The collection season and identification of Cordyceps sinensis

The Cordyceps sinensis collection season typically runs from May to August each year. It's crucial to harvest the fungus during the early stage of the "Summer" season—specifically, when the plant is still in its immature phase, often referred to as the "inflorescence" stage. Once the plant begins to flower, the mycelium of both the worm and grass parts will divert their nutrients to produce ascospores (the reproductive spores), leading to decay. **Tip 1:** There are hundreds of Cordyceps species, but identifying genuine Cordyceps sinensis can be challenging. Here are a few key features to look for: - **Geographic Origin:** True Cordyceps sinensis is only found on the Qinghai-Tibet Plateau. - **Physical Characteristics:** The fungus has an insect-like head and a grass-like stem. Inside the body, you'll find white mycelium. The "worm" part is usually yellow or brown, while the "grass" is green or brown. - **Cross-Section Marking:** When cut open, there's a distinct black spot in the center, which is the digestive gland of the original insect host. - **Texture and Breakability:** The body is hollow and can easily break apart when handled. **Tip 2:** Be cautious of imitations. Some products may be mislabeled or made from other Cordyceps species. Always purchase from trusted sources and consider having the product tested if you're unsure. By understanding these characteristics, you can better identify authentic Cordyceps sinensis and ensure you're getting the highest quality product available.
