Synonyms

None noted.

Vernacular names

None known.

Taxonomic position

Meliolaceae, Meliolales, Sordariomycetes, Ascomycota, Fungi.

Red List assessment

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

Rationale

This evaluation is based on 48 records [breakdown: Cybernome (1 record); IndexFungorum (1 record)]. There are 19 records with dates, the earliest 1924 (the species was first described in 1930), the most recent 1939. This species is recorded from 4 countries distributed through 3 continents and regions. This fungus is known to occur in association with 8 other species belonging in 2 genera.

Reasons for change from previous assessment

None: not previously assessed.

Date of assessment

Not known. 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 1930. There are 19 datable records of this species. The earliest is 1924 and the most recent is 1939. 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): Costa Rica (7.3%); Democratic Republic of the Congo (11%); 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).
