Table 1 The results of ITS sequencing for the two groups of samples. Most of the fungi identified in the samples belonged to the phylum Ascomycota, class Sordariomycetes, order Sordariales, family Bolbitiaceae, and genus Agrocybe. At the species level, the highest frequency OTU1 matched four different fungal ITS regions: Agrocybe pediades, Serendipita indica, Humicola grisea, and Rhizopus arrhizus
