RESUMEN
<p><b>OBJECTIVE</b>To provide a rapid, simple, accurate and reproducible identification method from which Cordyceps sinensis can be distinguished from other species.</p><p><b>METHOD</b>To observe the larva and stroma of Cordyceps family with macroscopic identification method, and with powder microscopic identification method.</p><p><b>RESULT AND CONCLUSION</b>For macroscopic, only stroma of C. sinensis is mostly non-inflated, and un-obtuse at the tip, the caterpillar annulations of C. sinensis and the C. gracilis is distinct, about 20-30, and feet of above two are 8 pairs, 4 of 8 pairs are relatively distinct. The above appearance shows its unique characteristic. For microscopic identification, only C. sinensis exists microtrichia, the tip is pointed. The arranging order of stubby setae is irregular, the tip is blunt while the basal is gradually broader; the top of some setae bends slightly like a hook.</p>
