Except that in general most mushrooms produce more CO2 than then consume. In fact, they’ve been researched as a possible additional variable to the CO2 budget equation: https://phys.org/news/2016-01-mushrooms-contribute-global.html https://phys.org/news/2016-01-mushrooms-contribute-global.ht.... I doubt that radiation-loving mushrooms are edible, and if they produce CO2 rather than scrub it, I can’t consider them to be part of the life-support system.
