In this paper, we present a spectroscopic study to differentiate the macroscopic mushrooms: Russula Congoanan (Rc), Lactifluus
gymnocarpoides (Lg) and Amanita amasasiensis (Aa). The analysis of the
spectra, acquired by absorption spectrophotometry in the UV-visible range of the extracts obtained by hydration of dry mushroom fragments, shows that
they are distinguished by their absorption peaks. The characteristics such as position, intensity and width at half height change according to the species of mushroom studied. Thus, extracts of the species Russula Congoanan (Rc),
Lactifluus gymnocarpoides (Lg) and Amanita amasasiensis (Aa) show peaks at wavelengths of 257nm, 222nm and 242nm respectively, where the
electronic properties are attributed to bond transitions pi-pi* related to polyphenols.
