The ending of dual nomenclatural systems for pleomorphic fungi in 2011 requires the reconciliation competing names, ideally linked through culture based or molecular methods. phylogenetic systematics Hypocreales and its many genera have received extensive study last two decades, however resolution names Cordycipitaceae has not yet been addressed. Here we present a investigation that enables identification this family, provides basis upon which these can be maintained suppressed. taxonomy...
Ophiocordycipitaceae is a diverse family comprising ecologically, economically, medicinally, and culturally important fungi. The was recognized due to the polyphyly of genus Cordyceps broad diversity mostly arthropod-pathogenic lineages Hypocreales. other two cordyceps-like families, Cordycipitaceae Clavicipitaceae, will be revised taxonomically elsewhere. Historically, many species were placed in Cordyceps, but genera have been described this as well, including several based on anamorphic...
Abstract The most frequently encountered symbiont on tree roots is the ascomycete Cenococcum geophilum, only mycorrhizal species within largest fungal class Dothideomycetes, a known for devastating plant pathogens. Here we show that symbiotic genomic idiosyncrasies of ectomycorrhizal basidiomycetes are also present in C. geophilum with symbiosis-induced, taxon-specific genes unknown function and reduced numbers cell wall-degrading enzymes. still holds significant set categories to be...
Environmental DNA surveys reveal that most fungal diversity represents uncultured species. We sequenced the genomes of eight species across tree life using a new single-cell genomics pipeline. show that, despite large variation in genome and gene space recovery from each single amplified (SAG), ≥90% can be recovered by combining multiple SAGs. SAGs provide robust placement for early-diverging lineages infer diploid ancestor fungi. Early-diverging fungi share metabolic deficiencies unique...
Most of the described species in kingdom Fungi are contained two phyla, Ascomycota and Basidiomycota (subkingdom Dikarya). As a result, our understanding biology is heavily influenced by traits observed Dikarya, such as aerial spore dispersal life cycles dominated mitosis haploid nuclei. We now appreciate that comprises numerous phylum-level lineages addition to those but phylogeny genetic characteristics most these poorly understood due limited genome sampling. Here, we addressed major...
Fungal conservation is gaining momentum globally, but many challenges remain. To advance further, more data are needed on fungal diversity across space and time. Fundamental information regarding population sizes, trends, geographic ranges also critical to accurately assess the extinction risk of individual species. However, obtaining these particularly difficult for fungi due their immense diversity, complex problematic taxonomy, cryptic nature. This paper explores how citizen science (CS)...
Intracellular parasitism often results in gene loss, genome reduction, and dependence upon the host for cellular functioning. Rozellomycota is a clade comprising many such parasites related to diverse, highly reduced, animal parasites, Microsporidia. We sequenced nuclear mitochondrial genomes of Paramicrosporidium saccamoebae [Rozellomycota], an intranuclear parasite amoebae. A canonical fungal was recovered from P. that encodes genes necessary complete oxidative phosphorylation pathway...
Based on the taxonomic and nomenclatural recommendations of Quandt et al. (2014) new species combinations are made for Ophiocordycipitaceae. These compliant with recent changes in International Code Nomenclature algae, fungi, plants (ICN) abolition dual system nomenclature fungi. include 10 into Drechmeria, four Harposporium, 23 15 synonymies Ophiocordyceps, one combination Purpureocillium.
Abstract Most empirical research on biological shortfalls has focused vertebrate taxa. This is important given many species in poorly studied groups such as invertebrates, plants, and fungi are predicted to possess high conservation risk. Here, we focus Laboulbeniomycetes: a class of microfungi that understudied. We examined four shortfalls: Linnean (knowledge gaps diversity), Wallacean distributions), Latimerian persistence), the newly introduced Scottian assessments) shortfalls. The...
Abstract Fungi are one of the most diverse groups organisms with an estimated number species in range 2–3 million. The higher-level ranking fungi has been discussed framework molecular phylogenetics since Hibbett et al., and definition higher ranks (e.g., phyla) ‘true fungi’ have revised several subsequent publications. Rapid accumulation novel genomic data advancements now facilitate a robust precise foundation for classification within kingdom. This study provides updated kingdom , drawing...
Two major mycoparasitic lineages, the family Hypocreaceae and genus Tolypocladium, exist within fungal order, Hypocreales. Peptaibiotics are a group of secondary metabolites almost exclusively described from Trichoderma species Hypocreaceae. produced by nonribosomal peptide synthetases (NRPSs) have antibiotic antifungal activities. Tolypocladium mainly truffle parasites, but few insect pathogens. The draft genome sequence parasite ophioglossoides was generated numerous metabolite clusters...
Environmental DNA analyses of fungal communities typically reveal a much larger diversity than can be ascribed to known species. Much this hidden lies within undescribed lineages, especially the early diverging fungi (EDF). Although these EDF often represent new lineages even at phylum level, they have never been cultured, making their morphology and ecology uncertain. One methods characterize uncultured is single-cell sequencing approach. In study, we established large data set sequences by...
Abstract Antarctic soils are unique from those found nearly anywhere else on Earth yet can still harbor a broad diversity of microorganisms able to tolerate the challenging conditions typical continent. For these reasons, microbiologists have been drawn Antarctica for decades. However, our understanding which microbes thrive in and how they do so remains limited. To help resolve knowledge gaps, we analyzed collection 200 archived soils—from Livingston Island Peninsula Cape Hallett northern...
The genus Pseudogymnoascus includes several species frequently isolated from extreme environments worldwide, including cold such as Antarctica. This study describes three new of — P. russus sp. nov. , irelandiae and ramosus —isolated Antarctic soils. These represent the first taxa to be formally described soil samples, expanding our understanding fungal biodiversity in this environment. Microscopic descriptions asexual structures living cultures, along with measurements cultural...
Fungal pathogens commonly originate from benign or non-pathogenic strains living in the natural environment. The recently emerged human pathogen, Candida auris, is one example of a fungus believed to have originated environment and transitioned into clinical setting. To date, however, there limited evidence about origins this species when it began associating with humans. One approach overcome gap reconstruct phylogenetic relationships between (1) isolated non-clinical environments (2) known...
Rust fungi are destructive pathogens in crop plants, having led to epidemics and damaging crops all over the world. The rust Puccinia silphii (Basidiomycota) infects Silphium integrifolium, which is a member of most speciose plant family, Asteraceae. This study analyzes first chromosome-scale genome sequence that any dicot, or species outside Poaceae (grasses). We found it be smallest among available Pucciniales assemblies. Our final assembly was 41.7 Mb size consisted 19 pseudomolecules....
