In the wake of severe climatic extremes during recent years, several new invasive foliage fungi of pines have been reported in Estonia. In this paper the peculiarities of the fast dissemination process, particularly from south to north of two quarantined species, Mycosphaerella pini and M. dearnessii, but also of Diplodia pinea and Cyclaneusma minus on different host species are described. These species were known as destructive pathogens in several countries and continents. By today, the range of M. pini has already reached northern Finland. In its dissemination process we could follow, with the half-year steps, colonization of Estonia from south to north. Some micromorphological features of these alien species were investigated. Hypothetical risk for pine forests was shortly introduced.
