Abstract

We surveyed macrofungi biweekly at defined plots from April to December in 2014, in the Mongolian oak-dominant forest, Gwangneung Forest, Pochen-si, Korea, and analyzed a soilhigher fungal diversity during four seasons (represented by April, August, October, and December). Based on morphological observation of collected specimens, the collected macrofungi were classified into 2 phyla 3 classes 7 orders, 14 families, 21 genera, and 33 species (36 specimens). DNA-based community analyses indicated that soil-higher fungi were classified into 2 phyla, 18 classes, 49 orders, 101 families, and 155 genera (83,360 sequence reads), defined herein as 155 genus-level operational taxonomic units (GOTUs). In the present study, we evaluated and discussed the fungal diversity in seasonal dynamics and soil layers based on collected macrofungi and pyrosequencing data while considering environmental parameters (pH, exchangeable K, T-P, NH4+, NO3-, OM, WR, TOC, and T-N). Moreover, principal components analysis (PCA) showed distinct clusters of the GOTU assemblage associated with the seasons.
