Trametes ljubarskyi

Trametes ljubarskyi is a wood-decay fungus belonging to the Polyporaceae family. It acts as a primary pathogen that triggers internal stem rot in various deciduous tree species, significantly affecting their long-term health and structural integrity.

This fungus primarily targets broad-leaved trees, including species such as linden, oak, and maple. The infection typically initiates through wounds in the bark, branch stubs, or frost cracks, providing a gateway for the fungal mycelium to colonize the internal woody tissue.

The primary symptom of infection is the presence of characteristic fruit bodies on the trunk surface. Inside, the fungus causes widespread white-rot decay, making the timber brittle and prone to breakage, which alters the physical density of the infected wood.

Development is favored by high humidity levels and ambient temperatures consistent with forest environments. The pathogen disseminates via airborne spores, which land on exposed wood surfaces, allowing for continuous transmission across forest stands.

The economic and ecological impact is significant due to wood devaluation and increased risk of windthrow. Preventive management strategies focus on removing infected trees, maintaining forest hygiene, and applying protective coatings to pruning wounds to prevent secondary fungal infections.
