Abstract：In order to explore the status of macrofungal resources,this study randomly sampled macrofungi.By combin-ing morphological identification and ITS sequence analysis,56 strains were identified from 255 samples.These strains be-longed to 1 phylum,1 class,4 orders,13 families,and 30 genera,respectively.The results showed that 5 families were predominant,namely Agaricaceae,Boletaceae,Russulaceae,Entolomataceae,and Amanitaceae.These 5 families account-ed for 73.21%of the total number of strains and 38.46%of the total number of families.There were 5 dominant genera,which were Agaricus,Amanita,Leucoagaricus,Lactarius,and Boletus.These 5 genera accounted for 42.86%of the total number of strains and 16.67%of the total number of genera.The macrofungi of Jianmen Shu Road are classified as north-ern temperate distribution types by floristic geographical composition,accounting for 76.79%of the total strains.This study represents the first identification of macrofungal species from the Jianmen Shu Road,revealing 23 edible fungi,1 rare edible-medicinal fungus,7 toxic fungi,and 5 industrial fungi.Among these are nutrient-rich Russula vinosobrunneo-la,Ganoderma leucocontextum with medicinal value,toxic Amanita cyanochlorinosma,and Trametes duplexa with indus-trial value.These fungi not only play vital roles in ecosystems but also offer significant development potential for medi-cine,food,and biotechnology.The study constructed a macrofungal resource library for Jianmen Shu Road,identifying 56 strains across 30 genera.Based on application value classifications,including edible and rare edible-medicinal fungi,the study revealed the potential value of regional fungi in drug development and functional food innovation.The ITS se-quence identification data and germplasm resource information provide direct data support for the sustainable utilization and biodiversity conservation of macrofungi in this region.
