Abstract

The parasitic and saprophytic mycoflora was inventoried on three species in the fam. Cupressaaceae (Cupressus sempervirens, Chamaecyparis lawsoniana and Juniperus virginiana) in Serbia and Montenegro. The greatest number of fungi was recorded on eastern red cedar, but they were mainly the parasites of weakness or saprophytes. The greatest damage on cypress is caused by the pathogenic fungus Seiridium cardinale - agent of bark necrosis and canker. Sphaeropsis sapinea, the pathogen of many coniferous species, was identified on all three hosts on which it does not cause great harm. The study of the morphological characteristics of the fungus on these host plants and the comparative analysis with the morphological characteristics of the same fungus on Pinus spp. shows a difference between them. The study of S. sapinea pathogenicity by artificial inoculations of Austrian pine seedlings in the controlled conditions shows that the isolate of the fungus from cypress can cause infection of uninjured P. nigra shoots.
