Short Communication: Microfungal diversity on leaves of Eusideroxylon zwageri, a threatened plant species in Sarawak, Northern Borneo

Abstract

Adebola AL, Sepiah M, Bolhassan MH, Wan Zamir M. 2015. Microfungal diversity on leaves of Eusideroxylon zwageri, a
threatened plant species in Sarawak, Northern Borneo. Biodiversitas 16: 264-268. A survey of the microfungal communities on green
leaves and leaf litters of an endangered plant species, Eusideroxylon zwageri Teijsm. & Binn. (belian) was carried out for the first time.
A total of 200 leaf segments were plated on both water agar and malt extract agar. 74 fungal species were identified from both leaf types
with more fungal taxa found on the green leaves, with a Shannon diversity index of 3.85 compared to that on litters, 2.63 and the
similarity between the microfungal communities on both leaf types was low with a Bray-Curtis similarity index of 0.366. The most
dominant species on both leaf types includes Aphanocladium areanarum, Trichoderma koningii, Nectria sp., Chalara pteridina,
Hyphomycetes sp.3, hyaline Mycelia sterilia, Circinotrichum sp., Phoma sp., Acremonium macroclavatum, Chaetopsina sp., Physarum
sp., Beltrania rhombica and Colletotrichum acutatum.
