Abstract

First proof of Lophodermium cedrinum in Germany - cause of a needle-cast of Cedrus spp.

Abstract

In spring 2014 a needle disease on young trees of Cedrus atlantica, C. deodara as well as C. libani was observed in a tree nursery in Lower Saxony, Germany. The disease is characterized by yellow-brown needle discolorization, followed by needle cast. The hypodermataceous ascomycete Lophodermium cedrinum Maire was revealed as causal pathogen. Disease symptoms and morphological criteria of the fungus are described, supplemented with illustrations. The needle parasite was reported for Northern Africa and Asia until now. Therefore this is the first report on this fungus in Germany or rather Europe. Aspects of phytosanitary measures are discussed.
