Description of the gall

edit

The ascomycete induces a gall that distorts the leaves of alder. The leaves are slightly thickened, brittle and incurved with blister-like growth on both sides, which can increase the size of an infected leaf to twice the normal size. Later the leaf tissue becomes pale and thin with a whitish bloom when the asci develop.[3][4] Species infected include common alder (Alnus glutinosa), grey alder (Alnus incana) and Alnus x pubescens.[1]
