Domain: Eukaryota
Kingdom: Fungi
Subkingdom: Dikarya
Phylum: Ascomycota
Subphylum: Pezizomycotina
Class: Pezizomycetes
Order: Pezizales
Family: Pyronemataceae
Genus: Ramsbottomia
Species: Crechqueraultii

Ramsbottomia crechqueraultii published by Benkert, D.; Schumacher, T. in 1985: Emendierung der Gattung Ramsbottomia (Pezizales). Agarica. 6(12):28-46. While this fungus is a member of the Ramsbottomia genus, it is also frequently identified as Lamprospora crechqueraultii,  (P. Crouan & H. Crouan) Boud., Histoire et Classification des Discomycètes d’Europe: 69 (1907) . Lamprospora is another genus in the Pyronematacaea family. The species name of this fungus is also alternatively spelled crec’hqueraultii.

Why suggested for a Global Red List Assessment?

Ramsbottomia crechqueraultii is a fungus with a wide global distribution, thus making it less susceptible to extinction due to local threats. Population data, while limited, does not signal a general decline. Therefore, we suggest that this fungus be listed as Least Concern (LC) pending other research into population data.

Geographic range

This species has a wide geographic range, having been observed in North America, Europe, Asia, South America, and southern Australia. In all of these regions, it is confined to temperate or boreal climates, and does not occur in places with extreme temperatures. Nevertheless, it has a wide distribution globally.

Population and Trends

The data available about the population size of this species is limited. While seen widely around the world, it is still infrequently documented, both in the past and in recent years. This could indicate a small population in each location or a lack of data generally, but it gives little indication of the total global population or if how it is changing over time. Due to its wide distribution, however, we are still proposing that this species be labeled as Least Concern, despite this gap in population data.

Population Trend: Uncertain

Habitat and Ecology

Ramsbottomia crechqueraultii is a ground-dwelling fungus, and grows in moist soil in temperate or boreal regions, often near water sources. It is frequently seen growing in areas where various species of moss and carex also grow, although it lives independently of these species.

As this fungus is reliant on moist soil and the availability of water sources, global warming poses a threat to this species. Increases in local and global temperatures can change the qualities of the soil on which it depends, and lead to higher average annual temperatures, which would be deleterious to a fungus that exists in temperate and boreal biomes. Additionally, habitat loss due to human development can be detrimental to this fungus, as its soil environment is disrupted or the water sources it depends on are destroyed or siphoned off for human use. However, due to its wide distribution globally, local effects are not as threatening to this fungus as global effects, like climate change.

Conservation Actions

Until more information is known about the population numbers and trends for this species, no conservation efforts are warranted, on account of its wide distribution. We are suggesting that this species be listed as Least Concern for the time being.

Research needed

While this fungus has a wide distribution, and thus is less susceptible to extinction threats on account of habitat loss at local levels, there is still research needed to properly gauge population numbers and trends globally. The data of sightings for this fungus that is available is limited; even then, this data is primarily documentation of sighting times and locations, and lacks information about the number of mature individuals found at each location and the broader population size found in those areas. In order to better understand the population trends over time for Ramsbottomia crechqueraultii, more research is needed to accurately determine this data.
