Taxonomic position

Meliolaceae, Meliolales, Sordariomycetes, Ascomycota, Fungi.

Red List assessment

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

Rationale

This evaluation is based on 41 records [breakdown: Cybernome (1 record); IndexFungorum (1 record); other catalogues (1 record)]. There are 18 records with dates, the earliest 1913 (the species was first described in 1914), the most recent 1979. Of dated records, 6% are post 1960. This species is recorded from 4 countries distributed through 2 continents and regions. This fungus is known to occur in association with 8 other species belonging in 4 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 1914. There are 18 datable records of this species. The earliest is 1913 and the most recent is 1979. The profile of dated records is: pre-1961 (17); 1961-2000 (1); post-2000 (0). Observations have declined sharply. Current trend (inferred). Long-term steep decline. The small number of datable records makes this inference very uncertain. Conservation actions (in situ). None known. Conservation actions (ex situ). Culture collections.
