The genome of Mycena metata was sequenced as part of the Mycenaceae sequencing project and the overarching JGI 1000 Fungal Genomes project “Deep Sequencing of Ecologically-relevant Dikarya“ (CSP 1974).This project will examine members of the Mycena genus to evaluate the genomic basis of their different nutritional modes.
The frost bonnet, Mycena metata
Mycena metata is a member of the section
Filipedes (Maas Geesteranus 1988). It is known from Europe
(Aronsen and Læssøe 2016). It is most commonly found
on needle (Picea) litter, but can be seen on several types
of litter and woody debris. The collection from which the culture
was generated was collected in Bromme Plantage, Zealand, Denmark
the 27th of October 2015.
M. metata is closely related to Mycena filopes,
and both species are very common, but they have different (though
overlapping) phenology. M. filopes is most abundant from
summer to early autumn and ceases completely to appear when it
starts freezing, while M. metata has its peak abundance
later in the autumn and is able to survive and grow into the early
winter season. M. metata appears to even thrive on the
first nights of freezing temperatures, where the forest floor can
be full of newly grown M. metata fruitbodies. M.
filopes and M. metata are sequenced in tandem in
order to study the genetic adaptation to freezing
temperatures.
This genome was derived from dikaryotic (diploid) pure culture on
MEA agar with ampicilin and benomyl and should be free of
xenobiotic contaminations. Researchers who wish to use data from
unpublished Mycena genomes for publication are
respectfully required to contact the PI and JGI to avoid potential
conflicts on data use and coordinate other publications with the
Mycena master paper(s).
