Hidden treasures of herbaria – even small collections contain a wealth of diversity: the powdery mildews of the North Carolina State Larry F. Grand Mycological Herbarium

mycolabadmin

Scientists examined preserved powdery mildew samples stored in a university herbarium and discovered four previously unknown fungal species using DNA analysis. The study shows that even small museum collections contain valuable hidden biodiversity that cannot be discovered through visual examination alone. This research highlights why it is important to preserve and maintain herbarium collections rather than discard them due to space or funding constraints, as they serve as crucial resources for understanding fungal diversity and disease.

Phylogenetic diversity of Colletotrichum species (Sordariomycetes, Glomerellales, Glomerellaceae) associated with plant diseases in Thailand

mycolabadmin

Researchers identified eight species of Colletotrichum fungi causing plant diseases in Thailand. They discovered two completely new species and found these fungi on 13 additional plant hosts previously unknown. Using DNA analysis, they confirmed the identity of each fungal species and documented their characteristics. This work helps farmers and scientists better identify and manage these damaging plant pathogens.

Superficial abdominal surgical site infection caused by Aspergillus welwitschiae: a case report

mycolabadmin

An elderly woman developed a rare fungal infection in her abdominal surgical wound after surgery for a perforated colon. The infection was caused by Aspergillus welwitschiae, a mold that was initially thought to be a more common species. Doctors treated the infection by surgically removing the infected tissue and giving the patient an antifungal medication called voriconazole. This is the first reported case of this particular mold causing this type of surgical infection.

A Unique Case of Fungal Endometritis Caused by Aspergillus quadrilineatus in an Immunocompetent Woman and Literature Review

mycolabadmin

A 64-year-old woman experienced persistent vaginal bleeding for three months, which was found to be caused by a rare fungal infection (Aspergillus quadrilineatus) in her uterus. Through tissue examination and molecular testing, doctors identified the fungus and found it was sensitive to common antifungal medications. The patient was successfully treated with antifungal medication combined with surgical cleaning of the uterus, making a complete recovery. This case highlights that fungal infections should be considered when patients have abnormal vaginal bleeding, even if they appear otherwise healthy.

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.

Diverse, Cryptic, and Undescribed: Club and Coral Fungi in a Temperate Australian Forest

mycolabadmin

Researchers surveyed fungi in a small forest area near Sydney and found that nearly 90% of the club and coral fungi they discovered were previously unknown to science. By using DNA analysis, they were able to identify cryptic species that look identical but are genetically distinct. This study demonstrates just how much fungal diversity remains undocumented even in well-studied parts of the world, highlighting the need for more comprehensive fungal surveys and database development.

Hidden treasures of herbaria – even small collections contain a wealth of diversity: the powdery mildews of the North Carolina State Larry F. Grand Mycological Herbarium

mycolabadmin

This study examined a collection of powdery mildew fungi preserved in a university herbarium and used DNA analysis to identify which specimens had been misidentified over the years. The researchers found that about 83% of the specimens had incorrect identifications and discovered four completely new species that look very similar to known species but are genetically distinct. The findings show that old museum collections are valuable resources for discovering hidden biodiversity and that we should preserve these collections rather than discard them.

Species diversity of Cytospora associated with forest canker diseases in Xizang (Tibet), China

mycolabadmin

Scientists studying forests in Tibet discovered 23 new species of Cytospora fungi that cause canker diseases in trees like poplars and willows. Using advanced genetic analysis combined with traditional microscopic examination, researchers identified a total of 50 Cytospora species in the region. These fungi cause bark damage and branch death in many important forest trees. Understanding which species are present and how they spread is crucial for protecting Tibet’s valuable forest ecosystems.

Diverse, Cryptic, and Undescribed: Club and Coral Fungi in a Temperate Australian Forest

mycolabadmin

Researchers surveyed mushroom-like fungi called club and coral fungi in a small Australian forest and used DNA testing to identify the species. They found that about 89% of the fungi they discovered were either new species or not yet recorded in scientific databases. This shows that even in a small area, there are many fungal species we have not yet discovered or properly studied.

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.
