Simplicillium sinense sp. nov., a novel potential pathogen of tinea faciei

mycolabadmin

Researchers identified a new fungal species called Simplicillium sinense that caused a facial skin infection (tinea faciei) in a 46-year-old man with diabetes. The fungus was resistant to most common antifungal medications but responded well to terbinafine treatment. This is the first reported case of a Simplicillium infection causing facial ringworm, expanding our understanding of rare fungal pathogens.

Sclerotinia rot of Zephyranthes candida caused by Sclerotinia sclerotiorum and Sclerotinia minor

mycolabadmin

Researchers discovered that Zephyranthes candida, a popular ornamental plant, can be infected by two types of fungi: Sclerotinia sclerotiorum and Sclerotinia minor, causing a serious white mold disease. The study identified these pathogens and determined that they grow best in cool, acidic conditions with specific nutrients. This information will help gardeners and farmers develop better strategies to prevent and manage this disease on their plants.

A Novel Subspecies of Didymella acutilobae Causing Leaf Spot in East Asian Hogweed

mycolabadmin

Researchers identified a new fungal disease affecting East Asian hogweed, an edible herb used in traditional medicine. The disease, called leaf spot, was caused by a previously unknown subspecies of fungus named Didymella acutilobae subsp. heraclei. Using genetic analysis and laboratory testing, scientists confirmed this fungus is responsible for infecting hogweed plants in Korean fields. Understanding this pathogen is important for protecting this valuable medicinal plant.

Two New Species of Collybiopsis (Agaricales, Omphalotaceae) from Mudeungsan National Park in Korea

mycolabadmin

Scientists discovered two new species of small mushrooms in Mudeungsan National Park in South Korea. These mushrooms, named Collybiopsis albida and Collybiopsis pini, are decomposer fungi that help break down dead wood and plant material in forests. The researchers used both traditional microscopic examination and modern DNA analysis to confirm these were previously unknown species, highlighting how genetic testing is essential for accurately identifying mushrooms that look similar to each other.

Geoglossum subdifforme sp. nov. and G. simile, Two New Earth Tongues from South Korea

mycolabadmin

Researchers in South Korea discovered two earth tongue fungal species, one new to science. Using DNA analysis and microscopic examination, they confirmed G. simile was previously unknown in Asia and identified a brand new species, G. subdifforme, that grows on Korean islands. These findings expand our understanding of fungal diversity in South Korea and show that molecular analysis is essential for properly identifying these small, dark mushroom-like organisms.

Phylogenetic and Morphological Analysis of a Novel Allocucurbitaria Species Isolated from Lelia decempunctata in South Korea

mycolabadmin

Scientists in South Korea discovered a new fungal species living on a stink bug. By analyzing its genetic material and physical characteristics, they confirmed it was a previously unknown species and named it Allocucurbitaria koreanum. This is the first time this type of fungus has been found associated with insects, suggesting these fungi may have interesting relationships with insects that researchers need to study further.

Acremonium quercivorum (Hypocreales, Sordariomycetes), a New Species from Oak (Quercus spp.) Growing in Algeria

mycolabadmin

Scientists discovered a new fungal species called Acremonium quercivorum found on declining oak trees in Algeria. This fungus was identified through a combination of microscopic examination and DNA analysis comparing it to related species. The discovery represents the first documented case of this particular Acremonium species associated with oak decline in Algeria and contributes to understanding fungal diversity in oak forest ecosystems.

Morpho-molecular analyses reveal two novel species and two new records of Dictyosporiaceae (Pleosporales) from Dulongjiang River in northwestern Yunnan Province, China

mycolabadmin

Scientists discovered and identified four new or newly recorded fungal species from a river in China’s Yunnan Province. These fungi, belonging to the Dictyosporiaceae family, were found growing on submerged wood in the Dulongjiang River. By combining detailed microscopic observation with genetic analysis, researchers confirmed two completely new species and two species not previously recorded in this region, expanding our understanding of freshwater fungal diversity.

The subfamily Chalciporoideae (Boletaceae, Boletales) in China

mycolabadmin

Researchers conducted a comprehensive study of a group of small fungi called Chalciporoideae found throughout China. They discovered four new species and confirmed the presence of 16 different species total using both physical characteristics and DNA analysis. Some of these fungi have interesting properties, like being edible or having potential for mushroom farming. The study provides detailed descriptions and identification keys to help scientists and enthusiasts identify these fungi in the future.

Multi-locus molecular phylogenetic analysis reveals four new species and a new record of Ophiocordyceps (Ophiocordycipitaceae, Hypocreales) on dipteran hosts in Thailand

mycolabadmin

Researchers studying fungi in Thai forests discovered four previously unknown species of Ophiocordyceps that parasitise different types of flies. Using DNA analysis combined with microscopic examination, scientists confirmed these fungi are distinct species, each specialising on particular fly types like houseflies, fruit flies, and robber flies. This research expands our understanding of the remarkable diversity of fungi that naturally control insect populations, which could have implications for biological pest control.
