Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/266016423/266019042

Justification

Scotomyces subviolaceus is a resupinate species with a very wide distribution, large population size, and there is no evidence of a population decline. Therefore, it is assessed as Least Concern (LC).

Taxonomic notes

This is the only species in the Scotomyces genus. It was included in a phylogenetic study of corticioid fungi (Larsson 2007), but its phylogenetic placement remains unclear.

Geographic range

Scotomyces subviolaceus has a very wide distribution, though its limits are not well defined. It has been recorded in North and South America, Europe (including the Azores and Faroe Islands), Asia (Turkey, north of India and in Far East Russia), Africa (Uganda, Kenya and the island of Réunion) and Oceania (southeastern Australia and New Zealand) (Prasher and Ashok 2013, Ambrosio 2014, Contreras-Pacheco et al. 2018, GBIF.org 2023, MyCoPortal 2023).

Population and Trends

Scotomyces subviolaceus is known from approximately 114 sites in total. It may be locally uncommon but given its wide distribution and large area of appropriate habitat the total number sites, including those not yet known, is expected to be much larger. Following guidelines by Dahlberg and Mueller (2011), population size is estimated to be in the hundreds of thousands.

Population Trend: Unknown

Habitat and Ecology

Scotomyces subviolaceus is a saprotrophic, annual resupinate species. It grows on dead wood in both deciduous and coniferous forests and in cultivated land (SLU Artdatabanken 2020).

Threats

No significant threats have been identified for this species.

Conservation Actions

No specific conservation actions are needed.
