On Craterocolla and Ditangium (Sebacinales, Basidiomycota)

In the present paper, we select a neotype for Tremella cerasi and prove that it is conspecific with Ditangium insigne (the genus type of Ditangium). We argue that Ditangium should be restored as a correct genus for T. cerasi, while the currently used generic name Craterocolla is to be treated as its younger synonym. Morphological, ecological and genetic variability of Ditangium...

A novel species and a new combination of Daldinia from Ban Hua Thung community forest in the northern part of Thailand

During a survey of Xylariales in northern Thailand, several specimens with affinities to the genus Daldinia were found and examined for morphological characters, secondary metabolites, and molecular phylogenetic traits. Aside from morphological and chemotaxonomic studies, a multi-locus phylogenetic analysis using internal transcribed spacers regions (ITS) and the large subunit...

Genomic analysis of ant domatia-associated melanized fungi (Chaetothyriales, Ascomycota)

Several species of melanized (“black yeast-like”) fungi in the order Chaetothyriales live in symbiotic association with ants inhabiting plant cavities (domatia) or with ants that use carton-like material for the construction of nests and tunnels. To investigate the genetic basis and evolution of this lifestyle, genomes of a lineage of four chaetothyrialean strains were sequenced...

New sporocarpic taxa in the phylum Glomeromycota: Sclerocarpum amazonicum gen. et sp. nov. in the family Glomeraceae (Glomerales) and Diversispora sporocarpia sp. nov. in the Diversisporaceae (Diversisporales)

Of the nearly 300 species of the phylum Glomeromycota comprising arbuscular mycorrhizal fungi (AMF), only 24 were originally described to form glomoid spores in unorganized sporocarps with a peridium and a gleba, in which the spores are distributed randomly. However, the natural (molecular) phylogeny of most of these species remains unknown. We found unorganized sporocarps of two...

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...

Penicillium hermansii, a new species causing smoky mould in white button mushroom production

Competing fungi in white button mushroom (Agaricus bisporus, champignon) cultivation causes significant episodic losses. One of these competing fungi is known as “smoky mould”. It owes its name to the production of high numbers of spores after the disturbance of compost, which resembles smoke. We investigated strains isolated from smoky mould cases in the Netherlands, UK and...

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...
