Scientific name

Meliola bidentata Cooke [IndexFungorum. Sylloge Fungorum 2 (Addenda to volume 1); 9: 417; 12: 424; 19: 417; 20: 59; 26: 105]

Synonyms

None noted.

Vernacular names

None known.

Taxonomic position

Meliolaceae, Meliolales, Sordariomycetes, Ascomycota, Fungi.

Red List assessment

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

Rationale

This evaluation is based on 411 records [breakdown: Cybernome (1 record); IndexFungorum (1 record); other catalogues (6 records)]. There are 248 records with dates, the earliest 1880 (the species was first described in 1882), the most recent 2015. Of dated records, 6% are post 1960. This species is recorded from 14 countries distributed through 4 continents and regions. This fungus is known to occur in association with 29 other species belonging in 20 genera. Although this species is widely distributed and associated with more than one other genus, only a small proportion of dated records were made after 1960.

Reasons for change from previous assessment

None: not previously assessed.

Date of 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 1882. There are 248 datable records of this species. The earliest is 1880 and the most recent is 2015. The profile of dated records is: pre-1961 (234); 1961-2000 (13); post-2000 (1); 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): Cuba (10%); Puerto Rico (15%); Virgin Islands (unspecified) (no information) [figures from 'Forest change' tab of Global Forest Watch].
