Implantation of Aspergillus Section Flavi in French Maize and Consequences on Aflatoxin Contamination of Maize at Harvest: Three-Year Survey

mycolabadmin

A harmful fungus called Aspergillus that produces cancer-causing toxins (aflatoxins) has become increasingly common in French maize crops over the past three years. Researchers collected and tested maize samples from across France and found that by 2020, about 80% of samples contained this fungus, and 16% had measurable levels of aflatoxins. This is happening because of hotter and drier conditions caused by climate change, which favor the fungus’s growth. The findings suggest that France needs to improve its monitoring and safety measures for maize to protect consumers and farmers.

Is Ischnoderma benzoinum a competitor or contributor to Heterobasidion annosum decomposition of pine and spruce wood? A comparison to Phlebiopsis gigantea

mycolabadmin

This research examined how three wood-decomposing fungi interact when competing for the same wood resources. Scientists tested whether Ischnoderma benzoinum helps or hinders the harmful root rot fungus Heterobasidion annosum in pine and spruce forests. They found that the outcome depends on which fungus isolates are involved and which tree species is affected, with some combinations showing strong competition while others showed cooperative decomposition.

Plasticity of symbiotroph-saprotroph lifestyles of Piloderma croceum associated with Quercus robur L

mycolabadmin

This research reveals that a common forest fungus called Piloderma croceum can switch between two different lifestyles: breaking down dead wood to obtain nutrients, and forming beneficial partnerships with living oak tree roots. The study shows that dead wood colonized by this fungus serves as a natural ‘seed bank’ for these fungi, allowing them to later colonize new trees. This discovery suggests that protecting deadwood in forests may indirectly help forests grow healthier by supporting the fungi that help trees absorb nutrients.

Resin outpourings on conifers are inhabited by more members of Nectriaceae (Hypocreales, Sordariomycetes) than previously thought

mycolabadmin

Scientists discovered that conifer tree resins, which protect trees from damage and infections, contain more fungi than previously known. In Polish forests, researchers identified seven fungal strains from resin samples, including two completely new species. These specialized fungi can survive in the harsh, toxic environment of tree resins, revealing that this unique habitat is far more diverse than scientists realized.

Diversity and Ecology of Fungi from Underexplored and Extreme Environments

mycolabadmin

This editorial discusses a special collection of studies exploring fungi that thrive in extreme and challenging environments around the world, from frozen Arctic lakes to salty lagoons and polluted soils. These fungi have evolved remarkable abilities to survive harsh conditions and can even help clean up contaminated environments or support plant growth in degraded soils. Researchers are discovering previously unknown fungal species and understanding how these organisms function in ecosystems, with potential applications for cleaning pollution, improving agriculture, and biotechnology.

Four new species of Beltraniella (Amphisphaeriales, Beltraniaceae) revealed by morphology and phylogenetic analyses from China

mycolabadmin

Scientists discovered four new species of fungi called Beltraniella in southern China. These tiny fungi help break down dead leaves and plant matter in forests, playing an important role in maintaining ecosystem health. The researchers identified these new species by examining their physical characteristics under microscopes and analyzing their DNA sequences. This discovery adds to our understanding of the diverse fungal communities found in tropical and subtropical regions.

The Expanding Truffle Environment: A Study of the Microbial Dynamics in the Old Productive Site and the New Tuber magnatum Picco Habitat

mycolabadmin

Researchers studied how microbial communities (fungi and bacteria) develop in expanding white truffle forests compared to established productive forests in Tuscany, Italy. Over two years, they found that new forest areas have more diverse and unstable microbial communities with rapid colonization by various fungi, while older forests show more stable communities dominated by truffle-associated fungi. The study reveals how forest management practices, like selective cutting, influence the balance between fungi that break down plant material and those that form beneficial relationships with tree roots, suggesting that understanding these microbial dynamics is key to successfully expanding truffle cultivation.

Diversity and biological characteristics of macrofungi of district Bajaur, a remote area of Pakistan in the Hindu Kush range

mycolabadmin

Researchers conducted the first-ever comprehensive survey of mushrooms in the Bajaur district of Pakistan, documenting 51 different species. While many species are edible and nutritious, containing high levels of protein, fiber, and minerals, some are highly poisonous and can cause serious illness or death. The study found that certain mushrooms like Morchella esculenta are already used by local communities as food and medicine, and many other species could potentially be developed for medicinal or culinary use with further research.

Mycotoxins: An ongoing challenge to food safety and security

mycolabadmin

Mycotoxins are poisonous substances produced by fungi that contaminate crops and threaten both human and animal health. Climate change is making the problem worse by creating conditions that favor toxic fungi growth. Scientists are developing better detection methods and recommending integrated farming approaches to reduce contamination and protect food safety globally.

mGem: Submarine mycology—an analog to astromycology

mycolabadmin

Scientists are studying fungi in submarines to better understand fungal health risks for astronauts in space. Both submarines and spacecraft are enclosed environments where fungi can grow, causing infections and other health problems. The same types of fungi found growing in submarines have been detected on the International Space Station. By learning from decades of submarine research, space agencies can better prepare for and prevent fungal-related health issues during long space missions.
