Leccinum scabrum (Bull.) Gray (Boletaceae) is an edible mycorrhizal species with potential application interest due to its food and medicinal properties. A field investigation carried out during summer in the Białowieża Primeval Forest, located along the border between Belarus and Poland allowed to collect samples for chemical composition analysis...

... A large number of the commonly called mushrooms, which are sporomata produced during the sexual stage of the life cycle of various filamentous fungal species, are known as a source of abundant nutrients and bioactive components (Chaturvedi et al. 2018). From the nutritional point of view, edible mushrooms provide a variety of beneficial components, including proteins, carbohydrates, vitamins, and minerals, while showing a low-fat content (Fogarasi et al. 2020;Gargano et al. 2024). For instance, accumulating evidence shows that mushrooms are a natural source of ergosterol (pro-vitamin D) and B vitamins (Kurtzman 2005). ...
We tested the effect of entomogenous fungi isolated from the Coleoptera species Ophrida xanthospilota and of the medicinal mushroom Lentinula edodes on the lifespan of Drosophila melanogaster. All the four analyzed strains of entomogenous fungi showed pathogenicity to D. melanogaster by causing 100% mortality of fruit flies within 20 culture days. The shortest lifespan was recorded in flies treated with Fusarium verticillioides (15 days). On the contrary, L. edodes showed a remarkable lifespan-extending effect on the model organism, with fruit fly individuals surviving for 55 culture days. Fungal growth was microscopically observed on the bodies of dead fruit flies treated with the four entomogenous fungal species, confirming that the tested fungi were responsible for the mortality of the model insects. Our findings showed that the four fungal species previously found on the body of Coleoptera individuals are entomopathogenic and could be exploited in agriculture applications for the biocontrol of noxious pests. The significant lifespan extending effect on Drosophila produced by the analyzed L. edodes strain could represent very important experimental evidence of the anti-aging and lifespan prolonging effects of this medicinal mushroom species.
