ABSTRACT
This study was carried out in order to evaluate soil mycobiota in different soil positions (shoulder, back slope, foot slope) in a dune, located in Restinga da Marambaia, RJ. The studied area of approximately 500 m2 was divided in three parts with vegetation ranging from the shrubs to trees. It was a 50 x 50 m enclosed plot where five 10 cm-deep mini trenches were opened for soil collection. Three composite samples formed by the gathering of five single samples were collected for analysis and characterization of the soil mycobiota. The highest aluminum content and the lowest nutrient content were observed in the foot slope position. The colony unit formation varied from 4.6 x 103 to 9.0 x 104 cuf.g-1. 49 fungi - in a total of 85 isolated, belonging to 13 genders and 32 species - were found. Penicillium, Aspergillus and Trichoderma were the most frequent genders. The highest richness value was observed in the back slope position. Trichoderma pseudokoningi was the most common species found in the areas. This study implies that Restinga da Marambaia presents a great fungal diversity.
