In the course of a study of fungal biodiversity of opium poppy (Papaver somniferum) plants collected in production area of Slovakia, an ascomycete belonging to the genus Subramaniula was isolated. The fungus identified as Subramaniula thielavioides has been reported for the first time from Slovakia. This record also represents the first European locality. Brief morphological description of the fungus based on an isolate from flower petals of opium poppy is provided.
Ash dieback, caused by Hymenoscyphus fraxineus, is a serious disease of common and narrow-leaved ash in Europe. The resistance of individual trees seems to be important for the maintenance of ash in European forests. In this in situ wound inoculation study, the susceptibility and differences in resistance to H. fraxineus between Fraxinus excelsior and F. angustifolia clones were assessed. Neither of the tested clones revealed total resistance to ash dieback; variety between the tested clones was observed. Differences in necroses lengths were significant between clones and between two ash species. Longer necroses were formed in F. angustifolia than in F. excelsior. Some clones exhibiting some resistance to the pathogen were identified.
