Trametopsis cervina (Schwein.) Tomšovský is a basidiomycete that produces annual, pileate or effused-reflexed (rarely resupinate) basidiocarps on numerous hardwoods (but predominantly on Fagus sylvatica in Central Europe), and is associated with a white rot. This fungus is separate from the species of the genus Trametes by molecular analysis and some remarkable morphological characters such as dimitic hyphal system and irregular pores of the hymenophore. Molecular analyses include this species in the phlebioid clade, in which (together with the core polyporoid clade where the genus Trametes is included) many white rot species are nested. Thus, T. cervina is related to Phanerochaete chrysosporium, Phlebia radiata, Bjerkandera adusta (whose genomes are sequenced) and Irpex lacteus, in which the production of different enzymes involved in lignin degradation (LiP, MnP, VP and laccases) has been demonstrated. However, T. cervina produces a unique type of LiP differing from those of the above species in the presence of a catalytic tyrosine residue (instead of the conserved catalytic tryptophan). Therefore, the genome sequence of T. cervina will increase our knowledge of ligninolityc machinery within phlebioid clade, including the evolution/diversification of ligninolytic peroxidases, and it will be a good species for comparative genome studies with other already sequenced species.
