Most fungi have the function of breaking down complex organic molecules, enabling the supply of nutrients to the soil through the process of cycling and fertilization. This paper aimed to analyze the richness, frequency, constancy and similarity among decomposing fungi on the litter of three endemic trees in three areas of the Atlantic Forest in southern Bahia. Decaying leaves were collected from December 2007 to June 2008, washed, placed in wet chambers and incubated at room temperature. Fifty-two fungal species belonging to 39 genera were found. The richness of each area was the following: Parque Estadual Serra do Conduru (78,8%), Ecoparque (71.2%) and Reserva Capitão (61.5%). In relation to plants, the richness of Harleyodendron unifoliolatum Cowan was 75.0%, Manilkara maxima Pennington 57.7% and Parinari alvimii Prance 42.3%. There was similarity between plants and between areas. The frequency of most fungi was sporadic. This pioneer work on these trees of the Atlantic Forest of southern Bahia contributes to the knowledge of the anamorphic fungi existing in this biologically rich biome.
