The polyphasic approach reveals two new species and two new records of Nigrospora (Apiosporaceae, Amphisphaeriales) associated with Aquilaria sinensis from China

mycolabadmin

Researchers discovered two new types of fungi (Nigrospora guangxiensis and N. pubeiensis) living inside agarwood trees in southern China. These fungi, along with two previously known species, were identified using both microscopic observations and genetic analysis. The findings help us better understand which fungi live in agarwood trees and how they might contribute to producing the valuable aromatic resin known as agarwood, which is highly prized in traditional medicine and perfumery.

Morphological and phylogenetic analyses reveal two new species of Tubeufia (Tubeufiales, Tubeufiaceae) from freshwater habitats in China

mycolabadmin

Scientists have discovered two previously unknown fungal species in freshwater streams in Hainan Province, China. These fungi, named Tubeufia yanuodaensis and Tubeufia yinggelingensis, belong to a group called helicosporous hyphomycetes that break down decaying wood in water. The researchers identified these new species by comparing their DNA sequences and physical characteristics with existing known species.

Optimizing a modified cetyltrimethylammonium bromide protocol for fungal DNA extraction: Insights from multilocus gene amplification

mycolabadmin

Researchers developed an improved method for extracting fungal DNA that is faster, cheaper, and safer than current commercial kits. The new protocol works by using a special chemical solution and simple crushing tools instead of expensive equipment like liquid nitrogen or bead beaters. They tested it on 40 different fungal species found in dry fruits and successfully identified them all using genetic markers, showing the method could help diagnose fungal diseases in plants, animals, and humans.

Complete genome sequence of Diaporthe vaccinii Shear, a fungal isolated from blueberry

mycolabadmin

Scientists have sequenced the complete genetic blueprint of a fungus called Diaporthe vaccinii that causes serious disease in blueberry plants. Using advanced DNA sequencing technology, they created a high-quality map of the fungus’s 60.2 million base pair genome. This genetic information will help researchers understand how the fungus causes disease and potentially develop better ways to protect blueberry crops from this costly plant pathogen.

Exploring fungal pathogens to control the plant invasive Rubus niveus on Galapagos Island San Cristobal

mycolabadmin

Scientists in the Galapagos Islands are working to control an invasive raspberry plant (Rubus niveus) that has taken over about 30,000 hectares and is damaging native species. Rather than using costly manual removal or herbicides, researchers isolated and tested five different fungi found naturally on diseased raspberry plants to see if they could be used as biological control agents. These five fungi—including species like Colletotrichum and Fusarium—showed promise by causing leaf damage to the raspberry plant, offering hope for a more sustainable pest management solution.

A novel, cheap and easy preparing selective medium for isolation of Pythium species

mycolabadmin

Researchers have created an inexpensive and easy-to-use growth medium called FANS that effectively isolates disease-causing Pythium fungi from soil and water samples. Unlike expensive laboratory media containing toxic chemicals, FANS uses affordable pharmaceutical antibiotics costing about $11.55 per liter. This new medium successfully prevents contamination from other fungi and bacteria while promoting Pythium growth, making it especially valuable for scientists in developing countries studying plant diseases and pythiosis infections.

Two new Periconia species (Pleosporales, Ascomycota) in China

mycolabadmin

Scientists discovered two previously unknown fungal species from the genus Periconia in China. One species was found growing on decaying wood in a freshwater stream in Guangxi Province, while the other was isolated from dead corn leaves in Yunnan Province. Through detailed microscopic examination and genetic testing, the researchers confirmed these are distinct new species with unique characteristics that set them apart from similar known species.

New records of powdery mildew fungi on stone fruits from India

mycolabadmin

Researchers in Kashmir have identified three types of powdery mildew fungi that infect peach, plum, and apricot trees. These are new diseases documented in India and Asia for these important fruit crops. Scientists used both traditional microscopy and modern DNA sequencing to identify the fungi, providing farmers with accurate information needed to manage these plant diseases effectively.

Deep cutaneous fungal infection in an immunocompetent individual caused by a biological pesticide: a rare case report

mycolabadmin

A 66-year-old farmer developed recurring skin infections over 10 years from exposure to a biological pesticide containing a fungus called Purpureocillium lilacinum. Although this fungus is generally safe for healthy people, this case shows it can cause serious skin infections with prolonged exposure. The patient was successfully treated with antifungal medication over three months. This case highlights the importance of proper safety measures when working with biological pesticides.

Revealing structure and shaping priorities in plant and fungal cell wall architecture via solid-state NMR

mycolabadmin

This review explains how scientists use a special type of microscopy called solid-state NMR to study the protective outer layers of fungi and plants. The research shows that fungal pathogens can cleverly rearrange their cell walls to resist antifungal medicines, and that plants carefully organize their cell walls during growth by forming specific connections between different molecules. Understanding these structures at the molecular level could help develop better antifungal treatments and improve how we use plant biomass for biofuels and materials.
