In the “1KFG: Deep Sequencing of Ecologically-relevant Dikarya” project (CSP1974), we aim to sequence additional sampling of genomic diversity within keystone lineages of plant-interacting fungi and saprophytic fungi that are of special ecological importance for understanding terrestrial ecosystems. In addition, comparative genome analysis with saprotrophic, mycorrhizal and pathogenic fungi will provide new insights into the specific and conserved adaptations associated with each fungal lifestyle.

Cerinomyces crustulinus OMC1686

Cerinomyces crustulinus is a corticioid basidiomycete, forming thin, smooth, effused fruiting bodies on dead wood. It is one of the few such species in the class Dacrymycetes, where most of the species are jelly fungi. Cerinomyces crustulinus was described from France growing on beech, but most of the collections of this species derive from conifers (e.g. Eriksson & Ryvarden 1973). This species is rather rare.

Type of rot of Cerinomyces has not been studied; presumably they are brown-rotters. Cerinomyces crustulinus is the type species of the genus Cerinomyces in the family Cerinomycetaceae, which is an early diverging lineage within the class Dacrymycetes (Shirouzu et al. 2013). Since Dacrymycetes is the earliest diverging known extant lineage of wood decomposing basidiomycetes (Nagy et al. 2016), the genome of this species is of interest in understanding evolution of fungal wood decomposition ability. Along with Dacrymyces tortus, these are the first species from the family Cerinomycetaceae to have their genomes sequenced.

The genome sequence was produced from a polysporic culture that derives from central Finland, where it grew on a bole of pine (Pinus sylvestris).
