The lipid, fatty acids, and sterol content of a pure preparation of the intramatrical vesicles of a Glomus sp. were determined. Lipid content of vesicles was 58.2% of the dry mass. The predominant lipid fraction was glycolipid and sphingolipid (44.5% of total lipid) followed by neutral lipid (25.5%) and phospholipid (24.2%). The fatty acids were examined by gas liquid chromatography. While 16:1 fatty acid was exceptionally high in the neutral and glycolipid fraction (60% and 51.2% of the total fatty acids), 18:2 was the predominant fatty acid in the phospholipid fraction (70.9%). The sterol content of the intramatrical vesicles was 5.8% of the spore dry mass (11.3% of total lipid). These results are compared to other lipid information available on the VAM and other fungi.
