Ergoline (i.e., ergot) alkaloids are a group of physiologically active natural products occurring in the taxonomically unrelated fungal and plant taxa, Clavicipitaceae and Convolvulaceae, respectively. The disjointed occurrence of ergoline alkaloids seems to contradict the frequent observation that identical or at least structurally related natural products occur in organisms with a common evolutionary history. This problem has now been solved by the finding that not only graminaceous but also some dicotyledonous plants belonging to the family Convolvulaceae, such as Ipomoea asarifolia and Turbina corymbosa, form close associations with ergoline alkaloid producing fungi, Periglandula ipomoeae and Periglandula turbinae. These species belong to the newly established genus Periglandula within the Clavicipitaceae. The fungus-plant associations are likely to be mutualistic symbioses.
