Heterobasidion annosum sensu lato is a species complex comprising five species that are widely distributed in coniferous forests of the Northern Hemisphere and are each characterized by a distinct host preference. More than 1,700 papers have been published on these fungi in the past four decades, making them perhaps the most widely studied forest fungi. Heterobasidion species are at different levels on the saprotroph-necrotroph gradient, and the same individual can switch from one mode to the other. This offers a unique opportunity to study how genomic structure, gene expression, and genetic trade-offs may all interact with environmental factors to determine the life mode of the organism. The abilities of Heterobasidion spp. to infect stumps as saprotrophs and to spread to neighboring trees as pathogens have resulted in significant damages to timber production in managed forests. This review focuses on the current knowledge of the biology, ecology, evolution, and management of these species and is based on classical and modern studies.
