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).
