Geographical distribution of Montagnula species with known ITS sequence data. a the map summarizes data from the GlobalFungi database (shown by circles). Each circle symbolizes a unique sample, with each color representing the specific biome from which it has been collected b the distribution of Montagnula sequences as a percentage of total abundance across different biomes c the distribution of Montagnula sequences as a percentage of total abundance across different continents. See Suppl. material 1 for primary data.
