Document Summary
Diagnostic features: accumulation of fungi with orangish-brown cap, produced on the decayed tree trunk. Other information: nearby species were not infected with sapwood rot disease. Control measures: fungicide application and removal of all fungi that grow on the tree trunk or on the ground (the pennsylvania state university, 2011). Disease information: the disease is called sapwood rot due to decay in sapwood part of host. The infection facilitates production of fungi and fungi producing structures such as mycelia and rhizomorphs. Severe infection causes death of bark and eventually death of tree (isa, 2009). Pathogen information: flammunila velutipes survives in mycelium of the dead tree when there are warm weather conditions present. After that, basidiospores are transported to infect other host. Infection causes mycelium production on the lowest part of the tree trunk. Eventually, fungi inhibit the production of rhizomorphs, root-like structures that function as fungi producing bodies (isa, 2009). Host information: flammunila velutipes infects many poplar species.
