Red List assessment

Critically Endangered [IUCN Red List Categories and Criteria: version 3.1. Level: global].

Rationale

This evaluation is based on 73 records [breakdown: Cybernome (2 records); IndexFungorum (3 records); other catalogues (3 records)]. There are 30 records with dates, the earliest 1930 (the species was first described in 1923), the most recent 1957. This species is recorded from 8 countries distributed through 3 continents and regions. This fungus is known to occur in association with 12 other species belonging in 11 genera.

Reasons for change from previous assessment

None: not previously assessed.
