Introduction. People who live or work in buildings damaged by moulds face higher risk to their health. Microscopic fungi spread indoors can cause allergies, toxic reactions, of immune system weakness, and mycoses. The aim of the work was to find out microscopic fungi damaging liv­ing and working premises, to specify their taxonomic dependence and to pres­ent macro- and microscopic peculiarities of most spread micromycetes.
