The genome of Mycena filopes 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 iodine bonnet, Mycena filopes

Mycena filopes is a member of the section Filipedes (Maas Gesteranus 1988). It is known from Europe (Aronsen and Læssøe 2016). It is most commonly found on needle (Picea) litter, but can be seen on all types of litter and woody debris.

M. filopes is closely related to Mycena metata, 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. It 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 is sequenced in tandem with M. metata 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Researchers who wish to use data from unpublished Mycena genomes for publication are respectfully required to contact the PI and JGI to avoid potential conflicts on data use and coordinate other publications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).
