Abstract |
Fungal succession and community development has been studied by direct observation for twenty-four months on stems of Phragmites australis in a brackish tidal marsh of the river Scheldt (The Netherlands). In total 49 taxa were found of which 26 taxa (53%) were ascomycetes, 16 taxa (33%) coelomycetes, four taxa (8%) hyphomycetes and only three taxa (6%) basidiomycetes. Fungal sporulation on standing stems started only after a minimum of three months in a standing dead position and showed different fungal assemblages along the vertical axis of the shoots. Cluster analysis and detrended correspondence analysis showed that all investigated microhabitats (middle canopy, basal canopy and litter layer) showed a different species composition that changed during decay. This successional sporulation was described by a three-staged pattern in each microhabitat. For all of the different microhabitats and for the groups recognized by cluster analysis, indicator taxa were pointed. Gradient analysis indicated that cellulose is the controlling factor for fungal sporulation on the stems. |
