Taxonomic reintroduction of (Taphrinales, Ascomycota) associated with as one of five well defined European species colonizing alders.

Phylogenetic analysis of four DNA regions (ITS, LSU, mtSSU and ) supported the existence of five European species which colonise in Europe. In addition to previously well-defined species, is, for the first time recognised, by molecular study as a species related to . Analysis of publicly available sequences of barcoding regions suggested that is only associated with and no other species colonize this host tree.

Environmental heterogeneity structures root-associated fungal communities in Daphne arbuscula (Thymelaeaceae), a shrub adapted to extreme rocky habitats.

Rocky habitats, globally distributed ecosystems, harbour diverse biota, including numerous endemic and endangered species. Vascular plants thriving in these environments face challenging abiotic conditions, requiring diverse morphological and physiological adaptations. Their engagement with the surrounding microbiomes is, however, equally vital for their adaptation, fitness, and long-term survival.

Three new species in subsection supported by genealogical and phenotypic coherence.

is a subsection composed of species of ectomycorrhizal fungi belonging to the hyperdiverse and cosmopolitan genus (Russulales). Species of are recognized by their fishy or shrimp odor, browning context, and a green reaction to iron sulfate. However, species delimitation has traditionally relied on morphology and analysis of limited molecular data.

Phylogeny of Look-Alikes Reveals a Convergent Morphology Evolution and a New Species .

is known as a common wood inhabiting fungus widely distributed throughout the Northern Hemisphere. There have been contrasting opinions about the delimitation and taxonomic treatment of the similar species . Our phylogeny did not support the close relationship of these two morphologically similar species and the grouping of collections labelled by both names within each phylogenetic species reflects unreliable species delimitations in the traditional literatures.

Two new Russula species (fungi) from dry dipterocarp forest in Thailand suggest niche specialization to this habitat type.

Dry dipterocarp forests are among the most common habitat types in Thailand. Russulaceae are known as common ectomycorrhizal symbionts of Dipterocarpaceae trees in this type of habitat. The present study aims to identify collections of Russula subsection Amoeninae Buyck from dry dipterocarp forests in Thailand.

Description of the Fifth New Species of subsect. from Pakistan Indicates Local Diversity Hotspot of Ectomycorrhizal Fungi in Southwestern Himalayas.

subsect. is morphologically and phylogenetically well-defined lineage of ectomycorrhizal fungi associated with arctic, boreal, temperate and Mediterranean habitats of Northern Hemisphere. Based on phylogenetic distance among species, it seems that this group diversified relatively recently.

Morphological and genetic diversification of , sp. nov., along the Isthmus of Panama.

Species of are ubiquitous members of ectomycorrhizal fungal communities in tropical ecosystems. However, an important part of the total tropical diversity of this genus and its biogeographic patterns is unknown due to the lack of studies on in tropical ecosystems. We combined molecular, morphological, ecological, and biogeographic data to elaborate concepts for two new subspecies of (subsection ).

Taxonomic revision of Russula subsection Amoeninae from South Korea.

Russula subsection Amoeninae is morphologically defined by a dry velvety pileus surface, a complete absence of cystidia with heteromorphous contents in all tissues, and spores without amyloid suprahilar spot. Thirty-four species within subsection Amoeninae have been published worldwide. Although most species in South Korea have been assigned European or North American names, recent molecular studies have shown that species from different continents are not conspecific.

Genetic Diversity, Ochratoxin A and Fumonisin Profiles of Strains of Section Isolated from Dried Vine Fruits.

We investigated ochratoxin A (OTA) contamination in raisin samples purchased from Slovak markets and determined the diversity of black-spored aspergilli as potential OTA and fumonisin (FB1 and FB2) producers. The taxonomic identification was performed using sequences of the nuclear ITS1-5.8s-ITS2 region, the calmodulin and beta-tubulin genes.

Phylogenetic study documents different speciation mechanisms within the lineage in boreal and arctic environments of the Northern Hemisphere.

The lineage is a morphologically and phylogenetically well-defined group of ectomycorrhizal fungi occurring in various climatic areas. In this study we performed a multi-locus phylogenetic study based on collections from boreal, alpine and arctic habitats of Europe and Western North America, subalpine collections from the southeast Himalayas and collections from subtropical coniferous forests of Pakistan. European and North American collections are nearly identical and probably represent a single species named distributed from the Alps to the Rocky Mountains.
