Red List assessment

Data Deficient [probably Vulnerable] [IUCN Red List Categories and Criteria: version 3.1. Level: global].

Rationale

This evaluation is based on 46 records [breakdown: Cybernome (1 record); IndexFungorum (1 record); other catalogues (2 records)]. There are 24 records with dates, the earliest 1909 (the species was first described in 1928), the most recent 2012. Of dated records, 8% are post 1960. This species is recorded from 8 countries distributed through 4 continents and regions. This fungus is known to occur in association with 14 other species belonging in 6 genera. This species is widely distributed and associated with more than one other genus. Only a small proportion of dated collections were made after 1960, suggesting that this species will probably eventually be evaluated as 'Vulnerable'.

Reasons for change from previous assessment

With no direct information, observation frequency over time, if available, can be considered as a proxy to infer current population trend; for species associated with trees, loss of woodland cover over time is another possible proxy. Observation frequency over time. The species was first described in 1928. There are 24 datable records of this species. The earliest is 1909 and the most recent is 2012. The profile of dated records is: pre-1961 (22); 1961-2000 (1); post-2000 (1); Observations have declined sharply. Loss of tree cover over time. This species occurs associated with trees in the following countries (percentage loss of tree cover between 2001 and 2024 in brackets): Brazil (14%); Sierra Leone (39%) [figures from 'Forest change' tab of Global Forest Watch]. Current trend (inferred). Long-term steep decline possibly driven by habitat destruction. The small number of datable records makes this inference very uncertain. Conservation actions (in situ).
