Cantharellus fibrillosus is only known from specimens collected in temperate forest in the region of Simla, Himachal Pradesh, India. If the species were to be restricted to this area its population size would be very small, and it could even warrant a listing as Critically Endangered. However, the tree species that it was found under have very wide ranges throughout the Himalayas, and so if it were to occur throughout this range then the species could warrant listing as Least Concern. Given the high levels of uncertainty, C. fibrillosus is assessed as Data Deficient.
Why suggested for a Global Red List Assessment?
Cantharellus fibrillosus is known from Dhalli forest and Khada Pathar forest in Himachal Pradesh, India, not far from Simla (Deepika et al. 2013). Specimens were found on soil under Cedrus deodara and Pinus wallichiana (Deepika et al. 2013), and these species have very wide ranges in the Himalayas (Farjon 2013a,b), so its full distribution could be a lot larger than currently known.
Population and Trends
This species is considered to be gregarious or growing in clumps, where it has been found (Deepika et al. 2013). Despite this, given that its known range is very restricted the total known population size could be very small. On the other hand, species is has been found growing under are very widespread in the Himalayas (Farjon et al. 2013a,b), and so the population size could be very large. In essence, therefore, the population size is unknown. There are some ongoing threats to the trees it has been found growing under, but it is currently not possible to accurately translate these into an idea of the overall population trend of Cantharellus fibrillosus.
Population Trend: Uncertain
Habitat and Ecology
This species has been collected from temperate forests in north-west India (Deepika et al. 2013). Specimens were found on soil under Cedrus deodara and Pinus wallichiana (Deepika et al. 2013).
Anthropogenic practices such as agriculture and logging could be having an impact on potential host species (Farjon et al. 2013a,b), and given its high altitude habitat, it is possible that climate change could pose a future threat.

Further research is required in order to ascertain the full distribution of the species, and its potential host specificity.
