Geopyxis carbonaria (Pezizales - Pyrenomataceae) is one of the most abundant postfire discomycetes in boreal forests, hence its common name.
After a boreal forest fire, fruiting bodies (ascocarps) of G. carbonaria disperse their ascospores to the surrounding healthy forests, making the re-establishment of a biotrophic association possible. However, by possessing features such as saprotrophic ability, rapidly germinating ascospores, and adaptations to cope with the postfire conditions (e.g. tolerance to high pH level and low water-holding capacity of the substrate) the fungus may provide an in situ inoculum for the spruce seedlings which revegetate the fires sites.
This species has been recorded in Europe and North America.
