  • 😩 Deposit incorrectly indicated in some sources as representing the type strain of this taxon: CCM 7824.
  • ❗ Pseudoduganella violaceinigra is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Pseudoduganella.
  • 😷 The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
  • 🎓 Name mentioned 5 times in PubMed until 2024-03-28.
