Fig. 1.

Phylogenetic distribution of the 83 dominant fungal phylotypes. Ring 1 indicates the most likely functional guild for each phylotype, inferred by parsing the phylotypes with FUNguild⁷⁸, where brown = saprotroph, yellow = symbiotroph, green = pathotroph. For each phylotype, black squares in Ring 2 and 3 indicate whether there is a representative type strain or isolate match at ≥98% ITS2 gene sequence similarity level, while black squares in Ring 4 highlights the presence of a matching genome at ≥97% similarity threshold. The colouring on the outermost ring matches the preferential environmental distribution for all phylotypes (n = 83), where purple = mesic, yellow = forest, red = drylands. Trem. = Tremellomycetes, Umb. = Umbelopsis, Euro.= Eurotiomycetes. The abundance (%) and richness of the dominant phylotypes in relationship to the non-dominant phylotypes are reported in the pie charts. The nucloetide sequence of the dominant phylotypes is reported in Supplementary Data 1
