Karadzic, D. (Sumarski fakultet, Beograd (Yugoslavia))
The pathogenic fungus Lachnellula willkommii, agent of larch canker, was first observed in Serbia (Yugoslavia), on the mountain Kopaonik (locality "Markova stena"). The degree of infection was very high: about 48% of trees had the disease symptoms, and 6% of trees were dry. The apothecia are formed during the summer and usually occur on the dead bark and in the crevices of the canker. In plantations of Scots pine, the pathogenic fungus Gremmeniella abietina was first observed in Serbia. The fruitbodies (pycnidia and apothecia) are formed on stems, shoots, needles, and on Scots pine cone scales.
