According to Wikipedia, “The fungus can be readily transported from the outdoors, and grow indoors using building material or accumulated soil to obtain nutrients for growth.” And, once spores are carried indoors, they easily become established thanks to their low moisture needs: “Penicillium growth can still occur indoors even if the relative humidity is low, as long as there is sufficient moisture available on a given surface.” This is particularly likely to happen in areas where rainfall is heavy, such as the coastal United States or the UK; a British study found that Penicillium spores were so prevalent in the indoor air of residential properties they sampled that spore levels indoors actually exceeded outdoor levels by 16 percent. Stocks grown on rice were stored at room temperature (RT) in the dark.
