Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/269705139/269705141

Justification

Even when first described there were some taxonomic doubts about the generic placement of this species, and it appears as if it remains to be known solely from a solitary collection made in 1905. Without any more recent information it is not possible to accurately assess the extinction risk of this species and so it is assessed as Data Deficient.

Taxonomic notes

Given how this species has been found growing on rotten branches, it is suspected not to be cantharelloid (I. Olariaga Ibarguren in litt. 2022); and even in the description of the species it was described as "Cantharellus ? niveus", with the note that it may be better placed in Marasmius (Spegazzini 1909).

Geographic range

This species appears to be known solely from a collection made in 1905 in woodlands of the Rio Seco in northwestern Argentina, near Orán (Spegazzini 1909). Note that while the type description places this as within Jujuy province (see Spegazzini 1909), this is actually within Salta province.

Population and Trends

The population size and trend are unknown.

Population Trend: Unknown

Habitat and Ecology

It has been recorded fruiting solitarily in April (Spegazzini 1909), and was collected from fallen rotten branches in woodland (Spegazzini 1909).

Threats

Without further information regarding the full distribution of the species an accurate assessment of the threats it faces cannot be made.

Conservation Actions

Further research is required on Cantharellus niveus. This should focus on trying to ascertain the full distribution of the species, which can then give an indication towards the threats it faces, and provide more ecological information. It would then also aid towards an estimation of the population size and trend. The taxonomy of this species also needs to be resolved, particularly regarding its generic placement.

Use and Trade

There is no use/trade information.
