Succession of fungi on wood of <i>Avicennia alba</i> and <i>A</i>. <i>lanata</i> in Singapore

Abstract

Randomly collected mangrove wood and wood blocks of Avicennia alba and Avicennia lanata submerged for 60 weeks in Mandai mangrove, Singapore, were investigated for marine fungi. Very frequent species on the random samples were Halosarpheia retorquens and Lignincola laevis and on the submerged wood blocks were Didymosphaeria enalia, Lignincola laevis, Lulworthia sp. 1, Aigialus parvus, Aniptodera marina, Halocyphina villosa, and Ascomycete No. 25. The fungi growing on the wood blocks showed a pattern of succession, with L. laevis as an early colonizer, D. enalia and Lulworthia sp. 1 intermediate colonizers, and A. parvus a late colonizer. The variations in the results obtained from the two sampling methods are also discussed.
