**3. Conclusions**

The mycorrhizal fungi are distinguished by their living in different environments, including tropical rainforest and sandy desert ones. Many factors that affect the effectiveness of mycorrhiza, as well as the processes of sporulation formation, and the way they coexist with mycoflora or other soil revivals, root colonization, have been studied. We find ourselves in an urgent need to understand these stages of the presence of fungi as we approach the practical aspect of these fungi. Therefore, it is customary to express the presence of fungi with a term called dispersal. With regard to this process of such fungi, studies indicated that they were present in different continents before the flood and drought occurred. Since that time, there are many factors that limit the existence and effectiveness of mycorrhiza, and the most important of which are environmental factors and other biological factors (**Figure 1**).
