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.

Pomegranate Woody Mycobiota Associated with Wood Decay

mycolabadmin

Pomegranate trees in Italy are suffering from a wood disease that causes cankers and browning of the wood, leading to plant death and crop loss. Researchers identified multiple fungal species responsible for this disease, with Neofusicoccum parvum and Diaporthe species being the main culprits. Cold winter temperatures appear to weaken trees, making them susceptible to these fungal infections. Using advanced DNA analysis along with traditional methods, scientists confirmed which fungi cause the most damage and how the disease develops.

Electrical integrity and week-long oscillation in fungal mycelia

mycolabadmin

Researchers monitored electrical signals in fungal mycelial networks over 100 days to understand how fungi coordinate their activities across space. When fungi encountered wood to decompose, they generated a clear, directional electrical signal from the wood toward the rest of the mycelium, acting like a biological command center. Most remarkably, after 60 days, the fungi developed a week-long electrical rhythm at the wood site, the longest oscillation ever recorded in fungi, which may help the fungus remember resource locations and coordinate its decomposition activities.

Is Ischnoderma benzoinum a competitor or contributor to Heterobasidion annosum decomposition of pine and spruce wood? A comparison to Phlebiopsis gigantea

mycolabadmin

This research examined how three wood-decomposing fungi interact when competing for the same wood resources. Scientists tested whether Ischnoderma benzoinum helps or hinders the harmful root rot fungus Heterobasidion annosum in pine and spruce forests. They found that the outcome depends on which fungus isolates are involved and which tree species is affected, with some combinations showing strong competition while others showed cooperative decomposition.

Saprotrophic Wood Decay Ability and Plant Cell Wall Degrading Enzyme System of the White Rot Fungus Crucibulum laeve: Secretome, Metabolome and Genome Investigations

mycolabadmin

This study investigates how a forest fungus called Crucibulum laeve breaks down wood and plant material. Using specialized laboratory techniques, researchers found that this fungus uses a unique set of enzymes that work through oxidation (chemical breakdown using oxygen) rather than simple digestion. The fungus is particularly good at degrading birch wood and produces numerous copies of genes for these special enzymes, giving it an advantage in decomposing partially rotted plant material on the forest floor.

First Report of Trametes hirsuta, Causal Agent White Rot in Avocado Trees Grown in the State of Michoacán, México

mycolabadmin

Researchers discovered a wood-destroying fungus called Trametes hirsuta causing serious disease in avocado trees in Mexico’s main avocado-growing region. The fungus attacks tree trunks and branches, causing white rot that can kill trees within 3-5 years. The study confirmed this is a new threat to avocado orchards and suggests controlling it through pruning, chemical fungicides, or biological control methods.

Electrical integrity and week-long oscillation in fungal mycelia

mycolabadmin

Researchers discovered that fungal mycelia (underground networks of fungal threads) use electrical signals to communicate across their bodies when searching for food like wood. When a fungus found a piece of wood to eat, it generated electrical signals that spread throughout its mycelial network, possibly helping coordinate the fungus’s response. Most remarkably, the fungus exhibited a peculiar electrical rhythm at the food location that cycled every week—the longest such pattern ever observed in fungi.

Transcriptomic Insights into the Degradation Mechanisms of Fomitopsis pinicola and Its Host Preference for Coniferous over Broadleaf Deadwood

mycolabadmin

This research examined how a common forest fungus called Fomitopsis pinicola breaks down different types of wood. Scientists found that this fungus much prefers coniferous trees like pine and is much better at degrading them than broadleaf trees like birch. By analyzing which genes the fungus turns on when degrading different woods, they discovered the fungus activates more genes related to breaking down the tough lignin component when working on pine wood, explaining why it naturally chooses conifers in forests.

Taming the Production of Bioluminescent Wood Using the White Rot Fungus Desarmillaria Tabescens

mycolabadmin

Scientists have developed a way to make wood glow in the dark using a special fungus called Desarmillaria tabescens. By carefully controlling moisture levels and giving the fungus time to break down wood components, they created a glowing material that could one day replace electric lights. This bioluminescent wood is completely natural and requires no electricity, offering a sustainable lighting solution for homes and cities.

Microbial decay of wooden structures: actors, activities and means of protection

mycolabadmin

Wood is an increasingly popular sustainable building material, but fungi and bacteria can cause significant damage to wooden structures. This review explains how different types of fungi and bacteria decay wood through various mechanisms, describes advanced DNA methods to identify these microorganisms, and outlines practical strategies to protect wood. By combining proper design, chemical treatments, and wood modification techniques, builders can extend the lifespan of wooden structures while maintaining environmental sustainability.
