The raw ITS1 amplicon reads of 16 metabarcoding libraries  constructed from the DNA extracts of 280 samples
A total of 16 metabarcoding libraries were constructed from the DNA extracts of 280 samples, each containing ITS1 sequences from 15 to 30 macrofungal samples. Amplicon libraries were constructed using combinations of 1530 uniquely tagged primers designed to target the ITS1 region, with the modified reverse primer ITS2ngs (5-xTTYRCKRCGTTCTTCATCG-3) and modified forward primer ITS1catta (5-xACCWGCGGARGGATCATTA-3).
