Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/198623181/198624713

Justification

Cantharellus phasmatis is a species of golden chanterelle that was described from hardwood forests in Wisconsin, USA, and has also been recorded from DNA confirmed collections from Tennessee, and a number of photographic records from across the Midwest and Mid-Atlantic regions. Most historic records would have been recorded under the catchall name for golden chanterelles, Cantharellus cibarius. It also appears to be morphologically indistinct from Cantharellus deceptivus, and can only be reliably distinguished by TEF-1 sequence data. Thus data to assess population size and trends are lacking, but based on its apparent habitat and the area encompassed by sequenced-confirmed collections, it is likely this species is widespread, common, and occurs in a stable habitat. Therefore, a Least Concern (LC) ranking is warranted.

Taxonomic notes

Cantharellus phasmatis was described from Wisconsin, USA (Foltz et al. 2013). Currently, it is believed to be morphologically indistinct from Cantharellus deceptivus, and can only be distinguished by TEF-1 sequence data (Buyck et al. 2016). The evidence for this is based on a low number of sequenced-confirmed collections, and future research may reveal currently unknown morphological differences. Previous to work published on golden chanterelles in North America (Buyck and Hofstetter 2011, Foltz et al. 2013) records of this species would have been recorded under the catchall name Cantharellus cibarius.

Geographic range

Geographic range remains poorly known for this species, due to lack of sequence-confirmed specimens. Currently it is known from sequenced collections from Wisconsin and Tennessee, USA (MyCoPortal 2021), and photographed observations (Mushroom Observer 2021) from across the Midwest, into New England, south to Tennessee and North Carolina. Records from the south-east (growing with pine) appear to be a different species. There are no sequenced-confirmed collections from Canada, but there are lots of pictures which appear to be C. phasmatis (i.e. Mushroom Observer2021, Mycoquebec 2021). However, it is not possible to distinguish it from C. deceptivus based on morphology, and so these cannot be treated as confirmed records of its presence in Canada without further study.

Population and Trends

Too little is known about Cantharellus phasmatis to make a robust assessment of population size and trends. Based on localities for which there are sequenced-confirmed subpopulations (Wisconsin and Tennessee), and the large number of photographic records across the Midwest and Mid-Atlantic which likely pertain to this species (although the lookalike Cantharellus deceptivus can only be distinguished by TEF-1 sequence data) suggest that population is widespread and stable.

Population Trend: stable


Habitat and Ecology

Cantharellus phasmatis is an ectomycorrhizal species associated with hardwoods. Foltz et al. (2013) report that it is "gregarious to scattered; associated with Quercus (Fagaceae) and Carya (Juglandaceae)". Other collections appear to have been made in oak (Quercus spp.) forests. More sequenced-confirmed collections with detailed habitat notes are needed to fully understand habitat requirements and ecological constraints of this species.

Threats

No specific threats have been identified with regards to this species.

Conservation Actions

No specific conservation actions have been identified with regards to this species at this time. More documented collections of Cantharellus phasmatis, detailing habitat and tree associations, are needed to better-understand the distributional extent and population status of this species.

Use and Trade

Cantharellus phasmatis (and all other golden chanterelles in North America) are edible, and are indiscriminately collected by foragers and small-scale commercial pickers.
