Pyronema domesticum is a species of fungi in the genus Pyronema and the family Pyronemataceae. P. domesticum is a pyrophilous fungi, meaning that it appears in areas that have recently burned. A 2021 study using P. domesticum samples isolated from fruiting bodies of the fungus in the aftermath of the 2013 Rim Fire in California's Stanislaus National Forest found that P. domesticum and the other Pyronema species P. omphalodes likely play a critical role in the post-wildfire succession process through mineralization of carbon converting pyrolyzed organic matter (essentially charcoal) into liberated carbon, returning it to the bioavailable carbon pool.

P. domesticum is a small cup-shaped fungus, orange to pink in hue. It is able to grow rapidly in a culture, where it can form sclerotia. This ability is one of several traits that distinguishes P. domesticum from P. omphalodes.

"Fruiting bodies of the genus Pyronema are among the first macrofungi to emerge from burned soil, doing so within weeks to months after fire" "Pyronema species strongly dominate soil fungal communities within weeks to months after a fire."

For a long time the source of the carbon pool that fuels the rapid population of Pyronema species (including P. domesticum) after fires was not known: researchers suspected it could be either necromass or...
