Mycena haematopus CBHHK189 v1.0
Mycena haematopus

The genome of Mycena haematopus was sequenced as part of the overarching JGI 1000 Fungal Genomes project "Deep Sequencing of Ecologically-relevant Dikarya" (CSP 1974) - and more specifically, as a part of the Mycenaceae sequencing project. This project will examine members of the Mycena genus with respect to evaluate the genomic basis of their different nutritional modes.

The burgundydrop bonnet, or blood-foot mushroom, Mycena haematopus

Mycena haematopus is a member of the galactopoda section of the Mycena family (Maas Geesteranus 1988). The collection for the sequenced culture was collected in Denmark (2015), and the species has been reported from all over Europe and North America (Smith 1936, Maas Geesteranus 1988, Robich 2016, Aronsen & Læssøe 2016). This species is easily recognisable due to its heavy "bleeding" of blood-red latex when its tissue is broken or scratched.

Pileus up to 25-40 mm across, obtusely conical, campanulate to parabolical, somewhat flattening with age, with or without umbo, shallowly sulcate, translucent-striate, densely powdered or pruinose, glabrescent, hygrophanous, dark brown with a faint vinaceous shade at the centre, paler brown with a pinkish shade towards the margin, sometimes stained with purplish spots with age, drying pinkish white, the margin usually crenate. Lamellae 18-25 reaching the stipe, ascending, narrowly to broadly adnate, decurrent with a tooth, becoming dorsally intervenose, whitish to grey, developing more brownish flesh-colour or pale vinaceous, sometimes becoming stained with purplish spots in age; the edge concolorous, sometimes purplish brown to blackish brown. Stipe up to 60 x 2.5 mm, hollow, fragile, straight to curved, equal, terete to compressed, at first densely white-powdered, soon glabrescent, vinaceous red-brown, darker below, exuding a dark red-brown fluid when cut; the base densely covered with white fibrils. Odour indistinctive.1

It is most frequently found on deciduous wood and debris, and occasional to rare on coniferous wood. Growing season is summer to autumn. It is related to M. sanguinolenta, which prefers conifer litter and wood, and M. crocata, which is exclusively found on deciduous litter/debris, both of whom will also be sequenced as part of the Mycenaceae project. While each of them will provide insights about their respective evolution of enzymatic complexes fit for degradation of their respective substrates, their combined information will also elucidate the evolution of adaptive niche differences among closely related species.

This genome was derived from diploid pure culture on MEA agar with ampicilin and benomyl and should be free of xenobiotic contaminations.

Researchers who wish to publish analyses using data from unpublished Mycena genomes 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).
