FUNGAL COMMUNITIES IN ATTACHED ASH BRANCHES

摘要: Summary Attached dead and partly living ash branches of (Fraxinus excelsior) were cut from mature trees the three-dimensional structure their decay communities analyzed. The characterized by three Ascomycotina, seven Basidiomycotina two Deuteromycotina, which varied in ecological roles. Ascomycotina Daldinia concentrica (Bolt: Fr.) Ces. & DeNot. Hypoxylon rubiginosum Pers.: Fr. pioneers growing or recently wood but causing only slow decay. D. is very combative was apparently often able to persist until well decayed. Peniophora limitata (Fr.) Cooke also probably a pioneer tended be found mainly middle terminal regions, as did quercina on few occasions that latter found. Both P. caused extensive white rot. Exidia thuretiana fruiting bark not isolated appeared cause cambial death. An unidentified ascomycete small superficial regions associated with death wounds. lycii (Pers.) Hohn Litsch violaceolivida secondary invaders usually distal subject desiccation. Radulomyces confluens M. Christ similar positions quercina; its role completely clear it acting colonizer. Mycoacia uda Donk once where replacing other species. In addition Phomopsis platanoidis Died, sterile sp., number occasions, former resulted little decay, although decayed wood.
