Forest Fungi: Biodiversity, Conservation, Mycoforestry and Biotechnology explores sustainable option aspects of forest fungal research, from the selection of hosting plants, isolation, identification, fermentation, identification of secondary metabolites, omics-tools for better understanding the plant–fungus Interactions. Forests are the world’s greatest repository of terrestrial biomass, soil carbon and biodiversity. They provide a variety of provisioning, supporting, regulatory and cultural ecosystem services, which are crucial for the survival of human beings. Fungi play key roles in forest ecosystems as mutualists, saprobes and pathogens.
