A total of 68 different species of microscopic fungi have been isolated and identified from two different ecological niches of Georgia: wet-subtropical (Poti region) and subalpine (Kazbegi region) soil-climatic zones. Extremophiles of 11 genera, belonging to classes Ascomycetes, Zygomycetes, and Deuteromycetes were identified, and the frequency of occurrence of a particular genus and regularity of their diffusion was determined. Screening of the isolated fungi was performed under extreme conditions of cultivation (low and high temperatures, very low and high pH medium), and 33 extremophiles were revealed, 13 by temperature and 20 by pH.
