Alnus glutinosa, Bergen NH, Uilenvanger: under the microscope the strong branching of the hairs is apparent
Alnus glutinosa, France, Haute Savoie, Rhône Alpes, St. Nicolas de Véroce, 1175 m: very aberrant gall, possibly a different species; © Arnold Grosscurt

Aceria, Eriophyes, Phytoptus, brevitarsus.
