None noted.

Vernacular names

None known.

Taxonomic position

Meliolaceae, Meliolales, Sordariomycetes, Ascomycota, Fungi.

Red List assessment

Data Deficient [possibly Least Concern] [IUCN Red List Categories and Criteria: version 3.1. Level: global].

Rationale

This evaluation is based on 45 records [breakdown: Cybernome (1 record); IndexFungorum (1 record); other catalogues (1 record)]. There are 19 records with dates, the earliest 1895 (the species was first described in 1953), the most recent 1986. Of dated records, 21% are post 1960. This species is recorded from 3 countries distributed through 3 continents and regions. The fungus is known only in association with Acacia. This species is widely distributed and associated with more than one other species (but only in one genus). An appreciable proportion of the dated records were made after 1960, suggesting that this species may eventually be evaluated as 'Least Concern'.

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 1953. There are 19 datable records of this species. The earliest is 1895 and the most recent is 1986. The profile of dated records is: pre-1961 (15); 1961-2000 (4); post-2000 (0). 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): Australia (22%); Malaysia (32%); New Caledonia (2.1%) [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).
