The mycoflora of needles, shoots and branches of Picea abies of different ages, with particular reference to older trees suffering from spruce dieback



The mycoflora of needles, shoots and branches of Picea abies of different ages, with particular reference to older trees suffering from spruce dieback



Forstwissenschaftliches Centralblatt 103(6): 349-360



Studies on 80-yr-old Norway spruce trees in W. Germany showed that trees classed as 'declining' had higher proportions of damaged needles and dead shoots, twigs and branches than trees classed as 'healthy'. However, no clear differences could be found in the species of fungi found in healthy and declining trees. The fungi most often isolated from the needles were Rhizosphaera kalkhoffii, Tympanis sp. and Lophodermium piceae, but they were not the primary cause of Norway spruce dieback.
