Based on the evidence of positive and negative ion mode FAB MS, the structure of cerebroside (1) was determined to be (4E,8E)-N-2-hydroxyhexadecanoyl-l-0-P-gluco-pyranosyl-9-methyl-Ci8-sphinga-4,8-dienine (Fig. 1), which had been isolated from Schizophyllum commune by Kawai and Ikeda [8] as a fungal fruiting body inducer.
