In The Red List Assessment of Macrofungi in China project, the IUCN Red List Categories and Criteria were adjusted according to differences in biological characteristics among plants, animals, and macrofungi. The adjustments are as follows: (1) population fluctuation and mature population members were estimated according to visible distribution and fruiting bodies, (2) a certain time period (rather than generation time) was used to calculate population change, (3) Possibly Extinct was added as an additional threatened category. The assessed data was based on the Checklist of Fungi in China database, fungal taxonomy literature, and expert consultation. Lastly, the Red List of China’s Biodiversity—Macrofungi was compiled via task assignment, data collection, assessed species verification, initial assessment, expert assessment, and red list compilation.

Key words: IUCN, red list categories and criteria, Possibly Extinct, macrofungi, assessment procedure
