Table 3 in Discovery of a new species of the Hypoxylon rubiginosum complex from Iran and antagonistic activities of Hypoxylon spp. against the Ash Dieback pathogen, Hymenoscyphus fraxineus, in dual culture

Table 3. Identified secondary metabolites in axenic cultures on barley-malt medium of the surveyed strains. Strains in bold have been used concurrently against STMA 18166 (Hymenoscyphus fraxineus) in an antagonism assay. Identified compounds: 5: phomopsidin; 6: 10-hydroxyphomopsidin; 8: rickiol A; 9: orthosporin 10: daldinone B; 11: 1,8-dimethoxynaphtahlene; 13: 5-methyl-mellein. Identified stromal azaphilone groups detected in culture: MI = Mitorubrin type; NA = Naphthalene type; DA =Daldinin type. For chemical structures, see Fig. 8.
