A survey of fungi from leaf litter at Bach Ma National Park in Viet Nam was initiated. Using surface disinfection and moist chamber with single spore isolation methods, 102 isolates were obtained and of those, 70 isolates were selected for further morphological study. | Journal of Science and Technology 55 (1A) (2017) 37-44 DOI: LEAF LITTER FUNGI ISOLATED IN BACH MA NATIONAL PARK, VIET NAM Le Thi Hoang Yen1, *, Shigeki Inaba2, Yasuhisa Tsurumi2, Nguyễn Thị Hồng Nhung1, Duong Van Hop1, Katsuhiko Ando2 1 Institute of Microbiology and Biotechnology, Vietnam National University, E2, 144 Xuan Thuy, Cau Giay, Ha Noi, Vie Nnam 2 National Institute of Technology and Evaluation, 2-5-8, Kazusakamatari, Kisarazu, Chiba 292-0818, Japan * Email: yenlth@ Received: 30 October 2016; Accepted for publication: 30 May 2017 ABSTRACT A survey of fungi from leaf litter at Bach Ma National Park in Viet Nam was initiated. Using surface disinfection and moist chamber with single spore isolation methods, 102 isolates were obtained and of those, 70 isolates were selected for further morphological study. They belong to 5 classes, 9 orders, 14 families, 33 genera, and 51 species. Among them, Ceratosporella deviata, Lateriramulosa sp., Isthmolongispora ampuliformis, Polylobatispora quinquecornuta, Scolecobasidium tricladiatum, Triglyphiuma labamense, Tricladiella pulvialis, Tripospermum myrti, Triscelophorus sp., Varicosporium elodeaea are newly recorded in Viet Nam. Keywords: Bach Ma, Hyphomycetes, leaf litter, taxonomy. 1. INTRODUCTION Litter decomposition plays an important role in nutrient recycling of forest ecosystems. Animals, bacteria and fungi living in soil are main decomposers. Fungi can decompose plant derived lignin-rich polymers because they are capable of breaking down lignin [1]. Previous studies have investigated fungal diversity in leaf litter in Japan [2], China [3], India [4, 5, 6], Thailand [7, 8], Australia [9] but not yet in Viet Nam. The tropical forests in Viet Nam are characterized by high plant diversity [10] so high fungal diversity is expected in leaf litter. The aim of this study is to shed light on recording the list of fungi on leaf litter collected at Bach Ma National Park in Viet .
