Diversity and pathogenicity of pestalotioid fungi infecting Camellia oleifera in China

mycolabadmin

Tea oil plants in China’s Sichuan Province are being infected by three types of fungi that cause serious diseases like leaf spots and blighting. Researchers identified a new fungal species and found that two previously known species can also infect tea oil plants. All three fungi were tested for their ability to cause disease, and they successfully infected tea oil plant leaves under laboratory conditions.

Taxonomic characterization and cytotoxic potential of Vietnamese Ganoderma ellipsoideum against human breast cancer MCF-7 cells

mycolabadmin

Scientists discovered a mushroom species called Ganoderma ellipsoideum in Vietnam that shows promise in fighting breast cancer. When tested on cancer cells in the laboratory, extracts from this mushroom killed cancer cells effectively. Computer modeling showed that compounds from this mushroom fit perfectly into and block proteins that help cancer cells grow and spread. This discovery suggests the mushroom could be a natural source for developing new cancer drugs.

Larone’s Medically Important Fungi: A Guide to Identification, 7th Edition

mycolabadmin

This is a practical guidebook for identifying disease-causing fungi in medical laboratories. The 7th edition uses color-coding and organized illustrations to help laboratory technicians and doctors quickly identify fungi from patient samples. It includes information about emerging fungal pathogens and is designed to be used as a quick reference at the laboratory bench rather than a comprehensive textbook.

Pseudobaorangia (Boletaceae, Boletales), a new genus for Boletus lakhanpalii

mycolabadmin

Scientists have identified and named a new genus of mushroom called Pseudobaorangia for a species previously misclassified as Boletus lakhanpalii. Using DNA analysis of samples found in China’s Baima Snow Mountain, researchers determined this mushroom is closely related to but distinct from the genus Baorangia. This discovery helps clarify the family relationships of boletes, which are a diverse group of mushrooms found around the world.

Phylogenomic, Morphological, and Phylogenetic Evidence Reveals Five New Species and Two New Host Records of Nectriaceae (Hypocreales) from China

mycolabadmin

Scientists in China discovered five new species of fungi from the Fusarium and Neocosmospora groups, which can affect plants and, in rare cases, humans. These fungi were found in various environments including plant leaves, insects, and other fungi. The researchers used advanced DNA analysis and genetic sequencing techniques to identify these new species and clarify how they relate to each other evolutionarily.

Phylogenetic Analysis of Trichoderma Species Associated with Green Mold Disease on Mushrooms and Two New Pathogens on Ganoderma sichuanense

mycolabadmin

Researchers identified a new species of Trichoderma fungus that causes green mold disease in cultivated medicinal mushrooms, particularly Ganoderma sichuanense. Using DNA analysis and genetic comparison, they showed that this new species belongs to a group of Trichoderma fungi that are close relatives of species used for controlling plant diseases. The study suggests this fungus might have potential as a biocontrol agent while currently being problematic for mushroom farmers in China.

The genus Thaxterogaster (Cortinariaceae): phylogeny and species diversity in Western China

mycolabadmin

Researchers studied mushrooms of the genus Thaxterogaster, which are common fungi found in forests worldwide. This study focused on Western China and identified 15 different species in the region, including 8 species never before described by science. Using DNA analysis combined with traditional microscopy, the team created a family tree showing how these species are related to each other and provided a guide for identifying them.

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

mycolabadmin

Scientists in Korea discovered and identified a new fungal species living in soil, which they named Triangularia manubriata. This fungus belongs to a family of soil-dwelling fungi that help break down organic matter and are important for soil health. The researchers used a combination of physical observations and genetic analysis to confirm it was a previously unknown species, marking the first time this fungal genus has been identified in Korea.

Four New or Newly Recorded Species from Freshwater Habitats in Jiangxi Province, China

mycolabadmin

Scientists surveying freshwater streams in Jiangxi Province, China discovered four fungal species new to the region. Three of these species had never been described before, while one was recorded in China for the first time. Using both microscope observations and DNA analysis, researchers confirmed these findings and classified them within the fungal families Pleurotheciaceae and Pseudodactylariaceae. These discoveries demonstrate how much fungal diversity still remains undiscovered in freshwater ecosystems.

Utilising bryophyte herbarium material as a source of fungal novelty: a case study presenting new records of Bryobroma gymnomitrii (Döbbeler) Döbbeler on Gymnomitrion Corda in Britain and North America

mycolabadmin

Researchers examined over 400 preserved plant specimens from museum collections to find fungi that had been unknowingly collected with liverwort plants. They discovered a small fungus called Bryobroma gymnomitrii in specimens from Britain and Alaska, expanding where scientists knew this fungus lived. This study shows that old museum collections are valuable treasure troves for discovering fungi and understanding how they are distributed around the world, especially as climate change threatens these plants.
