Assessment Notes

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

Taxonomic notes

Only species in the Scotomyces genus. It was included in a phylogenetic study of corticioid fungi (Larsson 2007), but its phylogenetic placement remains unclear. Synonyms: Hypochnus subviolaceus, Ceratobasidium atratum, Ceratobasidium plumbeum, Ceratobasidium subatratum, Corticium atratum, Corticium fallax, Hydrabasidium subviolaceum, Hypochnus subviolaceus, Oliveonia atrata, Oliveonia subviolacea, Scotomyces fallax, Tulasnella metallica (Species Fungorum, 2023).


Why suggested for a Global Red List Assessment?


Geographic range

S. 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 (South-eastern Australia and New Zealand). (GBIF.org, 2023; MyCoPortal, 2023; Contreras-Pacheco et al., 2018; Ambrosio, 2014; Prasher and Ashok, 2013)


Population and Trends

S. 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 projected to be above 342000 individuals.

Population Trend: Uncertain


Habitat and Ecology

S. 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).
