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.
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).
Why suggested for a Global Red List Assessment?
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: Uncertain
Habitat and Ecology
It has been recorded fruiting solitarily in April (Spegazzini 1909), and was collected from fallen rotten branches in woodland (Spegazzini 1909).
Subtropical/Tropical Dry Forest
Without further information regarding the full distribution of the species an accurate assessment of the threats it faces cannot be made.
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.
