Culturable fungi from 28 fungal communities were isolated from soil, rhizosphere and thick (1 cm diam.) roots of living beech ( Fagus sylvatica ) trees and their stumps 1–3 years after felling. All fungi were morphotyped and identified morphologically. The frequency of fungi was 2–5× greater in stumps than in living trees. The diversity of fungi was similar in living trees and stumps. The majority of fungal species that occurred at greater frequency on/in roots of stumps reduced the growth of Armillaria ostoyae and to a smaller extent of A. gallica rhizomorphs in a soil substrate in vitro. It is suggested that the mycobiota of roots may constrain the colonization of F. sylvatica by A. ostoyae rather than by A. gallica . The significance of these findings in the epidemiology of Armillaria in beech forests is discussed.
