Mushrooms have long been appreciated as a delicacy as well as used as vital dietary supplements and food. However, poisoning from mushroom consumption remains a worldwide health problem, resulting in morbidity and mortality. In this paper, for the first time an untargeted lipidomics analysis on Omphalotus olearius (O. olearius) and Cantharellus albovenosus (C. albovenosus) was performed by ultra-high-performance liquid chromatography high-resolution accurate mass-mass spectrometry (UHPLC-HR-AM/MS/MS). A total of 350 lipid molecular species from 21 classes were detected in the two mushrooms. Based on multivariate and univariate analyses, 37 differential lipids were selected as metabolic markers for distinguishing the two mushrooms. And only 5 % (w/w) adulteration level was sufficient to identify C. albovenosus mixed with O. olearius. This study indicated that lipidomics approaches can provide high-resolution markers for food safety evaluation, which can be used as an accurate evaluation for distinguishing poisonous mushrooms from edible ones.
