Assessment Notes

Justification

Cantharellus iuventateviridis is a recently described species from the Gulf Coast (Buyck et al. 2016). Data to assess population size, trends and preferred habitat are lacking at this time, and it could theoretically qualify for any category. Therefore it is assessed as Data Deficient (DD).

Taxonomic notes

Cantharellus iuventateviridis was described from Mississippi, USA (Buyck et al. 2016). Cantharellus iuventateviridis is the southern 'sister taxon' to the very similar looking Cantharellus chicagoensis (Leacock et al. 2016). It is not known at this time if these two species overlap in range.

Geographic range

This species is currently known from southern Louisiana, USA east into Florida. Being a newly-described species (Buyck et al. 2016), the distribution is poorly known at this time.

---

Population and Trends

Being a newly-described species (Buyck et al. 2016), the population size remains poorly known. It is currently known from seven locations (MyCoPortal 2021). Reports on community science sites (e.g. Mushroom Observer, iNaturalist) of fungi from much of the range remains low in comparison to other areas of USA, so data to make an informed assessment is lacking.

Population Trend: unknown

Habitat and Ecology

Cantharellus iuventateviridis is ectomycorrhizal, likely associated with Water Oak (Quercus nigra), but pine (Pinus spp.) and American Hornbeam (Carpinus caroliniana) were noted in the area (Buyck et al. 2016). It typically fruits from bare soil in wet or muddy places (Buyck et al. 2016). However these observations are based on a very small sample size, and more ecological data is needed to clarify the habitat requirements and ecological constraints of this species.

Threats

No specific threats have been identified at this time with regards to this species. However, more information is needed to make an robust assessment on potential threats.

---

Conservation Actions

No specific conservation actions have been identified with regards to this species at this time. A better understanding of population numbers, distribution, and trends of Cantharellus iuventateviridis is required. Well-documented collections are needed with detailed habitat notes, and targeted surveys in the Gulf States for this species are recommended.

Use and Trade

All North American Cantharellus species are edible, but details are lacking about specific collection of Cantharellus iuventateviridis.
