Craterellus subperforatus has been collected from coniferous bog forests from three different states in north-eastern USA. Given how widespread this habitat is, then the overall distribution of the species is suspected to be very large. The species has also been described as gregarious, and so the global population size is unlikely to be particularly small. The population trend in uncertain, but it is not suspected to approach the thresholds for listing under criterion A. Therefore, C. subperforatus is assessed as Least Concern.
Why suggested for a Global Red List Assessment?
This species has been recorded from Michigan, Maine and Massachusetts in north-eastern USA. It is presumably more widespread in this part of the country, and it probably occurs in southern Canada as well given its known distribution.
Population and Trends
There is no quantitative information on population size and distribution, but it is described as ‘gregarious’ (Smith 1968, Bigelow 1978).
Population Trend: Uncertain
Habitat and Ecology
The genera Craterellus consists of species forming ectomycorrhizal associations with trees. Craterellus subperforatus is reported as a gregarious species, which appears to be mostly associated with damp areas (Smith 1968, Bigelow 1978). Collections of this species have been made on moss in coniferous bogs containing trees of the genera Abies, Tsuga and Thuja (Smith 1968, Bigelow 1978). Collections were made between August and October (Smith 1968, Bigelow 1978).
Bogs, Marshes, Swamps, Fens, Peatlands [generally over 8 ha]
It is not thought that the species faces any significant threats at the moment.
Further research to get an idea of the full range (e.g. confirming how many more states in New England it may occur in, or if it may occur in southern Canada), and to estimate the overall abundance of the species could be beneficial.
