Mushrooms are a versatile ingredient in the culinary world, and they come in a wide variety of shapes, sizes, and flavors. When it comes to cooking mushrooms, the question of whether to cook them hot or cold arises. The answer to this question depends on the type of mushroom and the desired outcome.
Temperature plays a crucial role in the cooking process of mushrooms. Cooking them at the right temperature can bring out their unique flavor and texture, while cooking them at the wrong temperature can result in a tough and rubbery texture. Some mushrooms, such as shiitake and oyster, are best cooked hot, while others, like portobello and button mushrooms, are better cooked at a lower temperature.
Fungi, the group of organisms that mushrooms belong to, are highly sensitive to temperature changes. They thrive in cool and damp environments, and their growth is inhibited by high temperatures. This sensitivity to temperature makes it important to choose the right cooking method for mushrooms. In the following section, we will explore the different ways to cook mushrooms and the ideal temperature for each method.
Mushroom Biology and Temperature Needs
Mycelium and Fruiting
Mushrooms are fungi that grow from mycelium, a network of thread-like structures that absorb nutrients from the surrounding environment. Mycelium is responsible for the growth of the fruiting body, which is the visible part of the mushroom that we eat. The fruiting body contains spores, which are released into the environment to start new colonies of mycelium.
The temperature needs of mushrooms depend on the stage of growth. Mycelium grows best at temperatures between 65-75°F (18-24°C), while the fruiting body needs cooler temperatures to properly develop. Research has shown that mushrooms are able to regulate their own temperature, and can be up to 5.9°F (10.6°C) cooler than the surrounding air [1].
Temperature Range for Optimal Growth
Maintaining a consistent temperature is crucial for the growth rate and quality of the mushrooms. Most mushrooms prefer a temperature range between 65-75°F (18-24°C) for optimal growth. However, different species of mushrooms have different temperature requirements. For example, oyster mushrooms grow best at temperatures between 60-70°F (15-21°C) [2].
It is important to note that even small fluctuations in temperature can impact the growth rate and quality of the mushrooms. Therefore, temperature control is essential during all stages of mushroom growth. This can be achieved through the use of a temperature-controlled environment, such as a greenhouse or a grow tent.
In summary, mushrooms have specific temperature needs depending on the stage of growth. Mycelium grows best at temperatures between 65-75°F (18-24°C), while the fruiting body needs cooler temperatures to properly develop. Maintaining a consistent temperature is crucial for the growth rate and quality of the mushrooms, and different species of mushrooms have different temperature requirements.

Mushroom Cultivation Techniques
Substrate and Temperature Control
Mushroom cultivation requires careful attention to substrate and temperature control. Substrate is the material that the mushroom mycelium grows on, and it can be made from a variety of materials such as straw, sawdust, or compost. Temperature control is also crucial for successful mushroom cultivation, as different species of mushrooms have different temperature requirements for growth.
According to Fungi.org, Psilocybe cubensis mushrooms and mycelium are generally the happiest between 22°C – 27°C or 70°F – 80°F. While they will grow in colder temperatures, their growth rates will be far from nominal, and not ideal for cultivation. On the other hand, maintaining a temperature range of 18-22°C (64-72°F) and humidity levels between 80-90% creates an ideal environment for mushroom growth, according to gardeningpleasure.com.
Mushroom cultivators can use thermometers, heating pads, cooling fans, or greenhouses to monitor and adjust temperature levels as needed. It is important to note that different species of mushrooms have different temperature and humidity requirements, so growers should research the specific needs of the mushrooms they are cultivating.
Indoor vs Outdoor Cultivation
Mushroom cultivation can be done indoors or outdoors, and each method has its own advantages and disadvantages. Indoor cultivation allows for greater control over temperature and humidity levels, which can lead to higher yields and better quality mushrooms. However, indoor cultivation requires more equipment and can be more expensive.
Outdoor cultivation, on the other hand, is less expensive and requires less equipment, but it is more susceptible to environmental factors such as temperature, humidity, and pests. Outdoor cultivation also requires more space and is subject to seasonal changes in temperature and weather conditions.
In conclusion, successful mushroom cultivation requires careful attention to substrate and temperature control, as well as consideration of the advantages and disadvantages of indoor vs outdoor cultivation. By understanding the specific needs of the mushrooms being cultivated and using appropriate cultivation techniques, growers can achieve high yields of quality mushrooms.
Environmental Factors Affecting Mushrooms
Mushrooms are sensitive to environmental factors such as humidity, moisture, and temperature. They require specific conditions to grow and thrive. In this section, we will discuss the two most important environmental factors affecting mushrooms: humidity and moisture, and seasonal temperature variations.
Humidity and Moisture
Mushrooms require a high level of humidity to grow. The ideal humidity level for mushroom growth is between 70% to 90%. If the humidity level is too low, the mushrooms will dry out and stop growing. On the other hand, if the humidity level is too high, it can lead to the growth of mold and other harmful bacteria.
Moisture is also an essential factor for mushroom growth. The substrate used for mushroom cultivation should be moist but not wet. If the substrate is too dry, the mushrooms will not be able to absorb enough water, which can lead to stunted growth and poor quality mushrooms.
Seasonal Temperature Variations
Mushrooms are sensitive to temperature variations. Different species of mushrooms have different temperature requirements for growth. However, most mushrooms grow best in temperatures between 55°F to 65°F (13°C to 18°C).
During the winter months, the ambient temperature drops, and the humidity level decreases. This can make it challenging to maintain the ideal temperature and humidity levels required for mushroom growth. In such cases, growers use artificial heating and humidification systems to maintain the ideal conditions.
During the summer months, the ambient temperature rises, and the humidity level increases. This can lead to the growth of harmful bacteria and mold. Growers use ventilation systems to maintain the ideal conditions during the summer months.
In conclusion, mushrooms are sensitive to environmental factors such as humidity, moisture, and temperature. Growers need to maintain the ideal conditions to ensure optimal growth and yield.
Mushroom Species and Their Climate Preferences
Mushrooms are a diverse group of fungi that have varying temperature preferences. Some species thrive in colder environments, while others prefer warmer climates. Understanding these preferences is crucial for successful mushroom cultivation.
Cold-Tolerant Species
Cold-tolerant mushroom species, such as morels and oyster mushrooms, prefer temperatures between 50-60°F (10-16°C). These species can be grown in cooler environments, such as basements or outdoor spaces in the fall or early spring. Oyster mushrooms, in particular, are known for their ability to grow in low temperatures and can even tolerate frost.
Heat-Loving Varieties
Heat-loving mushroom species, such as shiitake and reishi, prefer warmer temperatures between 70-80°F (21-27°C). These species are typically grown indoors or in warmer outdoor environments. Shiitake mushrooms, for example, require a warm and humid environment to grow successfully.
It’s important to note that while some species have specific temperature preferences, many can tolerate a range of temperatures. For example, oyster mushrooms can grow in temperatures ranging from 50-80°F (10-27°C), while shiitake mushrooms can tolerate temperatures as low as 50°F (10°C).
In addition to temperature, humidity is also an important factor in mushroom cultivation. Most species prefer high humidity levels between 80-90%. Maintaining proper temperature and humidity levels is crucial for successful mushroom growth.
Overall, understanding the temperature preferences of different mushroom species is essential for successful cultivation. By providing the right environment, growers can ensure healthy and abundant mushroom crops.
