Ekspresowa Analiza Zagrożenia Agrofagiem: Entoleuca mammata

The occurrence of the species has been reported in Germany and Ukraine, which have weather conditions similar to those of Poland. Entoleuca mammata is a fungus that negatively affects the growth of infested plants and can eventually lead to the death of already dying or diseased host trees. The main host plants are, in Europe, the native species Populus tremula (especially its mountain breed) and Populus tremuloides, which has been introduced to Europe in a hybrid form. The pathogen has the ability to initiate infection only on living but damaged trees and does not occur when the tree is healthy or already dead. E. mammata infects trees throughout the United States, but the greatest problems with the aforementioned pathogen have been recorded in states: Arkansas, North Texas, Oklahoma and the Mountain West. E. mammata is a secondary agent: a primary agent, such as drought or physical damage, usually causes tree death prior to infection with the pathogen.
