Mushrooms, including Coprinellus micaceus and species from the genus Cantharellus, are known to use the process of evapotranspiration to maintain internal temperatures below ambient temperatures. This hypothermic behavior is enhanced by the many thin gills (lamellae) on the fungi's caps, with substantial surface area contributing to capacity for evaporation. Examining fungal thermoregulation mechanisms, Radames Cordéro et al. determined that molds and yeasts also engage in evaporative cooling to facilitate hypothermia and suggest that, lacking features analogous to lamellae, these unicellular fungi aggregate into colonies to derive the benefit of greater surface area.

Although a certain thermoregulation process has been observed in colonies of unicellular fungi, it has yet to be observed at the individual organism level.

A recent analysis of specimens of Coprinellus micaceus and species from the genus Cantharellus substantiated the findings of earlier studies of thermoregulation mechanisms in several types of fungi.

A study of a fungal thermoregulation mechanism determined that it is used more efficiently by molds and yeasts than by mushrooms and other multicellular fungi due to variances in colony size.

Despite significant differences in their biological structures, mushrooms, molds, and yeasts have been observed to utilize the same thermoregulation process to achieve a particular effect.
