Scientific name

Meliola batangasensis Hansf. [IndexFungorum. Index of Fungi 2: 388]

Synonyms

None noted.

Vernacular names

None known.

Taxonomic position

Meliolaceae, Meliolales, Sordariomycetes, Ascomycota, Fungi.

Red List assessment

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

Rationale

This evaluation is based on 18 records [breakdown: Cybernome (1 record); IndexFungorum (1 record); other catalogues (1 record)]. There are 8 records with dates, the earliest 1915 (the species was first described in 1957), the most recent 1923. This species is recorded only from Philippines. The fungus is known only in association with Homalium. This species appears to be an endemic of Philippines, suggesting a limited distribution. It is associated with more than one species (but only in one genus), but all records are very old and there are too few records to make any other evaluation. Possibly a name needing further taxonomic investigation.

Reasons for change from previous assessment

None: not previously assessed.

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 1957. There are 8 datable records of this species. The earliest is 1915 and the most recent is 1923. 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): Philippines (8.2%) [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).
