Fuckel (1870) Phycoascus A.Møller (1901) Pyronema is a genus of cup fungi in the family Pyronemataceae.

Pyronema are found fruiting exclusively on recently burned or heat-sterilized substrates.

When grown in a laboratory setting on agar plates, P. domesticum produces sclerotia, whereas P. omphalodes does not.

[4] Pyronema are known to dominate the soil fungal community after fire,[5] and P. domesticum has been shown to metabolize charcoal.

[10] In 1889, Pier Andrea Saccardo circumscribed the species P. domesticum, directly building from the work of James Sowerby.
