Fomitopsis pinicola (Sw.) P. Karst is a brown rot Basidiomycete species commonly collected on dead conifer trees or occasionally live trees in boreal forest of the Northern hemisphere. The basidiocarps of the species are perennial and persist for many years producing a new layer of hymenophore every growing season. The role of Fomitopsis pinicola in the conifer forests is very important as the species is one of the most prominent wood decayers in these ecosystems and thus play important role in the carbon cycle. The species is characterized by brown rot biochemistry where the cellulose and hemicellulose are utilized by the fungus leaving behind the lignin. This results in a brown appearance of the degraded wood tissue, which crumbles into cubical, fragile pieces. Fomitopsis pinicola is placed in the clade of Antrodia along with other species of the genus. Antrodia clade is a major clade in the Polyporales, which consists of brown rotters. Postia placenta, which has been sequenced already by the Joint Genome Institute, is also placed in the Antrodia clade. The genome sequence of Fomitopsis pinicola will increase our knowledge on the brown rot biochemistry for the genus and it will create new opportunities for comparative studies on the wood degradation biochemistry with other important brown rot species, that have been sequenced or they will be sequenced, such as Postia placenta, Gloeophyllum trabeum and Serpula lacrymans.
