Summary Neocatenulostroma germanicum (syn. Catenulostroma germanicum ) , an ascomycetous fungus, is recorded for the first time in Lithuania and the Ukraine. N. germanicum was observed colonizing pine needles and causing needle blight symptoms on Pinus mugo in coastal areas of Lithuania, Pinus nigra subsp. pallasiania in southern areas of the Ukraine and Pinus sylvestris in both coastal and continental areas of Lithuania. N. germanicum was commonly associated with Dothistroma spp. and/or Lecanosticta acicola on needles with symptoms of needle blight, but was also found occurring alone. Phylogenetic analysis, morphological examination and cultural and ecological characterizations of Neocatenulostroma isolates obtained during this study demonstrated that the species belongs to the N. abietis/N. germanicum species complex. Molecular analysis (of ITS , LSU , actin and TEF 1‐α sequences) showed that most isolates were more closely related to the N. germanicum ex‐type. The pathogenicity of one N. germanicum isolate from Lithuania on P. sylvestris was confirmed in an artificial inoculation experiment.
