In other words, the name "Tricholoma magnivelare" probably applies to northeastern matsutakes--but should be changed to one of the older names (Tricholoma matsutake or Tricholoma nauseosum; see comments below) . . . while western and Mexican matsutakes currently lack scientific names. Even more disturbing is the fact that differences in physical features (for example, brown caps versus white caps) appear not to correlate with significant genetic differences.
