From 1991 to 1994 the development of the wood-destroying mycoflora in an old beech stand, thrown by hurricane in 1990, has been investigated. The appearance and succession of the most important fungi on damaged trees, fallen trunks, broken twigs and wooden debris are described in detail and connections with the degree of wood-decomposition are established. With a strong predominance of white-rot fungi, the number of fructifying species increased from 46 in 1991 to 80 in 1994. The initial association on hardly decomposed wood is classified as Trametetum hirsutae Jahn, the later association on distinctly rotten trunks as Trametetum versicoloris Ricek; the characteristic Trametes-species of these associations showed the strongest basidiocarp biomass production of all white-rot fungi in 1992 and 1994, respectively. In the case of several common wood rotters a positive correlation between high basidiocarp productivity and well advanced mycelial extension within the fallen trunks could be demonstrated.
