Cordyceps militaris Raw Material & Plant Part
The scientific name is Cordyceps militaris (L.) Fr., family Cordycipitaceae, the type species of the genus. In nature the fungus grows from buried insect pupae or larvae. In commerce it is cultivated on grain-based media, and some recipes add silkworm pupa powder. The part used here is the fruiting body, the orange club that emerges from the substrate.
Three raw materials carry similar names and are not interchangeable: the fruiting body of C. militaris, mycelium biomass grown in liquid or on grain, and wild caterpillar fungus. The wild caterpillar fungus is a different species, Ophiocordyceps sinensis, which was moved to the family Ophiocordycipitaceae after DNA studies in 2007. It is the one usually meant by the traditional name cordyceps.
The dried fruiting body is light, fibrous and orange to brown, and the milled powder is light brown. Substrate residue, spent grain and the insect host are not part of this raw material, which is a point worth stating in any specification.
In a specification, cordyceps mushroom powder should state the part and the species in words. A listing that says cordyceps powder without the part may refer to mycelium on grain, which is a different material, or to the wild caterpillar fungus, which is a different species. The words dried fruiting body and Cordyceps militaris make the raw material unambiguous.
