Although Armillaria borealis is one of the closest relatives of the aggressive root rot
pathogen A. ostoyae, little is known about its ecology. In central and northern Europe, A …

Root and butt rot fungi are important agents of disturbance in forest ecosystems worldwide
and they can also cause significant economic losses. The basidiomycete genus Armillaria is …

Incidence of Armillaria root disease and the population structure of associated Armillaria
spp. were studied in 5-17-year-old Scots pine plantations in west-central Poland. Two …

The basidiomycetes Armillaria cepistipes and Armillaria ostoyae frequently occur in the
same forest stand. In this study, we determined the virulence of 20 isolates of A. cepistipes …

In managed spruce forests, Armillaria cepistipes and A. ostoyae are efficient stump
colonizers and may compete for these resources when they co‐occur at the same site. The …

The frequency of Armillaria species in precommercial thinning stumps and the interaction at
root contacts between Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) crop trees and …

Pathogenicity of four Armillaria species (A. ostoyae, A. mellea, A. gallica and A. tabescens)
was investigated on seedlings and young trees of Quercus cerris, Q. frainetto, Q. ilex, Q …

The process of lesion formation and host response to natural infection by Armillaria ostoyae
were studied in the roots of western larch (Larix occidentalis) and Douglas‐fir (Pseudotsuga …

Distribution, host preference and pathogenicity of Japanese Armillaria species on conifers
were investigated on the basis of field collections of 65 isolates. We identified seven …

Abstract Information about the entry of Armillaria into first‐rotation pine and spruce stands
was obtained by searching for infected stumps, rhizomorph systems or trees that had been …
