Mushrooms, the fruiting body of mycelium, were previously noticed to be colder than surrounding air through evaporative cooling. Here, we confirm those observations using infrared thermography and report that this hypothermic state is also observed in mold and yeast colonies. The relatively colder temperature of yeasts and molds is also mediated via evaporative cooling and associated with the accumulation of condensed water droplets on plate lids above colonies. The colonies appear coldest at their center and the surrounding agar appears warmest near the colony edges. The analysis of cultivated\n                    <jats:italic>Pleurotus ostreatus<\/jats:italic>\n                    mushrooms revealed that the hypothermic feature of mushrooms can be observed throughout the whole fruiting process and at the level of mycelium. The mushroom\u2019s hymenium was coldest, and different areas of the mushroom appear to dissipate heat differently. We also constructed a mushroom-based air-cooling prototype system capable of passively reducing the temperature of a semiclosed compartment by approximately 10\u00a0\u00b0C in 25 min. These findings suggest that the fungal kingdom is characteristically cold. Since fungi make up approximately 2% of Earth\u2019s biomass, their evapotranspiration may contribute to cooler temperatures in local environments.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2221996120","type":"journal-article","created":{"date-parts":[[2023,5,2]],"date-time":"2023-05-02T13:33:59Z","timestamp":1683034439000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":27,"title":["The hypothermic nature of fungi"],"prefix":"10.1073","volume":"120","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3026-7094","authenticated-orcid":false,"given":"Radames J.
