Two new Periconia species (Pleosporales, Ascomycota) in China

mycolabadmin

Scientists discovered two new fungal species belonging to the genus Periconia in China. These fungi were collected from freshwater streams and corn plants in Guangxi and Yunnan provinces. Using genetic analysis and microscopy, researchers confirmed these as previously unknown species and named them Periconia guangxiense and Periconia xishuangbannaensis. This discovery adds to our understanding of fungal diversity in China and shows that many fungal species remain yet to be discovered.

Deciphering the morphological, molecular, and pathogenic variability in Fusarium species associated with potato dry rot disease

mycolabadmin

Researchers studied potato dry rot disease in India by collecting diseased potatoes from storage facilities and identifying the fungal pathogens responsible. They found that three Fusarium fungi species cause this disease, with Fusarium sambucinum being the most aggressive and damaging. The study provides important information for farmers and agricultural scientists to better control this disease and reduce potato losses during storage.

Triangularia manubriata sp. Nov.: A Novel Fungal Species Belonging to the Family Podosporaceae Isolated from Soil in Korea

mycolabadmin

Scientists in Korea discovered a new fungal species living in soil, named Triangularia manubriata. The fungus was identified using microscopic observation and DNA analysis, revealing it had unique features compared to related species. This discovery is the first report of the Triangularia genus in Korea and may help researchers understand the diversity of soil fungi and their potential useful applications.

A New Species and Eight New Records of Ascomycetes from Freshwater Niches in Korea

mycolabadmin

Scientists discovered a new fungal species and eight species new to South Korea while studying fungi in freshwater habitats. These fungi are important decomposers that break down plant material in aquatic environments. The study used modern genetic analysis to identify and describe these species, expanding our knowledge of the fungal diversity in Korean freshwater ecosystems.

Morphophylogenetic evidence reveals four new fungal species within Tetraplosphaeriaceae (Pleosporales, Ascomycota) from tropical and subtropical forest in China

mycolabadmin

Scientists discovered four new species of fungi in the tropical and subtropical forests of southern China. These fungi belong to the Tetraplosphaeriaceae family and were found on decaying wood and bamboo. The researchers identified them using both microscopic examination and DNA analysis, comparing them with similar known species.

Characterization and Biological Characteristics of Alternaria, Botryosphaeria, Pestalotiopsis, and Trichothecium Species Associated with Postharvest Loquat Fruit Rot in Yunnan, China

mycolabadmin

Researchers in China identified four types of fungal pathogens responsible for loquat fruit rot after harvest. These fungi cause different symptoms ranging from ring-shaped spots to soft decay, with infection rates between 4-12%. The study confirmed each pathogen’s ability to cause disease and found that some are more aggressive than others. This research helps growers understand what causes loquat spoilage and suggests that careful handling and cool storage can reduce losses.

First Report of Fusarium avenaceum Causing Blight on Juniperus formosana in China: Morphological and Molecular Characterization

mycolabadmin

Juniperus formosana is a beautiful ornamental plant used in landscaping. In October 2024, researchers discovered that a fungus called Fusarium avenaceum was causing a blight disease on these plants in Kaili City, China, making the needles turn yellow and wither. Through detailed examination of the fungus under a microscope and DNA testing, scientists confirmed this is the first time this particular fungus has been found causing this disease on Juniperus formosana in China.

Morphological and molecular identification of Schizophyllum commune causing storage bulb rot disease of Lanzhou edible lily in China and its biological characteristics

mycolabadmin

Researchers in China identified Schizophyllum commune as a fungal pathogen causing rot in stored edible lily bulbs, marking the first report of this disease. The fungus was identified using microscopic examination and genetic sequencing, and was shown to cause 100% infection on lily bulbs. The study found that the fungus grows best at 30°C with high humidity and darkness, providing important information for controlling this storage disease that causes significant crop losses.

Comparative Study and Transcriptomic Analysis on the Antifungal Mechanism of Ag Nanoparticles and Nanowires Against Trichosporon asahii

mycolabadmin

Researchers compared two types of tiny silver particles (nanoparticles and nanowires) as potential treatments for a dangerous fungal infection caused by Trichosporon asahii. Silver nanowires were found to be more effective than nanoparticles at killing the fungus by damaging its cell membranes and disrupting its energy production. The study identified 15 key genes involved in how silver nanowires attack the fungus, suggesting these nanomaterials could become useful alternatives to traditional antifungal drugs.

Ophiostoma babimostense and Sporothrix europaea (Ascomycota, Ophiostomatales), two new ophiostomatalean species, associated with ambrosia and bark beetles in Norway and Poland

mycolabadmin

Scientists discovered two new species of fungi that live in association with beetles in European forests. These fungi, Ophiostoma babimostense and Sporothrix europaea, were found in infested wood and pine shoots in Norway and Poland. The fungi were identified using microscopic examination and DNA analysis, revealing they belong to distinct groups within their respective fungal families. This discovery adds to our understanding of forest fungal diversity and beetle-fungus relationships.
