Commercial Sample Identification and Characterization Challenges in Medicinal Mushroom Research

Int J Med Mushrooms. 2016;18(3):203-4. doi: 10.1615/IntJMedMushrooms.v18.i3.20.


A recent study published in this journal demonstrates the pitfalls faced by researchers who utilize commercial products as their test samples without proper characterization. Labeling of commercial mushroom products is often incorrect, which can lead to erroneous interpretations and conclusions. Nine of the 10 samples of commercially branded products used in the study and identified as ground mushrooms were actually grain spawn: mycelium propagated on grain.
