This genome was sequenced as part of the JGI CSP "1000 Fungal Genomes – Deep Sequencing of Ecologically-relevant Dikarya" project. Within the framework of this project, we are sequencing keystone lineages of saprophytic, mycorrhizal, and endophytic fungi that are of special ecological importance. Dozens of sequenced species were harvested from Long Term Observatories to serve as the foundation for a reference database for metagenomics of fungi and for a comprehensive survey of the soil fungal metatranscriptome.

Dacrymyces fennicus OMC1656

Dacrymyces fennicus is a poorly known species of brown-rot jelly fungi in the order Dacrymycetales, class Dacrymycetes. It belongs to the family Dacrymycetaceae (Shirouzu et al. 2013) like species of Calocera and Dacryopinax, for which genome sequences are also available (see Calocera cornea, Calocera viscosa, and Dacryopinax primogenitus). Dacrymyces fennicus is a relatively common species in North Europe, inhabiting decaying pine wood in dry places. Its fruiting bodies are small, brownish pustules that resemble a lot a better known but unrelated species, Dacrymyes tortus.

Dacrymycetes are the earliest diverging extant lineage of wood-decaying basidiomycetes (Nagy et al. 2016). It would appear that this lineage has developed its wood-decay capability independently from the rest of basidiomycetes. By comparing their wood-decay related proteins to other wood-decay basidiomycetes we hope to gain insight into mechanisms and origins of wood-decay ability. This Dacrymyces genome is also useful in revising taxonomic classification of the Dacrymycetes. It is still unclear to how many families and orders this class should be divided, and even more cumbersome is the genus classification within the Dacrymycetaceae.

The genome strain was collected from the Finnish south coast on a decaying, uprooted pine tree (Pinus sylvestris).
