The occurrence of fungi in tidal salt marshes in the south west Netherlands follows the same general pattern that has been found elsewhere. In the reclaimed saltings, there is a shift in emphasis from the tidal to a more general soil mycoflora. The balance between the occurrence of Dendryphiella salina and Gliocladium roseum is influenced by the level of salinity in the soil, and D. salina can be used as an indicator of residual salt, or of seepage of seawater through the enclosing dyke. Preliminary physiological studies indicate that increasing salinity levels adversely affect growth and cellulose- and starch-decomposition by G. roseum. D. salina may need salt before cellulose-decomposition occurs. D. salina is reported from an inland saline soil in England [UK], where it was associated with the roots of Spergularia marina. It should be regarded as a halophyte rather than a strictly marine species.
