Abstract
The distribution of soil microfungi in the successive ecological zones of 8 dune systems on the British coast are recorded. A relatively rich and active fungal population was found in the dune xerosere, but it contained few species which appeared to be confined to the dune habitat. The acid and alkaline dune mycofloras were distinct from one another. A succession of species on a macro-scale, comparable with that of higher plants, was found to occur across the dune systems from the pioneer communities of the foreshore to the climax communities of the fixed dunes. A marked vertical development of the fungal population accompanied the horizontal succession, culminating in a stratified microfungal profile.
