Identification of the Armillariaspecies in selected coniferous stands (Scots pine stands,
Norway spruce stands and fir stands) was the aim of the work carried out on the basis of
mating tests and consideration of macroscopic traits of fruit bodies. One species of Armillaria
[A. ostoyae(Romagnesi) Herink] was found in Scots pine stands, three species [A. ostoyae, A.
cepistipesVelenovský and A. borealisMarxmüller et Korhonen] were found in Norway spruce
stands and two species [A. ostoyaeand A. cepistipes] were found in fir stands
