Open-access occurrence data are useful for studying spatial patterns of fungi, but often have quality issues. These include errors in taxonomy and geo-coordinates, and incomplete coverage across areas and taxonomic groups. We identify 15 quality issues that can lead to incorrect biogeographic inference, and develop a reproducible pipeline that flags and removes problematic entries. This pipeline tests

Fungal endophyte (FE) communities can be shaped by environmental conditions and/or host-plant affinities. Hawaiʻi's landscape-dominant woody genus Metrosideros (Myrtaceae) comprises several vegetatively distinct taxa that are non-randomly distributed across environments, and their FE communities are poorly known. We examined the relative importance of Metrosideros taxon and environment (elevation)

Woody species encroachment of grasslands globally causes many socioecological impacts, including loss of grazing pastures and decreased biodiversity. Soil microbial communities may partially regulate the pace of shrub encroachment, as plant-microbial interactions can strongly influence plant success. We measured fungal composition and activity under dominant plant species across a grassland to shrubland

Given that forest dieback due to emerging pests is increasing under global warming, understanding the relationships between pests, climate, and forest biodiversity is an urgent priority. In Japan, mass attacks of an ambrosia beetle, vectoring a pathogenic fungus, cause oak wilt outbreaks in recent decades. Here, the associations of oak wilt and climate with wood-inhabiting fungal communities in apparently

Soil-borne pathogens can shape forest communities by lowering seedling survivorship. Many soil pathogens can persist long-term as survival spores, but how long pathogens outlive tree hosts in gap soils and whether they continue to affect seedling survival is uncertain. We studied the presence of oomycetes and evaluated seedling performance in soils near live Prunus serotina trees, and 0.5 and 1.5-y-old

Bark represents a unique microbial habitat. Revealing the interactions among bark-associated microbes is important for understanding their diversity, stability, and function, and how core microbiome influences the health and production of the host plant. We used amplicon sequencing of bark from the medicinal plant Eucommia ulmoides collected across nine distinct biogeographical regions in China, and

Halophytes colonize stressed environments of high salinity. Endophytic symbionts improve growth performance and thus adaptability of host plants in stressed environments. Nevertheless, studies focused on the distribution and assembly patterns of fungal endophyte assemblages of halophytes in high salinity environments are limited. We selected 27 common non-mangrove halophytes across 4 geographic sites

We tested whether the host species identity in grass-Epichloë symbioses affected soil chemical and microbial properties. We grew endophyte infected (E+) and endophyte free (E−) Lolium perenne, Hordeum brevisubulatum and Achnatherum inebrians for 18 months in field plots. In E+ soil of all three grasses, available phosphorus was lower whereas total soil nitrogen was higher. Endophyte effects on soil

Batrachochytrium dendrobatidis is responsible for amphibian declines worldwide. Decreasing the aquatic density of this chytrid through consumption of its infectious zoospores by Cladocera (water fleas) may mitigate the impact of chytridiomycosis. Understanding this predator-prey relationship requires insights in the zoospore ingestion rate of an average water flea, but such data are almost non-existent

To identify potentially suitable areas for the mostly alpine ecological guild of nivicolous (snowbank) myxomycetes, the worldwide distribution of a distinct morphospecies, Physarum albescens, was modelled with a correlative spatial approach using the software MaxEnt from 537 unique occurrence points. Three models were developed, first with only the 19 bioclimatic variables plus elevation from the WorldClim

The spatiotemporal distribution and dynamic changes of species composition of myxomycetes in humid subtropical forests of Houhe National Nature Reserve in southern China were studied by collecting samples of bark and ground litter within four seasons for isolation of myxomycetes in moist chamber cultures and by collecting fruiting bodies in the field from June to October. A total of 725 specimens of

According to our hypothesis, temporal heterogeneity due to seasonality (summer rosette vs. winter rosette) instead of spatial heterogeneity, showed higher influence on both the community and the infection rate of endophytes present in the carnivorous plant Pinguicula moranensis. In addition, the infection rate of endophytic fungi isolated from roots was higher than that observed in leaves although

The environmental distribution of non-obligate orchid mycorrhizal (OM) symbionts belonging to the ‘rhizoctonia’ complex remains elusive. Some of these fungi, indeed, are undetectable in soil outside the host rhizosphere. A manipulation experiment was performed to assess the importance of neighbouring non-orchid plants and soil as possible reservoirs of OM fungi for Spiranthes spiralis, a widespread

Symbiotic interactions between plants and microorganisms have recently become the focus of research on biological invasions. However, the interaction between different symbionts and their consequences in host-plant invasion have been seldom explored. Here, we propose that vertically transmitted fungal endophytes could reduce the dependency of invasive grasses on mycorrhizal fungi allowing host establishment

For fungal cyclic epidemics on annual crops, the pathogen carry-over is an important but poorly documented step. Plant resistance affects the pathogen development within the epidemics but we lack data on the inter-annual transmission of inoculum. For Leptosphaeria maculans on 15 oilseed rape genotypes in field during 4 growing seasons, stem canker severity was visually scored at harvest. The number

To what extent does epiphytic community composition in boreal forests reflect soil nutrient status? To answer this question, we investigated potential links between terrestrial plants and lichen-dominated communities in Picea glauca x engelmannii canopies in south-central British Columbia. We combined original data on vegetational composition in the ground and tree layers with published data on elemental

We provide the first analysis of the fungi associated with a very special habitat, the aeroponic roots found in caves and mines in New Brunswick, Canada. Fungal diversity was assessed by Illumina sequencing using three complementary primer sets targeting ribosomal RNA genes, and roots were identified using the non-coding trnH-psbA spacer. Early colonizing ectomycorrhizal fungi such as Agaricales, Helotiales

We examined whether sporocarp carbon and nitrogen isotope ratios (δ13C and δ15N values) reflected different functional strategies in 15 species of wood decay fungi. In Finnish Picea abies forests, we compared sporocarp δ13C and δ15N against log diameter, proximity to ground, and three wood decay types, specifically brown rot, nonselective white rot, and selective white rot (targeting hemicellulose

Beneficial microbes such as plant mutualistic fungi, hold the promise of ameliorating challenges faced in native plant conservation such as disease management. As an alternative to costly chemical pest control, conservation efforts could potentially harness the benefits of plant mutualistic fungi to aid in defense and disease resistance, but there are few tests of this notion. We set out to test the

Plant hybridization is common and important in ecological and economic contexts, however little is known about the impact of plant hybridization on ectomycorrhizal fungal (EMF) communities in natural habitats. We used a Populus hybrid system (P. angustifolia x P. fremontii) in a heterogeneous riparian landscape to address the hypothesis that EMF communities differ among hybrids and their parental species

Arbuscular mycorrhizal (AM) fungi affect ecosystem processes improving plant tolerance in (hyper)arid/saline environments. However, there are no previous studies on the presence of AM fungi in the Atacama Desert (Northern Chile), the driest desert in the world. Here, we studied the root and rhizosphere in 111 samples of representative plants from three elevation gradients: (i) hyperarid desert (700–2000

Current environmental change predictions forecast intensified drought conditions. It is becoming increasingly evident that plant communities are sensitive to drought and that soil-inhabiting microbial communities vary along precipitation gradients. However, the drought sensitivity of microbial communities in general and that of soil fungi in particular remains unclear, even though understanding their

Although Russula ochroleuca is a common ectomycorrhizal (ECM) species in European forests, its reproduction mode, dispersal range, and population structure remains unknown. Altogether, 462 fruit bodies from three spruce forests (two 15 km apart, one 230 km distant from the first two) were analysed using AFLP markers. A mixed mode of reproduction, with several large genets accompanied by a majority

Leptographium terebrantis has been implicated as a contributing factor of P. taeda decline and mortality over the past several decades. We examined the potential of L. terebrantis to cause decline symptoms and determined the relationship between pathogen spread and the formation of new sapwood. The study was undertaken in a 13-y-old P. taeda plantation using artificial inoculations of fungal-colonized

Understanding the distribution of parasites is crucial for biodiversity conservation. Here, we studied the distribution of the ectoparasitic fungus Laboulbenia formicarum in native and invasive Lasius ants in a 2000 km2 area. We screened over 16,000 ant workers in 478 colonies of five different species. We found that Lab. formicarum was rare in native Lasius species but infected 58% of the colonies

Arbuscular mycorrhizal fungi (AMF) enhance nutrient provision in exchange for carbon. However, a shift from nutrient to carbon limitation, induced by repeated or intense defoliation, can represent a trade-off between plant regrowth and the maintenance of mycorrhiza. The combined effects of AMF, phosphorus and defoliation on growth of Agropyron elongatum (C3 grass, low mycorrhizal responsiveness) and

Fungal endophytes may alter plant responses to the environment, but how does the environment affect the communities of fungal symbionts within plants? We examined the impact of nutrient addition and herbivore exclusion on endophyte communities of the prairie grass Andropogon gerardii in a full factorial field experiment. Fungi were cultured from stems, young leaves, and mature leaves, ITS sequences

Despite the important role of fungi for ecosystems, relatively little is known about the factors underlying the dynamics of their diversity. Moreover, studies do not typically consider their dark diversity: the species absent from an otherwise suitable site. Here, we examined potential drivers of local fungal dark diversity in temperate woodland and open habitats using LiDAR and in-situ field measurements

The pinewood nematode Bursaphelenchus xylophilus, is the pathogenic agent of pine wilt disease and a globally notable pine pest. Despite being a plant pathogen, B. xylophilus has a mycophagous phase during its life cycle. We assessed the capacity for polyphagy of mycetophagous pinewood nematodes, testing which of the common species of fungi in pine trees provide better food and higher population growth

Rapid climate change threatens plant communities. While many studies address the impact of climate change on plants and mechanisms of their resilience to climate stressors, the role of the plant microbiome in aiding plants' adaptation to climate change has been less investigated. We argue here that fungal endophytes, an important constituent of the plant microbiome, may be key to the ability of plants

Beauveria bassiana and Metarhizium anisopliae are two promising microbial agents for biopesticides development against the banana root borer Cosmopolites sordidus. In this study, germination, mycelial growth, and sporulation of six local Cameroonian isolates of those two species were assessed under seven different thermal conditions (13, 15, 20, 25, 29 33, and 37 °C) to select thermo-tolerant isolates

Fairy rings are conspicuous features of the Laramie Basin of southeastern Wyoming. Ten fairy ring sites chosen for intensive study were located using a small plane and 415 whole and partial fairy rings were georeferenced and ground-truthed. Fairy ring forming fungi were identified using a combination of taxonomy and ITS fungal barcode sequence comparisons. Precipitation, vegetation, soil type, elevation

The McMurdo Dry Valleys surface is mainly constituted from unconsolidated permafrost. Despite the combination of cold and dry conditions, transiently wetted soils close to lake edges are hotspots of intense biological activity, that can support the surrounding soil ecosystems in such extreme environments. These soils host simple microbial communities that allow easy characterization of the parameters

Ferns represent the basal group of vascular plants and are known to have fungal interactions with arbuscular mycorrhizal fungi, but diversity of endophytic fungi from ferns is rarely studied. Moreover, fungal diversity associated with ferns is likely underestimated as most studies have been performed based on a microscopic or culture-dependent approach. In this study, we investigated the endophytic

Increasing evidence suggests that elevational gradients of soil fungal richness are highly variable, but few studies have examined how diversity components of each guild contribute to overall fungal diversity. Here, we aimed to disentangle the relationships between total, saprotrophic, and ectomycorrhizal fungal richness, and environmental factors across elevational gradients in cool-temperate montane

Hericium flagellum is a highly host-dependent wood-inhabiting fungus in Europe. Its occurrence is strongly connected to the distribution of silver fir (Abies alba). We analysed available data describing ecological factors, especially habitat, substrate preferences and phenology, which are regarded as drivers of H. flagellum occurrence. We also implemented ecological niche modelling to determine the

Epidemics of Scots pine blister rust, caused by Cronartium pini, have become an increasing problem in northern Finland and Sweden. The biology of the rust fungus is complex, with two different life cycle forms that cannot be morphologically distinguished, and it is unclear to what extent the two forms contribute to the epidemics. Genetic structure of fourteen populations of C. pini were investigated

Crops’ wild relatives host a wide range of microorganisms, including some beneficial species that are not found or are under-represented in the domesticated crops. Our goal was to study the underexplored composition of root-associated fungal communities in endangered wild grapevines. We found high taxonomic diversity representing multiple trophic guilds that include beneficial symbiotrophs and endophytes

We studied the biogeography and community structure of root-associated and ectomycorrhizal fungal communities in two related species of tropical Juglandaceae that have disjunct distributions in Asia and Mesoamerica. We tested the effects of environmental and dispersal factors in structuring root-associated fungi at a regional scale. We used Illumina sequencing to document fungi on the roots of Oreomunnea

Certain fungal endophytes improve plant resistance to biotic stresses in forest trees. In this study, three stem fungal endophytes belonging to classes Cystobasidiomycetes, Eurotiomycetes and Dothideomycetes were selected from 210 isolates for their potential as enhancers of Ulmus minor resistance to Ophiostoma novo-ulmi. We evaluated phenotypic traits of these endophytes that could be beneficial for

Interactions between diverse groups of organisms influence the functioning and diversity of ecosystems. Salient examples of such relationships are those among hypogeous fungi, trees and mycophagous mammals. To investigate the role of small mammals in transporting fungal spores within and outside forests as well as the influence of seasons, habitats and species on small mammal mycophagy, we set up a

Old trees are rare in the landscape, as are many of their associated species. Veteranisation is a method by which attempts are made to create microhabitats, otherwise found only in old trees, in younger trees at an earlier stage than would occur naturally. Here, we analysed the early fungal succession in 6 y-old veteranisation wounds in ca. 100 y old living oak trunks by DNA-barcoding of the wood at

We aimed to evaluate if exotic ectomycorrhizal fungi from exotic pine plantations disperse through non-native, but also native, mammals in a mountain ecosystem devoid of native ECM plants. Among four non-native and three native mammal species, feces of non-native wild boar (Sus scrofa) and brown hare (Lepus europaeus), and native pampa fox (Lycalopex gymnocercus) were selected to inoculate seedlings

With a warming and drying climate, coniferous forests worldwide are increasingly threatened by wildfires. We examined how fire impacts ectomycorrhizal (EM) fungi associated with Pinus ponderosa, an important tree species in western North America. In the biodiverse Madrean Sky Islands, P. ponderosa forests exist on insular mountains separated by arid lands. How do EM fungi in these isolated ranges respond

Fungal endophyte communities are poorly investigated in extreme habitats such as deserts. We used cultivation and Sanger sequencing to investigate the effects of environmental variables on the endophytic fungal communities of eight Iranian desert plants. Host species was the main factor shaping the endophyte composition, while soil type additionally affected endophytes of above- and below-ground organs

Understanding the biogeographic patterns of root-associated fungi and their sensitivity to temperature may improve predictions of future changes in terrestrial biodiversity and associated ecosystem processes, but data are currently limited. Anticipating change will require combining observational data, which predict how climatic factors limit current species distributions, with direct manipulations

Four nematophagous fungi (NF) were identified by traditional and molecular techniques, and their in vitro predatory activity (PA) against Haemonchus contortus (Hc), and Panagrellus redivivus (Pr) was assessed. Additionally, the nematocidal activity (NA) of fungal organic extracts (OEs) obtained from a methanol/dichloromethane system was assessed. Fungi were grown in PDB medium under shaking (SchC)

Vertically transmitted fungal endophytes are common defensive symbionts of cool-season grasses. Protection against herbivores has been generally associated with alkaloids produced in the grass-endophyte symbiosis. However, many other changes occur in host metabolism like the release of VOCs. We aimed at characterizing the profile of volatile organic compounds (VOCs) induced by simultaneous fungal endophyte

Climate change is expected to strongly impact biodiversity in Alpine ecosystems and species distribution modelling is increasingly used to provide anticipatory information to guide conservation. In this study, (1) we quantified the range loss, range gain, range change and range turnover caused by climate change in the genus Peltigera a group of terricolous lichens widespread across the Alps, and then

Understanding the relationship between population genetic structure and phenotypic diversity is a fundamental question in evolutionary biology. Yeasts display wide genetic diversity and exhibit remarkably diverse heterotrophic metabolisms that allow a variety of niche occupations. However, little is known about how intra-species genetic population structure is related to trait diversity in yeasts.

Protected areas with restricted management can provide refugia for fungi, but are usually selected based on conservation strategies for flora and fauna. Despite the important role of fungi in floodplains, they are rarely considered in conservation projects. The SwissFungi database covering all biogeographic regions in Switzerland, and consisting of 84% citizen science data, provided a valuable basis

Latitudinal gradients are linked to the dynamics of infectious diseases. Both prevalence and infection intensity of the amphibian-killing fungus, Batrachochytrium dendrobatidis (Bd), vary with latitude. Here, we tested whether abiotic and biotic factors are associated with Bd infection prevalence and intensity along a large latitudinal gradient across the Brazilian Atlantic Forest. We detected a positive

The factors shaping endophytic fungal assemblages in reproductive organs have been less evaluated than in vegetative organs. Here, the temporal dynamics of fungal endophytes in inflorescences and fruits of olive tree cultivars with contrasting anthracnose susceptibilities was assessed, starting before flowers open until fruit ripening. Fungal diversity assessed by rRNA sequencing of cultivable isolates

Genetic and phenotypic variation among individuals increases population resilience to external disturbances and enables quicker adaptation to changing environments. Since the predominant phase in the fungal lifecycle occurs belowground or within substrates, it is difficult to assess the level of variation in functional traits occurring within species in natural environments. In this study, we investigated

Timing of pruning may affect wound susceptibility to wood-invading fungi, such as those associated with grapevine trunk diseases (GTDs). This study aimed to determine the effect of pruning time on natural fungal infection in six vineyards in Galicia, Spain, during two periods of three months each, from November to February and from February to May by ITS2 high-throughput amplicon sequencing. Fungal

Fungi are key mediators of ecosystem processes in temperate forests. Hence, understanding of fungal community development is central to better understand the mechanisms driving shifts in ecosystem processes during forest succession. We studied fungal communities in soil, rhizosphere and roots in a Central European forest chronosequence (1–137 years) dominated by Fagus sylvatica and Picea abies. We

The growth and yield of crops are severely threatened by drought stress. As the symbiotic partners of plants, the function of the symbiotic interaction between arbuscular mycorrhizal fungi (AM fungi) and endophytic fungi on host drought resistance is still unclear. Through high-throughput sequencing of peanuts cultivated in a natural soil environment with different soil water conditions, our study

Entomopathogenic fungi are widespread in terrestrial ecosystems and can be used as models for studying host-pathogen interactions. However, the associations between fungal virulence and ecosystem abundance, and the importance of virulence for ecological fitness are poorly understood. To study these associations, we investigated five selected strains from a natural community of the entomopathogenic
