Genome sequencing and analysis of isolates of Cytospora sorbicola and Cytospora plurivora associated with almond and peach canker

mycolabadmin

This study provides genetic blueprints for two dangerous fungal pathogens that damage almond and peach orchards by causing canker diseases. Scientists sequenced the complete genomes of these fungi and identified genes responsible for their ability to infect plants, finding that they’ve evolved special abilities to survive in nutrient-poor bark tissue. This genetic information could help farmers develop fruit trees resistant to these infections. The research also clarifies the identity of a newly described fungal species, showing it’s actually the same as a previously known species.

Two new species of Stilbochaeta (Chaetosphaeriaceae, Chaetosphaeriales) from freshwater and terrestrial habitats in China

mycolabadmin

Scientists discovered two previously unknown species of fungi called Stilbochaeta in China. They used DNA analysis and microscopic examination to confirm these were new species distinct from known fungi. One species was found in a freshwater stream, while the other was discovered on decaying wood in a forest. This discovery increases the known diversity of these small fungi and shows how important it is to study different ecosystems around the world.

Genetic sequencing of the airborne fungal spectrum and air quality at a public hospital in Mexico City

mycolabadmin

Researchers tested the air inside and outside a Mexico City hospital to identify harmful fungi that could make patients sick. Using two different sampling methods, they found 27 different fungal species, including dangerous ones like Aspergillus fumigatus that cause serious infections especially in people with weakened immune systems. The study shows that hospitals need better air monitoring systems to protect vulnerable patients from these airborne infections.

Prevalence of Candida and Other Yeasts in Vulvovaginal Infections during Pregnancy: A 10-Year Serbian Survey

mycolabadmin

This study examined yeast infections in pregnant Serbian women over 10 years, finding that nearly half had positive tests. While Candida albicans was most common, many other yeast species were also identified, some of which are resistant to common antifungal medications. Using advanced laboratory techniques (MALDI-TOF MS), researchers found more accurate identification was possible, which is important since different yeasts require different treatments, especially during pregnancy when some medications can harm the baby.

Diversity and Ecology of Fungi from Underexplored and Extreme Environments

mycolabadmin

This editorial introduces a special issue on fungi that survive in harsh environments like deserts, salty water, polar regions, and polluted sites. Scientists are discovering that these remarkable fungi can help clean up contaminated soil, support plant growth under stress, and may have pharmaceutical uses. The research brings together classical mycology with modern genetic techniques to unlock the untapped potential of these extreme-environment fungi.

Discovery of the first resinicolous fungus in Mycosphaerellales (Dothideomycetes): Resinomelania communis from conifer resins in Poland

mycolabadmin

Scientists discovered a new fungus species living on tree resins from conifer trees in Poland. This fungus, named Resinomelania communis, represents the first known fungus in its evolutionary group that specializes in living on sticky tree resins. The discovery was made by identifying 13 fungal strains from four different conifer species using DNA analysis and studying their physical characteristics.

A New Species and a New Record of Graphium from Freshwater Environment in Korea

mycolabadmin

Researchers in Korea discovered two types of fungi from Graphium genus in freshwater rivers and streams. One was identified as Graphium carbonarium, previously unknown in Korea, while the other two isolates represent an entirely new species named Graphium aquaticum. This finding is significant because Graphium fungi were previously thought to live only on wood and in association with insects, making freshwater an unexpected and new habitat for these organisms.

Morphological and Phylogenetic Characterization of Raffaelea xyleboricola sp. nov. from Xyleborus Beetles in Korea

mycolabadmin

Researchers discovered a new fungal species living inside ambrosia beetles collected from Korean apple orchards. By examining the fungus under a microscope and analyzing its genetic material, they confirmed it was previously unknown to science. This fungus, named Raffaelea xyleboricola, may help scientists better manage beetle-related tree diseases and protect apple orchards.

Identification and antifungal susceptibility patterns of reference yeast strains to novel and conventional agents: a comparative study using CLSI, EUCAST and Sensititre YeastOne methods

mycolabadmin

Researchers compared three different laboratory methods for testing how well antifungal drugs work against common yeast infections. They tested 22 different yeast strains including Candida species using CLSI, EUCAST, and Sensititre YeastOne methods. The methods showed strong agreement overall, but some newer antifungal drugs like ibrexafungerp showed more variation between methods. The findings suggest these methods are reliable for guiding treatment decisions, but further standardization is needed for newer drugs.

Introducing a global database of entomopathogenic fungi and their host associations

mycolabadmin

Scientists have created a global database called EntomoFun 1.0 that brings together information about fungi that naturally infect insects and other arthropods. The database contains nearly 1,800 records of different fungal species and the insects they infect, collected from scientific literature and museum specimens. This resource helps researchers understand where these fungi are found, which insects they target, and how they might be used for pest control or studied for their ecological importance.
