"Wood and Tree Fungi" provides an up-to-date overview of the various wood and tree fungi that damage trees, lumber, and timber, with special focus given to identification, prevention, and remediation techniques. First, the fundamentals of cytology and morphology, growth and reproduction, and formal genetics are addressed. Causative factors are then analyzed, followed by descriptions of interactions like antagonism, succession, and mycorrhiza. The more practical section describes tree damages caused by viruses and bacteria on the xylem of wood, the discoloration caused by molds and fungi, and preservation methods. The habitats of wood fungi are discussed as well as tree care. Important tree pathogens and wood decay fungi are characterized for prevention and identification. The final section focuses on the positive effects of wood-inhabiting microorganisms, covering past and classical methods like myco-wood, mushroom cultivation, biological pulping, and "palo podrido", as well as recent biotechnological processes.
