Carbon dioxide (CO2) is a metabolic byproduct of respiration in fungi (ie, fungi breath oxygen and exhaust carbon dioxide).

CO2 sensitivity Edit

Although all species are sensitive to carbon dioxide throughout their lifecycle, some species react differently to varying concentrations in carbon dioxide.

Antler formationEdit

Some species, such as Grifola frondosa and Ganoderma lucidum, will form antler shaped fruit bodies in increased concentrations of CO2
