First, at all sites in this study, the total number of isolates in spring us greater than that of summer. Spring weather is windy and dusty. Dust is considered a fungal spore binding agent and wind plays a role in airflow. In addition, ascomycete spores tend to be released with a decrease in relative humidity. These factors ensure that the spores get around more easily and consistently in spring than in summer. During summer, there may be relatively fewer spores in the air owing to inhibition of the spore dispersal by rainfall and greater wind speed compared to that in spring. Second, because the dominant species in summer are basidiomycetes, whereas the dominant apecies in spring were ascomycetes, it can be inferred that basidiomycetes prefer the summer season (i.e. a hot and humid climate). In other words, ascomycetes are likely to live comfortably under conditions of cooler temperatures and lower humidity. The present results demonstrated that seasonal variation can influence the pattern of fungal diversity, in line with some other studies.
