Progression of saproxylic fungal communities in fine woody debris in boreal forests of Oulanka, Finland, assessed by DNA metabarcoding

mycolabadmin

Researchers used a novel method called MycoPins—sterilized wooden pins buried in forest soil—combined with DNA analysis to identify and track fungal communities decomposing dead wood in Finnish boreal forests. Over one year, they found 215 fungal species colonizing these pins across three different forest types. Notably, 41 of these species had never been recorded in the region before, showing that DNA-based methods can reveal fungal diversity that traditional observation methods miss.

Twenty-nine new host records of powdery mildew fungi (Erysiphaceae) in Taiwan with an updated checklist

mycolabadmin

Researchers updated Taiwan’s list of powdery mildew fungi, which are harmful plant pathogens affecting crops and trees worldwide. By collecting specimens from various locations and analyzing them using genetic sequencing and microscopy, they identified 29 new host-fungus combinations, with six Erysiphaceae species documented in Taiwan for the first time. The updated checklist now includes approximately 109 powdery mildew species known to affect 246 different host plant species across 75 plant families in Taiwan.

Phylogeny, taxonomy and geographic distribution of novel and known fungi with holoblastic-denticulate conidiogenesis in Rhamphoriales and Pleurotheciales (Sordariomycetes)

mycolabadmin

Researchers have discovered and described four new fungal species that live in decaying wood and soil, particularly in temperate forests. These fungi share a unique way of producing spores (conidiogenesis) that helps scientists classify and understand their relationships. Using genetic sequencing and environmental DNA data from around the world, scientists mapped where these fungi are found and learned that different species prefer different climates. This research improves our understanding of fungal diversity and how these decomposer organisms are distributed globally.

Multigene phylogeny and taxonomy of Dendryphion hydei and Torula hydei spp. nov. from herbaceous litter in northern Thailand

mycolabadmin

Scientists discovered and formally named two new fungal species from dead plant material in northern Thailand. Using both traditional microscopy to examine the fungi’s physical structures and modern DNA analysis, they determined these are previously unknown species within the Torulaceae fungal family. The research helps scientists better understand fungal diversity and how different fungal species are related to each other.

Epidemiological profile of dermatophytes at the parasitology-mycology laboratory at Mohammed VI University Hospital in Oujda

mycolabadmin

This study examined fungal skin infections caused by dermatophytes in a Moroccan hospital over four years, analyzing 950 samples. The researchers found that nail infections (onychomycosis) were most common, particularly in people over 50 years old, while scalp infections mainly affected children. The fungus Trichophyton rubrum was responsible for most infections, though Microsporum canis increasingly caused scalp infections, likely due to increased pet ownership in Morocco. The study emphasizes the importance of proper laboratory testing to identify the specific fungus and choose appropriate treatment.

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.
