Table 1: _Cont._The entries were distributed in 39 orders. Eurotiales and Hypocreales were the most represented ones, together accounting for more than half of total fungal diversity. Pleosporales, Capnodiales, Sordariales, and Chateothyriales were also well represented orders within Ascomycota. Basidiomycota accounted for a maximum of around 6% of all taxa, with Agaricales, Helotiales, and Saccharomyces being the most abundant ones accordingly. Mucorales was the most abundant order within the phylum Mucoromycota. The accuracy in taxa determination varied among the different papers analyzed, with many entries identified only at genus level. In fact, a total of 107 out of 378 entries (28.3%) referred to genera not determined at the species level, and it was not possible to quantify the number of possible different species belonging to these genera within different papers. A total of 61 genera (35.2%) were represented by a single species. _Aspergillus_ and _Penicillium_ (order Eurotiales) were the most frequently recorded genera and were represented by a greater number of species, 40 and 46, respectively, present in 44 (59.4%) and 32 (43.2%) sites, which increased to 54 (73%) and 51 (68.9%) when those sites where the genera were reported as undetermined at the species level were also considered. Their contribution to the total number of records was significant, with 219 (18.1%) and 154 (12.7%) records, respectively. Other genera frequently recorded were _Alternaria_ and _Fusarium_ with seven species each; _Acremonium_, _Cladosporium_, and _Trichoderma_ with six species; _Curvularia_ and _Talaromyces_ with five species; and _Chatonium_ with four species.
