Organic Nitrogen Supplementation Increases Vegetative and Reproductive Biomass in a Versatile White Rot Fungus

mycolabadmin

Researchers studied how adding nitrogen from plant litter affects the growth and mushroom production of a wood-rotting fungus called Cyclocybe aegerita. They found that adding the organic compound adenosine—which naturally occurs in plant litter—significantly boosted both the fungus’s vegetative growth and the production of mushrooms. The results suggest that fungi living in wood benefit from being able to absorb nitrogen-rich compounds from nearby plant material, which improves their ability to grow and reproduce.

Characterization of Self-Growing Biomaterials Made of Fungal Mycelium and Various Lignocellulose-Containing Ingredients

mycolabadmin

Scientists developed environmentally-friendly foam-like materials by growing mushroom mycelium (the root-like network of fungi) on agricultural waste like hemp and sawdust. These natural composites are strong, biodegradable, and can be used for packaging or insulation instead of plastic foam. However, they absorb water easily and can develop mold if exposed to moisture, so they need protective coatings for some applications.

Mushroom By-Products as a Source of Growth Stimulation and Biochemical Composition Added-Value of Pleurotus ostreatus, Cyclocybe cylindracea, and Lentinula edodes

Researchers discovered that leftover mushroom materials from commercial cultivation can be recycled to boost the growth of edible mushroom mycelium. When mushroom waste extracts were added to growing media, they enhanced mycelial growth by up to 89.5% and increased beneficial compounds like chitin and proteins. This finding suggests a promising way to reduce mushroom farming waste while simultaneously improving the nutritional quality of cultivated mushrooms.

Biologically active secondary metabolites from white-rot fungi

mycolabadmin

White-rot fungi are special mushrooms that can break down wood and produce unique chemical compounds with amazing health benefits. These compounds have been found to fight cancer, kill harmful bacteria, reduce inflammation, and protect nerve cells. Scientists are excited about using these natural fungal compounds to create new medicines and treat various diseases in the future.

Phylogenetic Analysis and Nutritional Evaluation of Laetiporus Species in Korea

mycolabadmin

Researchers in Korea identified that ‘chicken of the woods’ mushrooms growing in the region are actually two specific species: Laetiporus versisporus and Laetiporus cremeiporus, not the species previously thought. These mushrooms are nutritionally impressive, containing substantial protein (9-18% depending on species) and high levels of beneficial β-glucans (15-35%), making them promising candidates as sustainable meat alternatives and functional food ingredients.

Lomasomes and Other Fungal Plasma Membrane Macroinvaginations Have a Tubular and Lamellar Genesis

mycolabadmin

Scientists studied mushroom cells to understand structures called lomasomes that form at the cell membrane surface. Using advanced microscopy techniques, they discovered these structures are made of tiny tubes and layers that can fold and swell into different shapes. These findings help explain how fungal cells that decompose wood organize their membranes and may be involved in how cells take in materials from their surroundings.

Four new species of Marasmius subgenus Globulares (Marasmiaceae, Agaricales) from subtropical regions of China

mycolabadmin

Scientists discovered four previously unknown species of small mushrooms called Marasmius in subtropical forests of China. These tiny fungi were identified through detailed examination of their physical characteristics and DNA analysis. The new species have distinctive features like different colored caps, spore sizes, and microscopic structures. This discovery adds to our understanding of fungal biodiversity in Chinese subtropical regions.

Draft Genome Sequence of the Coprinoid Mushroom Coprinopsis strossmayeri

mycolabadmin

Scientists sequenced the complete genetic blueprint of Coprinopsis strossmayeri, a mushroom that lives in dung. By analyzing its genome, they discovered the mushroom produces multiple types of chemical compounds with antimicrobial properties that could be useful for developing new medicines. The research highlights how fungi living in competitive environments like dung have evolved to produce substances that could benefit human health through pharmaceutical applications.

Omics approaches to investigate pre-symbiotic responses of the mycorrhizal fungus Tulasnella sp. SV6 to the orchid host Serapias vomeracea

mycolabadmin

This research explores how orchid-associated fungi sense and respond to their host plants before they even make physical contact. Scientists used advanced molecular techniques to track changes in gene expression and chemical composition in Tulasnella fungal cells when exposed to orchid plants. The fungi showed significant metabolic preparation, increasing production of proteins and cellular membrane components, suggesting they are actively preparing for symbiosis. This study reveals that plant-fungus interactions begin through long-distance chemical communication before the organisms ever physically meet.

Holarctic Species in the Pluteus podospileus Clade: Description of Six New Species and Reassessment of Old Names

mycolabadmin

Scientists have discovered and formally identified six new species of mushrooms in the Pluteus podospileus group that was previously thought to be a single variable species across the Northern Hemisphere. Using DNA analysis combined with traditional microscopic examination, researchers found that what was once considered one widespread species is actually multiple distinct species with different geographic distributions in Europe, Asia, and North America. The study also resurrected an old, forgotten species name and clarified the relationships between various populations of these small brown mushrooms that grow on decaying wood in forests.
