|| Hymenoscyphus fraxineus|
||Genus name: membrane with a stalk-like elongation.
Species epithet: of ash tree.
|Alternative Species Name(s):||Chalara fraxinea, which is the name of the anamorphic stage. Hymenoscyphus pseudoalbidus.|
||Europe. The fungus is probably also found in Asia, but is there described under the name Lambertella albida. In Asia, however, ash trees appear to be resistant to the disease.
|Reproduction:||The sexual reproduction occurs in small, white mushroom-like fruiting bodies, which are formed during the late summer on the stems from last year's fallen leaves. The spores are then spread with the wind to the ash leaves, leaf stalks and annual shoots. There, the spores form the so-called appressors (attack organs), which enter the leavesand passes into the asexual stage where the hyphae grow out of the petioles (leaf stalks) and further into the shoots where the inner bark is killed.|

|Ash tree (Fraxinus excelsior)||Ash dieback, chalara or chalara dieback||The leaves get brown necrosis, the leaf buds dry out and form dead shoots, which causes the growth to become bush-like.|
