Mushrooms are a unique type of fungus that exhibit a hypothermic nature, meaning they are often colder than the surrounding air temperature. This characteristic has sparked interest in their potential for thermal regulation and cooling applications. While the thermal biology of fungi remains relatively unexplored, research suggests that mushrooms achieve their colder temperatures through evaporative cooling, similar to plants. This discovery has implications for understanding the role of fungi in global ecology and predicting the impact of climate change. Aside from their temperature quirks, mushrooms are also known for their temperature sensitivity during cultivation and processing. Growers must maintain specific temperature and humidity ranges to ensure optimal mushroom growth, as even slight fluctuations can impact their quality. Similarly, when preparing mushroom-infused teas or beverages, temperature plays a critical role in unlocking the desired compounds and potency. Whether in nature, the laboratory, or our kitchens, mushrooms seem to have a complex relationship with temperature, leaving us curious to explore further whether we are hot or cold on these fascinating fungi.

Mushrooms are colder than their surroundings due to evaporation
Mushrooms are known to maintain a colder temperature than their surroundings, a phenomenon that has been confirmed by researchers using infrared thermography. This cooling effect is a result of evaporation, specifically evaporative cooling or evapotranspiration. The process involves the evaporation of water from the mushroom's structure, leading to a decrease in temperature.
Evaporative cooling in mushrooms was first observed in laboratory-grown specimens, where thermocouple detectors were inserted into mushroom caps to measure their temperature. Subsequent studies provided additional quantitative data on mushroom evapotranspiration, with researchers developing mathematical models to link mushroom water loss with ambient humidity and temperature.
The cooling nature of mushrooms has also been observed in wild mushrooms in their natural habitat. Molecular biologists at Johns Hopkins Bloomberg School of Public Health, in collaboration with a colleague from the University of Puerto Rico, confirmed that mushrooms are indeed cooler than the air around them. On average, mushrooms were found to be 2.9 ± 1.4 °C colder than the surrounding air, with some specimens ranging from 1.4 to 5.9 °C colder.
The mechanism of evaporative cooling in mushrooms is believed to be an ancient evolutionary adaptation for thermoregulation. This process is not unique to mushrooms but is also observed in other fungi, including yeast and mold colonies. The condensation of water droplets above these colonies contributes to their relatively colder temperatures. Furthermore, the cooling effect of mushrooms is more pronounced in humid environments compared to dry conditions, further supporting the role of evaporation in their temperature regulation.

The ideal temperature range for growing mushrooms is 65-75 °F
Mushrooms are known for their hypothermic nature, with studies finding that they are often colder than the surrounding air. This is due to the evaporation of water from the fungi, akin to sweating in humans. However, when it comes to growing mushrooms, the ideal temperature range is between 65-75 °F. Maintaining a consistent temperature within this range is crucial for the growth and quality of the mushrooms. Deviations from this range can impact the growth rate, with lower temperatures slowing down or stopping the growth of the mycelium, which is the vegetative part of the mushroom.
To achieve the ideal temperature range, mushroom growers employ various tools and techniques. One commonly used tool is a thermometer or temperature sensor, which helps monitor the temperature of the growing medium and the surrounding environment. This allows growers to make adjustments as needed to maintain the desired temperature. Another useful tool is a heating pad or mat, which can be placed under the growing area to provide additional heat if needed.
In addition to heating options, cooling methods are also essential to prevent the growing area from becoming too warm. A cooling fan can be used to increase air circulation and quickly lower the temperature. This helps prevent the mushrooms from overheating and becoming damaged. For more control over the growing environment, some growers use a greenhouse or grow tent, which provides an enclosed space that can be easily regulated using a heating or cooling system.
While the ideal temperature range for mushroom growth is generally between 65-75 °F, it's important to note that the temperature preference can vary slightly depending on the species of mushroom. Additionally, other factors, such as humidity, also play a crucial role in successful mushroom growth. High humidity levels, typically around 85-95% relative humidity, are necessary for proper mushroom growth. Monitoring and controlling both temperature and humidity are key to creating the ideal environment for mushrooms to thrive.

Mushroom tea is best brewed at 85-90 °C
Mushrooms are known for their hypothermic nature, with studies showing that they are often colder than the surrounding air. This is due to the evaporation of water from the fungi, similar to sweating in animals. However, when it comes to consuming mushrooms, the preparation methods can vary, and temperature plays a crucial role in unlocking their benefits.
Mushroom tea, for example, is a popular way to consume mushrooms, and the brewing temperature directly impacts its effectiveness. While mushroom extracts are generally stable and can be used in hot or cold teas without losing their benefits, the ideal brewing temperature for mushroom tea is between 85-90 °C. Brewing at this temperature unlocks the active compounds in the mushrooms, enhancing the potency and flavor of the tea.
Loose-leaf or bagged teas made from dried mushrooms or mushroom blends are recommended to be steeped at 85-90 °C for optimal efficacy. This temperature range ensures that the sensitive compounds in the mushrooms are not damaged, resulting in a more effective and flavorful tea. Brewing at temperatures above 90 °C should be avoided as it may compromise the benefits of the tea.
It is important to note that the brewing temperature may vary slightly depending on the type of mushroom and the specific compounds being targeted. For example, psilocybin, a compound present in some mushrooms, starts to degrade above 70 °C, so a lower temperature is recommended for teas containing this compound. Additionally, the ideal temperature range for growing mushrooms is between 65-75 °F, and maintaining a consistent temperature is crucial for their growth.

Fungi make up 2% of Earth's biomass
Mushrooms are known to be colder than the surrounding air, a phenomenon that has been observed in laboratory settings. This is due to a process called evaporative cooling, which is also seen in mould and yeast colonies. Interestingly, this characteristic of being colder than their surroundings may not be unique to mushrooms, as some data suggests that this could be a general trait of the entire fungal kingdom. Indeed, fungi make up approximately 2% of Earth's biomass, and their evaporative cooling may contribute to cooler temperatures in their local environments.
Fungi, including mushrooms, play a critical role in maintaining Earth's ecology. They help break down decaying organic matter and provide nutrients for new growth. Fungi are also a source of food, medicine, and various biomaterials for humans. However, some fungi can be harmful to plants and animals, causing significant agricultural and public health issues.
The thermal biology of fungi remains relatively unexplored, and further research is needed to understand the temperature regulation mechanisms of these organisms. Nonetheless, the ability of fungi to maintain colder temperatures than their surroundings has potential applications in passive indoor air conditioning.
While humans have a significant impact on the Earth, our biomass is relatively small. We make up just 0.06 gigatonnes of carbon, which is a tiny fraction of the total biomass on Earth. In contrast, plants represent the majority of biomass, accounting for 82.4% or 450 gigatonnes of carbon. Fungi, at 2%, contribute significantly more biomass than humans, highlighting the importance of these organisms in the Earth's ecosystem.
