Morphological and phylogenetic analyses reveal four novel species of Distoseptispora (Distoseptisporaceae, Distoseptisporales) from southern China

mycolabadmin

Scientists discovered four new species of fungi in the forests of southern China that live on dead plant material. These fungi, called Distoseptispora species, were identified using both microscopy and DNA analysis to confirm they are distinct from known species. The study adds to our understanding of fungal diversity in China and provides tools for identifying similar fungi in the future.

Morphology and multigene phylogeny reveal three new species of Distoseptispora (Distoseptisporales, Distoseptisporaceae) on palms (Arecaceae) from peatswamp areas in southern Thailand

mycolabadmin

Scientists studying swamp forests in Thailand discovered three new types of fungi that live on dead palm plants. These fungi, belonging to a group called Distoseptispora, were identified using both microscopic examination and DNA analysis. The research shows how important it is to combine traditional observation methods with modern genetic testing to properly identify new fungal species, particularly in threatened tropical ecosystems.

Complete mitochondrial genomic sequence of Auricularia delicata (Auriculariaceae), an edible Chinese mushroom

mycolabadmin

Scientists have completely sequenced the mitochondrial DNA of Auricularia delicata, a popular edible jelly mushroom used as food and medicine in China and other Asian regions. The genome is 189,696 base pairs long and contains 60 genes. This genetic information helps researchers understand how this mushroom is related to other species and provides a reference for future studies on mushroom cultivation and properties.

First Report of Colletotrichum kahawae Causing Anthracnose on Buckwheat (Fagopyrum tataricum) in China and Biological Characterization of the Pathogen

mycolabadmin

Researchers in China identified a fungus called Colletotrichum kahawae causing a serious disease called anthracnose in buckwheat crops for the first time. The fungus also has the potential to infect other important crops like wheat, oats, potatoes, and corn. Scientists determined the ideal conditions for this fungus to grow and tested its ability to infect different plants. This discovery will help farmers develop better strategies to prevent and manage this disease in buckwheat and other crops.

Structural and functional characterisation and regulatory mechanisms of SWI/SNF and RSC chromatin remodelling complexes in fungi

mycolabadmin

This review examines special protein complexes called SWI/SNF and RSC that help fungi control their genes by rearranging DNA packaging. These complexes are important for fungal survival under stress and for causing disease. The researchers compared these complexes across different fungal species and found both similarities and differences that could help scientists develop new antifungal medicines.

First Report of Trametes hirsuta, Causal Agent White Rot in Avocado Trees Grown in the State of Michoacán, México

mycolabadmin

Researchers discovered that a wood-decay fungus called Trametes hirsuta is causing serious damage to avocado trees in Michoacán, México, the world’s largest avocado-producing region. The fungus infects tree trunks and branches, causing white rot that eventually kills the trees. About 60% of surveyed avocado trees showed signs of infection. Laboratory experiments confirmed that this fungus, previously known only as a decomposer of dead wood, can actively infect and destroy living avocado trees through wounds in the bark.

Clinical and Genomic Insights into Antifungal Resistance in Aspergillus Isolates from Thailand

mycolabadmin

Researchers in Thailand identified a dangerous fungal infection caused by Aspergillus fumigatus that is resistant to azole antifungal drugs. This is the first time this specific drug-resistant strain has been found in a patient sample in Thailand, though it had been previously detected in environmental samples. The study used genetic testing to understand how the fungus developed resistance and found that it has altered genes that help it survive the antifungal medications commonly used to treat infections.

Characterization of Mycoviruses in Armillaria ostoyae and A. cepistipes in the Czech Republic

mycolabadmin

Researchers in the Czech Republic discovered five new viruses infecting Armillaria mushroom fungi that cause root rot in trees. These viruses could potentially be used as biological control agents to reduce tree disease. The study found that some viruses can spread between different Armillaria species, suggesting they move naturally through forest ecosystems.

Candida auris: Outbreak, surveillance and epidemiological monitoring in Northern Greece

mycolabadmin

A dangerous fungus called Candida auris caused an outbreak in hospitals in Northern Greece starting in October 2022. This fungus is particularly concerning because it is resistant to many commonly used antifungal drugs, especially fluconazole. Researchers monitored and tracked the outbreak across multiple hospitals, finding that all cases belonged to the same genetic type (Clade I) and were treatable with certain alternative antifungal medications. The study emphasizes the importance of careful laboratory surveillance and coordinated infection control measures to prevent further spread of this serious infection.

Four new species of Marasmius subgenus Globulares (Marasmiaceae, Agaricales) from subtropical regions of China

mycolabadmin

Scientists discovered four previously unknown species of small mushrooms called Marasmius in subtropical forests of China. These tiny fungi were identified through detailed examination of their physical characteristics and DNA analysis. The new species have distinctive features like different colored caps, spore sizes, and microscopic structures. This discovery adds to our understanding of fungal biodiversity in Chinese subtropical regions.
