Sumario:Background and aims: Thermophilic and thermotolerant fungi occupy a variety of ecological niches. The purpose of this article is to show that these microfungi are able to live even in such harsh conditions of the high Arctic beyond the Arctic Circle. M&M: Rock from coal mine spoil tips were collected and studied using scanning electron microscopy. The method of direct inoculation was employed to isolate microfungi. The isolates were identified using morphological identification and molecular methods. The growth rate of micromycetes was studied depending on temperature. Results: Eight cultures of microfungi belonging to six species that are able to grow at temperatures of 45 °C and above were isolated from coal mine spoil tips. Conclusions: The data obtained indicate the presence of thermophilic and thermotolerant microfungi in the spoil tips of coal mines beyond the Arctic Circle. All the fungi belonged to the order Eurotiales. These microfungi are able to exist in the harshest conditions with several simultaneous adverse factors.
