Isolation and characterization of edible mushroom-forming fungi from Swedish nature

mycolabadmin

Swedish researchers isolated 17 strains of wild edible mushroom-forming fungi from nature and studied how they grow at different temperatures and develop fruiting bodies. They found that commercially cultivated mushroom species grow faster and prefer warmer temperatures than wild species. Several strains successfully produced mushrooms on different growing substrates, particularly on birch pellets, with some performing better than established laboratory strains. All newly isolated strains have been preserved in a research collection for future studies and potential commercial mushroom production.

Two Novel Exophiala Species Isolated from Galls on the Chinese Magnolia-Vine (Schisandra Chinensis) in Korea

mycolabadmin

Scientists in Korea discovered two previously unknown types of black yeast fungi living inside galls (abnormal growths) on Chinese magnolia vines caused by tiny gall midge insects. Using genetic testing and microscopic examination, they identified these as entirely new species of fungi. These fungi appear to have beneficial relationships with their host plants, potentially helping them grow better and resist environmental stress. This discovery adds to our understanding of the diverse fungal species in Korea and their interactions with plants and insects.

Antifungal susceptibility testing of Microsporum canis isolated from the skin of dermatologically healthy cats

mycolabadmin

Researchers found that about 5% of healthy cats in Chile carry a fungal infection called Microsporum canis that can spread to humans. The concerning discovery is that all strains tested were resistant to fluconazole, a commonly used antifungal medication. The study shows that indoor cats are at higher risk of carrying this fungus and suggests that screening healthy cats could help prevent transmission to people who have close contact with them.

Aspergillus in Italian Pistachios: Characterization and Detection of Major Aflatoxigenic Species With a Loop-Mediated Isothermal Amplification Assay

mycolabadmin

Researchers studied pistachio nuts from Italy and found dangerous mold species that produce aflatoxins, harmful toxins that can cause serious health problems. They developed a quick and reliable test using molecular biology techniques to detect these molds in pistachios, even at very low levels of contamination. The test uses specially treated dried primers that remain stable for over a month, making it practical for food safety monitoring in warehouses and markets around the world.

Disseminated Lichtheimia ramosa infection in a Japanese Black calf

mycolabadmin

A young cow developed a severe fungal infection caused by Lichtheimia ramosa, a rare type of mold. The infection spread throughout the cow’s body, affecting the liver and digestive system. The cow had an underdeveloped immune system (thymus hypoplasia) and was given multiple antibiotics for weeks, which actually made the fungal infection worse by killing normal protective bacteria. Despite various treatments, the cow’s condition worsened and it had to be euthanized.

Diversity and Community Structure of Endophytic Fungi Isolated from the Brown Seaweed Sargassum thunbergii in Coastal Regions of Korea

mycolabadmin

Researchers collected brown seaweed samples from six coastal regions in Korea and identified 84 different fungal species living inside the seaweed tissues. These endophytic fungi help protect the seaweed by producing defensive chemicals and improving its ability to withstand environmental stress. The study found that water temperature and oxygen levels in the seawater significantly influence which types of fungi are present in each region, with the Tongyeong region hosting the most diverse fungal community.

Diversity of culturable fungi in six Tibetan Plateau lakes, with descriptions of eight new taxa

mycolabadmin

Scientists collected samples from six high-altitude salt lakes on the Tibetan Plateau and grew fungi in laboratory cultures. They found over 800 fungal strains representing 156 different species. Eight of these species had never been identified before, representing an exciting discovery of new fungi adapted to extreme cold and salty environments.

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

mycolabadmin

Researchers in Korea discovered a new fungal species called Graphium aquaticum and found another species, Graphium carbonarium, living in freshwater environments for the first time. These fungi were previously known only from wood and insects. This discovery expands our understanding of where these fungi can live and highlights the rich fungal diversity in Korean freshwater habitats.

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.

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

mycolabadmin

Researchers found two types of fungi called Graphium in freshwater streams in Korea. One type (Graphium carbonarium) had been found before in other countries but never in Korea. The other type is completely new to science and was named Graphium aquaticum because it lives in water. This discovery is surprising because scientists previously thought these fungi only lived on wood and were spread by beetles, not in freshwater environments.
