A study of soil samples was carried out al five contiguous habitats of different vegetation types from the Reserva atural Selva Marginal Punta Lara (Buenos Aires, Argentina): coast, dry forest, floodplain marsh, grassland and marginal forest. Soil samples were processed with a baiting technique, thus producing an inventory of twenty four saprophytic organisms belonging to the Blastocladiomycota, Chytridiomycota and Oomycetes. The frequency analysis showed that all species were of rare occurrence on a macro scale although there were distributional differences between habitats. Cluster analysis showed three groups: (i) the marsh and the grassland, (ii) the dry and the marginal forests and (iii) the coast, which appeared to be the poorest habitat with only three isolations and two taxa recorded.
