Vertical distribution of marine fungi on Rhizophora apiculata at Morib mangrove, Selangor, Malaysia

Studies on the vertical distribution of marine fungi in a Rhizophora apiculata mangrove stand in Morib, Selangor were carried out in June 1993 and June to November 1997. Prop roots, subterranean roots and overhanging branches of R. apiculata were collected from three intertidal levels namely upper (...
