Clavicorona pyxidata represent the first sequenced coral fungus, i.e. a species with a branched, coral-like fruiting body morphology. The coralloid fruiting body morphology is widespread in the mushroom-forming fungi and has been hypothesized to be an important stepping-stone in the evolution of mushrooms and the emergence of more complex structures, such as those found in important crop and medicinal mushroom species in the Agaricales. By sequencing the genome of Clavicorona pyxidata, this and other hypotheses about fruiting body evolution in mushrooms become testable. The key interest in Clavicorona pyxidata is its potential to uncover the factors related to mushroom formation. Identifying the genetic bases of mushroom formation and its evolutionary origins is central to mushroom biotechnology and to the improvement of commercial mushroom production. The genus Clavicorona belongs to the Russulales, a diverse order of mainly ectomycorrhizal agarics (Russula & Lactarius). Within the order, Clavicorona represent and early-diverging lineage with significant wood-decay capability. This makes it possible to explore the enzymatic wood-decay systems and gene families in greater detail in the Russulales, previously represented only by a single or two species.
