    Notes:
    • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details.

• Notes:
  • 🧬 The phylogenomic assignment score of this taxon is 0.08845 (N = 7).
  • 😷 The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 2, note = "t". — 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.
