The textual criticism of original species of Hongxuecha has been made combining species identification and field surveys. The results showed that Hongxuecha had two original species, Lethariella cladonioides and L.zahlbruckneri. There were chemical variability within the two populations. Hongxuecha in the market sales included four chemical races of the two species. The distribution center of Hongxuecha was mainly in the southeastern Tibet, western Sichuan and northwestern Yunnan. Currently, Hongxuecha resources have been greatly damaged and species are facing extinction. To enhance effective protection for wild hongxuecha resources, some proposals were presented.
