Diversity within the Hygrophorus agathosmus group (Basidiomycota, Agaricales) in Northern Europe

The North European species of the Hygrophorus agathosmus group in subsection Tephroleuci were studied. Three new species are identified based on morphology, ecology and sequence data. Two species are associated with Pinus spp. One of these is described here as H. suaveolens, while the other one is only known from one locality in the Nordic countries and seems to have a more South...

Three new species of Stigmatodiscus from Mallorca (Spain)

During a survey on corticolous Dothideomycetes in Mallorca, several collections with ascomata, asci, and ascospores matching the genus Stigmatodiscus (Stigmatodiscales, Dothideomycetes) were revealed, which did not fit any described species. Therefore, these collections were cultured and sequenced, and a multigene matrix of four loci (nuc18S-ITS-28S rDNA, rpb2, tef1 and tub2) was...

Studies on the biologically active secondary metabolites of the new spider parasitic fungus Gibellula gamsii

Numerous gatherings of a new species of the genus Gibellula, closely resembling the monotypic, neotropical G. mirabilis were encountered in Thailand. The taxon was cultured successfully although no in vitro sporulation was observed. The new species, Gibellula gamsii, could be distinguished from closely related other Gibellula species on the basis of morphological features and...

Stilbocrea walteri sp. nov., an unusual species of Bionectriaceae

The new species Stilbocrea walteri is described and illustrated from Quercus ilex collected in Portugal. Phylogenetic analyses of LSU rDNA, rpb1, rpb2 and tef1 sequence matrices place S. walteri in the Bionectriaceae, Hypocreales, within a clade of specimens morphologically identified as Stilbocrea macrostoma, the generic type of Stilbocrea. Stilbocrea walteri differs from S...

A new genus, Desertispora, and a new species, Diversispora sabulosa, in the family Diversisporaceae (order Diversisporales, subphylum Glomeromycotina)

Phylogenetic analyses of sequences of the SSU–ITS–LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade at the rank of genus in the family Diversisporaceae of the order Diversisporales. The closest natural relatives of the fungus...

Cryptodiscus muriformis and Schizoxylon gilenstamii, two new species of Stictidaceae (Ascomycota)

Cryptodicus muriformis and Schizoxylon gilenstamii (Stictidaceae, Ostropales, Lecanoromycetes, Ascomycota) are described as new to science from collections made in Europe (Sweden, Austria, Switzerland) and North America (Arizona), based on phylogenetic analyses of three loci. Both species show unique morphological characters that distinguish them from closely related species...

Barrmaelia and Entosordaria in Barrmaeliaceae (fam. nov., Xylariales) and critical notes on Anthostomella-like genera based on multigene phylogenies

Phylogenetic analyses of a combined DNA data matrix containing ITS, LSU, rpb2 and tub2 sequences of representative Xylariales revealed that the genus Barrmaelia is a well-defined monophylum, as based on four of its described species (B. macrospora, B. moravica, B. oxyacanthae, B. rhamnicola) and the new species B. rappazii. The generic type of Entosordaria, E. perfidiosa, is...

Resurrection and emendation of the Hypoxylaceae, recognised from a multigene phylogeny of the Xylariales

A multigene phylogeny was constructed, including a significant number of representative species of the main lineages in the Xylariaceae and four DNA loci the internal transcribed spacer region (ITS), the large subunit (LSU) of the nuclear rDNA, the second largest subunit of the RNA polymerase II (RPB2), and beta-tubulin (TUB2). Specimens were selected based on more than a decade...

Generic names in the Orbiliaceae (Orbiliomycetes) and recommendations on which names should be protected or suppressed

A list of all generic names that have been connected with the Orbiliomycetes is provided. Recommendations are made as to which names should be used in accordance with the rules and the different generic concepts. There is a mismatch in the current generic concepts within Orbiliomycetes regarding the two morphs: a narrow concept is used for the asexual morphs, but a broad concept...

Increased CO2 evolution caused by heat treatment in wood-decaying fungi

Wood-decaying fungi are regarded as the main decomposers of woody debris in boreal forests. Given that fungal respiration makes a significant contribution to terrestrial carbon flows, it is important to understand how the wood-decaying fungal metabolism is regulated in relation to different environmental conditions and disturbances. In the present study, we investigated the...

The Genera of Fungi—G3: Aleurocystis, Blastacervulus, Clypeophysalospora, Licrostroma, Neohendersonia and Spumatoria

The current paper represents the third contribution in the Genera of Fungi series, linking the type species of fungal genera to their morphology and DNA sequence data, and, where possible, ecology. In this issue, we have focused on six genera, including macro- and microfungi, four of which the type species is epitypified. In addition, two new families within Pleosporales and...

The plasticity of fungal interactions

Their hyphal structure, the common events of hybridization and horizontal gene transfer, as well as intimate associations with prokaryotes (including endobiotic bacteria) and cooperation with eukaryotes have made fungi very flexible at the genetic, physiological, and ecological levels. It is manifested with the fungal ability to perfectly exploit existing nutrient sources and...

The genus Dentipratulum (Russulales, Auriscalpiaceae): comparative morphology and SEM imaging spore ornamentation split one into three species

The family Auriscalpiaceae (Russulales) includes species forming pileate, stipitate-pileate, effused-reflexed, and resupinate basidiomata. The resupinate basidiomata are characteristic only for the genus Dentipratulum, described to accommodate Dentipratulum bialoviesense, found in the Białowieża Primeval Forest in Poland and later reported from several locations in Eurasia. The...

Four novel Talaromyces species isolated from leaf litter from Colombian Amazon rain forests

Various Talaromyces strains were isolated during a survey of fungi involved in leaf litter decomposition in tropical lowland forests in the Caquetá and Amacayacu areas of the Colombian Amazon. Four new Talaromyces species are described using a polyphasic approach, which includes phenotypic characters, extrolite profiles and phylogenetic analysis of the internal transcribed spacer...

Two novel Aspergillus species from hypersaline soils of The National Park of Lake Urmia, Iran

Two novel Aspergillus species, one belonging to the section Terrei and the other to section Flavipedes, were isolated from hypersaline soils of The National Park of Lake Urmia (Iran) and are here described as Aspergillus iranicus and Aspergillus urmiensis. A polyphasic taxonomic approach comprising extrolite profiles, phenotypic characters and molecular data (beta-tubulin...

Reassessment of Allantonectria, phylogenetic position of Thyronectroidea, and Thyronectria caraganae sp. nov.

The genus Allantonectria is synonymised with Thyronectria, based on morphological and molecular phylogenetic considerations. Investigations of types and fresh collections revealed that Tubercularia concentrica is an earlier name for Sphaeria (syn. Allantonectria) miltina and is thus combined in Thyronectria. Allantonectria yuccae is recognised as a distinct species and...

Teichospora and the Teichosporaceae

A multigene analysis of a combined ITS, LSU, SSU, rpb2 and tef1 sequence data matrix was applied to infer the phylogenetic position of the genus Teichospora in the Pleosporales, based on isolates from freshly collected material of the generic type T. trabicola and several additional species. Phylogenetic analyses revealed that Misturatosphaeria and Floricola are synonyms of...
