Abstract: Biodiversity and ecology of higher filamentous fungi on Nypa fruticans in Brunei were examined during 1999. Forty-six taxa were recorded including 33 ascomycetes and 13 anamorphic taxa in 25 genera. Linocarpon was the most speciose genus (6 species) followed by Aniptodera and Astrosphaeriella (4 each). The mycota mostly comprised typical marine species (e.g. Aniptodera, Lulworthia, Savoryella). Linocarpon appendiculatum (13%) and L. bipolaris (13%) were most frequently recorded, while Oxydothis nypae (9%), Astrosphaeriella striatispora (6.4%), Trichocladium nypae (6.4%) and Linocarpon nypae (5.4%) were also common. Most of the fungi (50%) were rare in their occurrence. More diversity was found on fronds than on leaves. Linocarpon appendiculatum, L. bipolaris, Neolinocarpon globosicarpum and Oxydothis nypae were more frequently recorded on fronds than other fungi, while Linocarpon bipolaris (13.5%), Astrosphaeriella striatispora (12.2%), Trichocladium nypae (8.1%) and Linocarpon appendiculatum (8.1%) were more frequently recorded on leaves. Examination of vertical distribution of fungi showed that the submerged parts have a rich fungal diversity followed by intertidal parts and finally the aerial parts.
