AbstrakTaman Nasional Ujung Kulon (TNUK) adalah salah satu kawasan lindung terletak di Kabupaten Pandeglang, Banten. Di kawasan ini terletak Desa Ujung Jaya. Formasi hutan di kawasan ini sangat bervariasi, dengan keanekaragaman plasma nutfah yang cukup tinggi, sehingga sangat memungkinkan ditemukan jamur makro. Penelitian ini bertujuan mendapatkan data jenis-jenis jamur makro dan data potensi baik sebagai bahan pangan, bahan obat, dan sebagai mikoriza. Metode yang digunakan dalam penelitian ini adalah metode jalur, yaitu dengan mengamati dan mencatat sampel di sepanjang jalur penelitian, yang meliputi kawasan hutan sekitar permukiman, kawasan mangrove, dan kawasan permukiman penduduk. Hasil penelitian didapatkan sebanyak 98 spesies jamur makro di TNUK, dengan sebaran sebanyak 56 spesies di kawasan permukiman, 31 spesies di kawasan hutan, dan 32 spesies di kawasan mangrove. Jamur makro yang ditemukan didominasi phylum Basidiomycota 92 spesies, sementara phylum Ascomycota hanya 4 spesies dan sisanya 2 spesies dari kelompok jamur lendir (phylum Myxomycota). Sebanyak 28 spesies sebagai bahan pangan, 56 spesies sebagai bahan obat, dan 5 spesies sebagai mikoriza.Abstract Ujung Kulon National Park (TNUK) is a protected area located in Pandeglang Regency, Banten. Located in this area is Ujung Jaya village. Forest formations in this region is very varied, with a fairly high diversity of germplasm so that it is possible to find macro fungi. The purpose of this study was to obtain data on macro fungi and potential data as food ingredients, as medicinal ingredients, and as mycorrhizae. The method used in this study is the path method, which is by observing and recording samples along the research path, which includes forest areas around settlements, mangrove areas, and residential areas. From the results, 98 species of macro fungi were found in Ujung Kulon National Park, from which 56 species were found in residential areas, 31 species in forest areas and 32 species in the mangrove area. Macro fungi found were dominated by phylum Basidiomycota, as many as 92 species, the rest were Ascomycota phylum as many as 4 species and phylum Myxomycota (slime mold), as many as 2 species. A total of 28 species as food ingredients, 56 species as medicinal ingredients, and 5 species as mycorrhizae.
