Aspergillus latus: A cryptic causative agent of aspergillosis emerging in Japan

mycolabadmin

Researchers in Japan discovered that a dangerous fungus called Aspergillus latus, previously unknown in the country, has been causing infections since at least 2013. This fungus is difficult to identify because it looks similar to other related species and is actually a hybrid created from two different Aspergillus species. The study found seven cases of this fungus in clinical samples and discovered that it is resistant to some common antifungal medications, making accurate identification crucial for proper patient treatment.

Taxonomy and phylogeny of Cortinarius sect. Anomali in China

mycolabadmin

This research identifies and describes 22 species of Cortinarius mushrooms found in China, including 11 newly discovered species. Scientists used both traditional microscopy and modern DNA analysis to distinguish between similar-looking species and understand how they are related to each other. The study also compares Chinese species with those found in Europe and North America, helping map out how these mushrooms are distributed across the world.

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.

Two new species of Penicillium (Eurotiales, Aspergillaceae) from China based on morphological and molecular analyses

mycolabadmin

Scientists in China discovered and formally described two new species of Penicillium fungi: P. lentum and P. tibetense. These fungi were identified using a combination of physical characteristics and genetic analysis. P. lentum grows slowly with dense colonies and produces a specific branching pattern, while P. tibetense grows rapidly with a different branching structure. This discovery adds to our understanding of fungal diversity in China and demonstrates the importance of using modern molecular methods alongside traditional microscopy in identifying new fungal species.

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.

Endophytic Fungi Isolated from the Marine Macroalga Dictyopteris pacifica in Korea

mycolabadmin

Researchers in Korea discovered three species of fungi living inside a brown seaweed called Dictyopteris pacifica. These fungi were previously unknown in Korea and were identified using genetic analysis. The fungi have mutualistic relationships with the seaweed and may produce compounds useful for medicines and treating diseases.

Differential responses of Cacao pathogens Colletotrichum gloeosporioides and Pestalotiopsis sp. to UVB 305 nm and UVC 275 nm

mycolabadmin

Scientists studied how UV light can be used to fight fungal diseases that harm cacao plants. They found that UVC light (a type of ultraviolet radiation) is much more effective at killing these fungi than UVB light. Some fungi were very resistant to UV treatment, but the researchers discovered that combining UV light with sound waves (sonication) could overcome this resistance, offering a chemical-free way to protect crops.

Various types of mycorrhizal fungi sequences detected in single intracellular vesicles

mycolabadmin

Researchers discovered that single fatty droplet-like structures inside plant roots can contain genetic material from multiple types of fungi, both Glomeromycotina and Mucoromycotina. They developed new molecular tools to detect and identify these fungi without bias. This finding suggests fungi may live together more intimately than previously thought, which could help us better understand how plants get nutrients from fungal partners in soil.

Novel secondary metabolite from a new species of Hypoxylon saxatilis sp. nov. for suppressing bacterial wilt in tomato

mycolabadmin

Scientists discovered a new type of fungus called Hypoxylon saxatilis that produces a natural compound called tetrahydrofuran. This compound effectively kills the bacteria that cause tomato plants to wilt and die. When used on tomato plants in the greenhouse, this fungal extract reduced disease severity by over 83%, offering a safer, environmentally friendly alternative to chemical pesticides for protecting crops.

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

mycolabadmin

Researchers in China discovered that a fungus called Colletotrichum kahawae is causing a serious disease called anthracnose on buckwheat crops in Yunnan Province. This is the first time this particular fungus has been identified on buckwheat in China. Scientists studied how the fungus grows and found it prefers temperatures around 25°C and neutral pH levels. The fungus can also infect other important crops like wheat, corn, potatoes, and oats, which could pose a significant threat to agriculture in the region.
