Five new acetylenic acid analogues, craterellynes A-E (1-5), together with three known compounds (6-8), were isolated from the fruiting bodies of Craterellus lutescens. Their structures were elucidated on the basis of spectroscopic and chemical means. The absolute configurations of 1-6 were determined by the modified Mosher method.
