Assessment Notes

Justification

Cantharellus pseudoformosus is only known from Himachal Pradesh in northwestern India. It occurs in forests, associating with Cedrus deodara. Within the known range the population size could be fairly small, estimated to fall in the range 300-3,000 mature individuals. Thus, under criterion D the species could fall anywhere between Vulnerable and Least Concern. There is little evidence of any rapid forest cover loss within this range, though, and so the species is suspected to be stable and would not approach the conditions for listing as threatened under any other criteria. A precautionary outlook is taken here, with a listing as Vulnerable under criterion D1. However, further research into the full range of the species, and to ascertain a clearer population size, as this value could be an underestimate, and with further information a re-evaluation of its status may be warranted.


Taxonomic notes

The paratype potentially could represent a different species (I. Olariaga Ibarguren in litt. 2022).


Why suggested for a Global Red List Assessment?

Chanterelle species


Geographic range

This species is only known from Himachal Pradesh, India in the west of the Himalayas (Kumari et al. 2011). Collections have been made at Khajjiyar, Suala and Bharmour (Kumari et al. 2011). The paratype as noted in Kumari et al. (2011) (the Bharmour collection) could potentially represent a different species (I. Olariaga Ibarguren in litt. 2022). However, Deepika et al. (2013) give a different collection date for a collection at the paratype locality, which suggests this site is valid for the species, and potentially the incorrect specimen number was noted in the type paper.


Population and Trends

Currently known from three sites (if the paratype locality is accepted and retained), the amount of suitable habitat within its known range could increase the potential number of sites there by 10 to 20 times. It is a gregarious/caespitose growing species, and so using Dahlberg and Mueller (2011) the number of mature individuals per functional individual would be at the upper end of the scale, i.e. 10 mature individuals per functional individual. With so limited collections of the species, the number of functional individuals per site is likely to be small, and taking a precautionarily broad estimate of one to five functional individuals per site, would then give a range of 300-3,000 mature individuals. If the species were to occur throughout the range of its potential host, Cedrus deodara, though, this would represent an underestimate.

At the moment there is little evidence to suggest that the forest where the species occurs is in decline (see World Resources Institute 2023), and so tentatively the population is suspected to be stable.

Population Trend: Stable


Habitat and Ecology

This species has been reported growing within mixed evergreen forests of the western Himalayas, India, on the soil under Cedrus deodara, a species which can support a great number of ectomycorrhizal fungal species (Kumari et al. 2011).

Temperate Forest

Threats

Very little forest cover loss has been recorded within the potential range of this species (see World Resources Institute 2023), and it is not suspected to face any substantial threats.


Conservation Actions


Research needed

Further research is required to ascertain how widespread it may be; both within its known range, and also potentially within the range of its possible host species. Such research could also help to get a clearer estimate of the population size.
