The genome of Mycena leptocephala 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 nitrous bonnet, Mycena leptocephala

Mycena leptocephala is a member of the large Fragilipedes section (Maas Geesteranus 1988, Aronsen and Læssøe 2016). It can generally be recognised by having a translucent-striated pileus with brownish colours and a white/whitish margin, a similarly coloured stipe usually with white fibrils, and a nitrous smell. It grows on a wide variety of substrates, including grass and woody debris, and it has been recorded from a multitude of places in both hemispheres. The collection for this sequencing was found in Bolterdalen at Svalbard on the 11th of August 2018. Besides its versatile ecology, this species was chosen for genomic sequencing because it could be found in the Arctic where the extreme environmental conditions may drive unusual ecology patterns and genome sizes.

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 Researchers who wish to use data from unpublished Mycena genomes for publication are respectfully required to contact the PI and JGI to avoid potential conflicts on data use and coordinate other publications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).
