Common split gill
Schizophyllum commune
What is the Common split gill (Schizophyllum commune)?
Schizophyllum commune is a widespread fungus found on every continent except Antarctica. It causes white rot on various hardwood trees, including sickly and dead wood, as well as cut timber. Infected plants may display symptoms such as decayed wood, softening of the affected areas, and white or grayish fungal growth on the surface. The fungus can form sessile brackets or circular fans with split gills underneath. It has also been known to cause rare human mycosis, primarily in immunocompromised individuals, with instances of growth in the oral cavity and sinuses.
How does the Common split gill (Schizophyllum commune) occur?
It reproduces through the production and dispersal of spores. The spores are formed on the surface of the split gills underneath the fruiting bodies. When conditions are favorable, the spores are released into the surrounding environment. The spores can be dispersed by wind, water, or other means and can potentially land on suitable substrates. If the spores germinate and find suitable conditions, they can develop into mycelium, which grows and eventually forms new fruiting bodies, continuing the reproductive cycle of the fungus.
Symptoms
1 - Effects on Plants
Schizophyllum commune causes a white rot in hardwood trees, leading to the decay of the wood. Infected plants may experience structural weakness and deterioration over time.
2 - Effects on Soil
As a saprophytic fungus, Schizophyllum commune plays a role in the decomposition of organic matter, including wood. This contributes to nutrient cycling in the soil and the release of essential elements for other organisms.
3 - Impacts on Environment
• Schizophyllum commune enhances ecosystem functioning by decomposing dead wood and recycling nutrients. • It can supports biodiversity by providing habitat and food sources for various organisms. • Additionally, It influences carbon cycling through the breakdown of organic carbon in dead wood.
Solutions
1 - Preventive Measures
• Maintain overall plant health through proper nutrition, watering, and sunlight to enhance plant resistance against fungal infections. • Regularly inspect plants for signs of infection and promptly prune or remove infected branches or wood to prevent the spread of the fungus. • Clean Garden tools and equipment to avoid spreading the fungus to healthy plants.
2 - Environmental Management
• Avoid overwatering and ensure proper drainage to minimize excess moisture, as Schizophyllum commune thrives in damp environments. • Provide adequate spacing between plants to promote airflow and reduce humidity, creating less favorable conditions for fungal growth. • Explore the use of beneficial fungi or bacteria that can compete with or suppress Schizophyllum commune. Consult with experts for suitable biological control options.
3 - Treatment Options
• In severe cases, apply suitable fungicides as recommended by professionals to control the spread of Schizophyllum commune. • Enhance air circulation around plants to facilitate faster drying of foliage and wood, creating less favorable conditions for fungal growth. • Remove and destroy severely infected plant material, including fallen branches or logs, to prevent further spread of the fungus.
