title: Failed PCR of Ganoderma type specimens affects nomenclature.
abstract: The nomenclature of Ganoderma used as a Chinese medicine is debated. A group of researchers could not amplify the DNA of type specimens and concluded the DNA was degraded irreparably. New topotypes were used as the type specimens which was premature. The use of internal amplification controls is recommended to determine if other factors were involved as alternative explanations.
