Osmophilous fungi in the salt marshes of Kuwait.

During an investigation of the mycoflora inhabiting saline soils in Kuwait, special attention was focused on osmophilous fungi. A total of 101 species belonging to 46 genera were encountered from 40 soil samples collected from salt marshes using Czapek's agar supplemented with 40% sucrose. Soil samples were collected from different habitats at different distances from the water edge. Soils near to the water edge were poor in their fungal content, while those taken from areas covered by Juncus arabicus contained highest fungal populations. The recorded genera were classified as follows: 7 were of high frequency of occurrence, 8 moderate, 17 low, and 13 were rare. The order of dominance was Aspergillus, Alternaria, Penicillium, Cephalosporium, Fusarium, Stachybotrys, and Drechslera. Comparison between our results and those in other studies showed that there is no fungal flora characteristic of saline soils.
