Abstract: © 2019 The Mycological Society of Japan A stinkhorn fungus was collected from the mountainous area of Yoshida campus, Yamaguchi University, Japan. Morphological characterization and similarity of large subunit ribosomal DNA sequences identified the fungus as Pseudocolus fusiformis. MonoTrap™ was combined with gas chromatography-mass spectrometry (GC-MS) to identify volatile organic compounds (VOCs) emitted from the fungus harvested at different stages of maturity. The main VOCs emitted from the mature fruiting body were 3-methyl-butanol, 4-methyl-phenol, and dimethyl tetrasulfide, while none of these compounds were detected in the egg-shaped state. Volatile sulfur-containing compounds, including dimethyl disulfide, trisulfide and tetrasulfide, which are commonly detected in stinkhorn fungi and truffles, were also emitted from this fungus. Furthermore, results elucidated that most VOCs occurred in the mature stage of Ps. fusiformis (fruiting body with arms fuse). This is the first study reporting VOC production of Ps. fusiformis.
