The VOCs produced by the Albonectria rigidiuscula fungus in different conditions were obtained by headspace-solid phase microextraction (HS-SPME) and analyzed by gas chromatography-mass spectrometry (GC-MS). Fourty-four VOCs were identified in different culture media and incubation periods. The highest production of VOCs occurred in solid rice medium and 14 days of incubation. The compounds 3-methylbutan-1-ol, 2-methylbutan-1-ol, γ-muurolene and nerolidol acetate were produced by A. rigidiuscula in all culture conditions. γ-Muurolene was identified as the major compound (40.78%, 26.24% and 27.04%) in PD medium and it was suggested as a chemical marker for this fungus. The use of multivariate data analysis (PCA) and (HCA) allowed the discrimination of the volatile chemical profiles according to the culture medium.
