Brown rot (What types of trees does it affect, substrates, appearance, decayed wood, speed of decay?)

• Affects conifers

• Affects cellulose and hemicellulose substrates

• Looks dry, powdery, brown decay, with cracks and cubes

• Drastically reduces wood strength

• has rapid speed of decay because it is chemically mediated

White rot (What types of trees does it affect, substrates, appearance, decayed wood, speed of decay?)

• Affects conifers and broadleaf trees

• Affects lignin, cellulose, and hemicellulose substrates

• Is fibrous, stringy, is often white, selective delignification (conifers) or simultaneous rot (broadleaf trees)

• Retains strength early on, white rot a portion of it’s structural strength n the early stages of decay

• Has a slow speed of decay (because it is enzymatically mediated)
