Abstract Aggregation of ascospores has been discovered in the yeast Dipodascopsis uninucleata. When this yeast is cultivated to reach the sexual reproductive stage, small ascospores are individually released from the tip of a sac-like ascus which then aggregate in orderly clusters. Acetylsalicylic acid (ASA) inhibited ascospore release and subsequent ordered aggregation process. We suggest that novel ASA-sensitive oxidised fatty acids (3 R-hydroxy-oxylipins) and small hooks located on the surface of these ascospores, are involved.
