The genome of Mycena floridula 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.

Mycena floridula

Mycena floridula is a member of the Adonideae section (Maas Gesteranus 1988). It is uncertain whether it is conspecific with Mycena adonis (= Atheniella adonis) (Redhead et al. 2012). As our collection showed the distinctive yellowing of the pileus characteristic of M. floridula as opposed to the absence of this character in the most reddish-pinkish colouration of M. adonis, we kept it here under the name M. floridula. This species is only known from Northern and Central Europe, and the collection for the culture was sampled on spruce (Picea abies) litter in the coniferous forest on Vettakollåsen in Southeast Norway.

The Adonideae section, including Mycena floridula, has been shown to be more closely related to Marasmiaceae, and is thus not closely related to Mycena sensu stricto (Moncalvo et al. 2002). In our sequencing effort on Mycenaceae, we included M. floridula as one representative of Mycena sensu lato for comparison with the other sensu stricto species, hoping to elucidate how the many striking similarities in morphology and ecology may have evolved convergently.

This genome was derived from dikaryotic (diploid) pure culture.

Researchers who wish to use data from unpublished Mycena genomes for publication are respectfully required to contact the PI and JGI to avoid potential conflicts on data use and coordinate other publications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