Scientific name

Meliola balansae Gaillard [IndexFungorum. Sylloge Fungorum 11: 266; 12: 424; 20: 59]

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 12 records [breakdown: Cybernome (1 record); IndexFungorum (1 record); other catalogues (3 records)]. There are 2 records with dates, the earliest 1873 (the species was first described in 1892), the most recent 1907. This species is recorded from 3 countries in a single continent or region. The very few records, from more than one country but associated with only one other species, are all very old: possibly a name needing further taxonomic investigation.

Reasons for change from previous assessment

None: not previously assessed.

Date of assessment

29 November 2025.

Name/s of the assessor/s

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 1892. There are 2 datable records of this species. The earliest is 1873 and the most recent is 1907. 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%) [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).
