Resumen: It is known that many soil fungi synthesize brown, large aromatic polymers (fungal melanins), chemically related to soil humic acids (Martin and Haider, 1971; Schnitzer and Neyroud, 1975). Since the chemical constituents (or at least, their degradation products) and the physicochemical properties of fungal melanins are comparable to those of humic acids, it is possible that fungal metabolism may represent an important source of constituents for humus formation. Production of humic acid-like compounds by Ulocladium Preuss was reported by Almendros et al. (1985). The alkali-soluble melanin of Ulocladium atrum Preuss was extracted together with a green pigment having similar properties to the Pg fraction found by Kumada and Sato (1962) in soil humic acids, and of a fungal origin confirmed by Kumada and Hurst (1967). This species also produced a significant proportion of a soluble polysaccharide (Martínez et al., 1984), and is an interesting organism for studies of synthesis and transformation of soil organic matter.
