Nomenclatural review of names published in the fungal genus Dermoloma (Basidiomycota, Agaricales, Tricholomataceae) based on morphological analyses of type specimens

mycolabadmin

Scientists have carefully re-examined nine fungal specimens from the genus Dermoloma that serve as the reference standards for naming these mushroom species. Using detailed microscopic analysis, they found that some specimens previously classified as Dermoloma actually belong to different genera, while others represent distinct species. This work helps clarify the true identity of Dermoloma mushrooms and provides a stable foundation for accurately naming new species discovered in the future.

Bioactive Properties of Selected European Phellinus Species: A Comprehensive Study

mycolabadmin

This research examined 30 samples of medicinal mushrooms from the Phellinus genus collected across Europe, including Poland, Italy, Portugal, Kosovo, and North Macedonia. Scientists found that three species—Phellinus igniarius, Fomitiporia robusta, and Porodaedalea pini—are particularly rich in beneficial compounds, especially polysaccharides and antioxidants. These mushroom extracts showed impressive abilities to fight antibiotic-resistant bacteria and protect cells from oxidative damage, suggesting they could become valuable sources for new medicines and functional foods.

Diversity and Distribution of Colletotrichum Species Causing Anthracnose in China

mycolabadmin

Researchers identified 16 different species of Colletotrichum fungi causing anthracnose (a leaf and branch disease) in plants across five Chinese provinces. They discovered four previously unknown species and clarified the classification of several known species using DNA analysis. The study found that different regions had different predominant fungal species, with walnut being particularly susceptible to specific Colletotrichum species. These findings help understand and manage anthracnose diseases in economically important plants in China.

Phaeohyphomycosis due to Nigrograna chromolaenae in a cardiac transplant patient

mycolabadmin

A 71-year-old heart transplant patient developed a slowly growing bump on his finger caused by a rare fungus called Nigrograna chromolaenae. Doctors initially tried common antifungal medications that didn’t work well, but the patient improved significantly when switched to posaconazole treatment. This is the first documented case of this particular fungus infecting a human, highlighting the importance of accurately identifying fungi to choose the right treatment.

A Case of Pulmonary Infection Due to Magnusiomyces capitatus in a Non-Immunocompromised Patient with Cerebral Palsy

mycolabadmin

A young man with cerebral palsy developed a rare lung infection caused by Magnusiomyces capitatus, a fungus that usually only affects people with weakened immune systems. Doctors diagnosed the infection by analyzing fluid from his lungs and identified the fungus using advanced laboratory techniques. The patient improved after being treated with an antifungal medication called voriconazole. This case highlights that this rare fungal infection can occur in otherwise healthy people, especially those with conditions affecting their ability to clear lung secretions.

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.

Taxonomic revision of Bisifusarium (Nectriaceae)

mycolabadmin

This study provides a comprehensive update on Bisifusarium fungi, a group that includes species used in cheese production and some that can cause human infections. Researchers examined 116 fungal isolates from around the world and identified 25 distinct lineages using DNA analysis. They formally described 8 new species and provided detailed descriptions and photos of previously poorly documented species. This work doubles the known diversity of this fungal genus and will help scientists and medical professionals better identify and understand these fungi.

Current taxonomic status of the cultivable and uncultivable Paracoccidioides species

mycolabadmin

Researchers have clarified the scientific names and classification of five species of fungus that cause disease in humans and dolphins. Some previously proposed species names were found to be invalid because they didn’t follow proper naming rules. The paper recommends that scientists use updated disease names like paracoccidiodomycosis instead of the older term lobomycosis to maintain consistency in medical terminology.
