Abundance of Ascomycotina was studied from soil in coastal sand dunes of Orissa for a period of two years covering three distinct seasons. A total of 16 species of fungi belonging to 9 genera were enumerated of which site without vegetation surface soil had a share of 8 genera and 10 sp. while sub surface soil produced 7 genera and 10 species. Site with ＂Anacardium＂ plantation; the surface soil contributed 5 genera and 7 species while sub surface soil contributed 5 genera and 9 species. The diversity index varies from 3.6 to 3.74 (Shannon) and 0.32 to 0.35 (Simpson). Similarity index shows that barren sand dune is less akin to sand dune with monoculture plantation of ＂Anacardium＂. Despite poor fungal population and nutrient composition in site without vegetation in comparison to soil with Anacardium plantation, more species were recorded from barren coastal sand dunes, which may be due to less competition with other fungi.
