Documentation forms for state and global ranks for fungi are provided in the table below. Where taxa have recently changed scientific names, the previously used name is noted in the Previous Name column. For detailed information on the ranking process, see Ranking Documentation. For a brief description of the meaning of the rank codes, see Rare Species Ranking Definitions. Fields with an en dash ( – ) denotes that the species has not been documented in that state, at least at the time of the assessment. Results from the 2016-2018 fungi ranking effort can be downloaded in an Excel spreadsheet.
