoides. Neodatronia gen. nov. was proposed for two new resupin...
