Abstract：Toinvestigate thespeciesdiversityandresourcevalueofwildmacrofungiinZhangguangcai Mountains， province，filltheresearch gap inthisregion，and promote theconservationandutilzationofmacrofungalgermplasmresources，412macrofungal specimenswerecollected fromthe Zhangguangcai Mountainsusingrandomized transectand line-intercept methods.Through integrated morphologicalandmolecularidentification，combined withresource evaluationandfloristic geographical componentanalysis.161 macrofungal species were identified，which belong to2 phyla，6classes，18orders，55families，and93genera.Thedominantfamilies（ ⩾10 species）were Polyporaceae（23 species， 14.29% ）andHymenochaetaceae（11 species， 6.83% ）.Fivedominant genera ⩾5 species）wereidentified：Trametes （8 species， 4.97% ），followed byPleurotusandRussula（7 specieseach， 4.35% each）.Resource evaluation classified 12 edible species，37medicinalspecies，17dual-purpose（edible-medicinal）species，and5toxicspecies.Intermsofgeoraphical composition of genera， cosmopolitan genera predominated（63 genera， 67.74% ），followed by north temperate（20 genera）andpantropical elements（1O genera）.This studyprovides fundamental data for macrofungalconservation and sustainable utilization in Zhangguangcai Mountains.

大型真菌通常是指肉眼可见、徒手可摘的真菌，主要为担子菌门（Basidiomycota）、少数为子囊菌门（Ascomycota）真菌，该类真菌具有重要的经济价值，在生态系统中对促进植物生长、维持生态系统的稳定及物质循环和能量流动发挥不可替代的作用，也在一定程度上影响森林和人类的健康。（剩余9733字）
