The type specimen of this species was located within the Upper Potaro River Basin, Guyana. Further specimens have been located in the vicinity of the Potaro base camp, and always within forest dominated by Dicymbe corymbosa. No geographic coordinates appear to be available regarding this species’ distribution, making it difficult to assess whether any wild populations remain at these localities. This species is known to occur within Dicymbe corymbosa forest, but has also been noted to occur on sticks, mosses, living roots, and decaying wood. This species could be threatened by logging at its known localities, however further information is required in order to confirm this claim. Until further research yields new relevant information to this assessment, this species is listed as DD due to a lack of recent geographic records and confirmation of threats.
This species is now in the genus Craterellus.
Why suggested for a Global Red List Assessment?
The type specimen of this species was located within the Upper Potaro River Basin, approximately 20km East of Mt Ayanganna, 1km North of its base camp along the eastern river bank, at an altitude of 710m in June 2003 (Henkel et al 2006). Further specimens have been located in the vicinity of the Potaro base camp at similar elevations, always within Dicymbe corymbosa forest.
Population and Trends
This species is currently thought to be restricted to Guyana, within a relatively small area of moist tropical forest dominated by Dicymbe corymbosa. Given the potential threat of logging in this area, it is likely that this species’ habitat is under threat. This species does not appear to exist under protection or preservation, and so its current population is thought to be decreasing.
Population Trend: Decreasing
Habitat and Ecology
This species is known to occur within forests dominated by Dicymbe corymbosa. It has been noted to occur on sticks, mosses, living roots, and decaying wood. The following passage describes this species’ known habitat preferences, ’ Gregarious to imbricate in small troops at positions elevated from the forest floor, on decayed woody substrata and humic deposits on the trunks of living trees. Infrequently encountered during the May–July rainy season in forests dominated by the ectomycorrhizal canopy tree Dicymbe corymbosa’ (Henkel et al 2006).
Subtropical/Tropical Moist Lowland Forest
This species’ habitat could be threatened by logging, however further research is needed to confirm this as certainty.
This species likely exists within threatened habitat, and so protection of this habitat is required for the effective conservation of this species.
Resource & habitat protection
Further research into this species’ specific distribution and potential threats is required in order to accurately classify this species.
