Scientific name

Meliola begoniae Hansf. [IndexFungorum. Index of Fungi 1: 188]

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 21 records [breakdown: Cybernome (1 record); IndexFungorum (1 record); other catalogues (1 record)]. There are 7 records with dates, the earliest 1944 (the species was first described in 1947), the most recent 1972. Of dated records, 29% are post 1960. This species is recorded from 3 countries in a single continent or region. The fungus is known only in association with Begonia. Although this species is known from more than one country, associated with more than one other species (but only in one genus), and an appreciable proportion of dated records were made after 1960, there are too few records to make any other evaluation.

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 1947. There are 7 datable records of this species. The earliest is 1944 and the most recent is 1972. The profile of dated records is: pre-1961 (5); 1961-2000 (2); 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.
