The taxonomic status of Grosmannia wageneri against the new Leptographium species in Choi et al. (2023) needs to be clarified (2025-03).

Grosmannia wageneri was previously considered as the teleomorph of Leptographium wageneri in EPPO Global Database. This code includes information on Grosmannia (Ophiostoma, Ceratocystis) wageneri and Leptographium wageneri before Choi et al. 2023. Choi et al. (2023) maintained L. wageneri var. wageneri as L. wageneri and elevated L. pseudotsugae and L. ponderosum (previously L. wageneri var. pseudotsugae and L. wageneri var. ponderosum) to species. Information on the new species is provided under their respective codes.
