Examined 25 species of cryptogams - wetlands species (moss form Sphagnum genus and examined representatives of Pteridophyta) and species creating so-called submerse meadows (examined representatives of Charophyta and moss from Fontinalis genus) showed that the other cryptogams - fungi and fungus - like organisms interactions are threefold. First, the most abundant group of cryptogams (15 species) are species (all representatives of Charophyta and 2 species of moss from Sphagnum genus) which inhibit the growth of fungi and fungus - like organisms. The second group (7 species) are species conducive to growth (these are examined species of Hepaticae and all species of Musci, excluding the species from Sphagnum genus). The last one, the least numerous group including 3 examined species of Pteridophyta is neutral for fungi and fungus - like organisms growth - those species neither are conducive nor inhibit the growth of species from fungi and fungus - like organisms. As it is well known, algae secrete extracellularly different organic substances; one of them are being a medium for different organisms and other inhibit the growth of many organisms. The representatives of Charophyta excrete to the environment so-called sulphur compounds, for example allin and its derivatives, which inhibit the growth of many organisms. Probably those substances inhibit also the growth of some species of fungi and fungus - like organisms. Considering high percentage of garlic in submerse meadows in ponds and lakes it should be thought that they may notably create also the dynamics of fungi and fungus-like organisms in their habitats.
