Assessment Notes


This species is thought to have occurred throughout French Guiana and Guyana, within forest dominated by Dicymbe corymbosa, however all known collections of this species are now thought to be preserved by the Fungi of French Guiana Collection, NMNH Extant Specimen Records, or the New York Botanical Garden Herbarium, or exist as sample material as part of the International Barcode of Life Project. In this species’ known past localities, there don’t appear to be any significant threats to this species, and information regarding the conservation status of Dicymbe corybosa, with which this species occurs, appears to be lacking. Until further research yields new information regarding this species’ current distribution, habitat preferences, and potential threats, it is listed as DD.

Taxonomic notes

Why suggested for a Global Red List Assessment?

Chanterelle species

Geographic range

This species is known to occur within Guyana, in its Pakaraima Mountains. Henkel et al 2009 describe their collections of this species as follows, ‘Collections were made during the May–July rainy seasons of 2000–2004 from the Upper Potaro River Basin, within a 5 km radius of a permanent base camp at 5° 18’ 04.8” N; 59° 54’ 40.4” W; elevation 710 m. This collecting site is located in an undulating valley approximately 20 km east of Mt. Ayanganna (2200 m), and is densely forested with a mosaic of primary Dicymbe-dominated and mixed forests of the Eschweilera-Licania association (Henkel 2003). An additional collection was made from the Upper Ireng River Basin, ~30 km south of the Potaro site, in May 1998. All collections were made in forests dominated by Dicymbe corymbosa’. Several preserved specimens from French Guiana as well as Guyana are known to have been collected between June 2008 and July 2013. All records of specimens of this species are either preserved by the Fungi of French Guiana Collection, NMNH Extant Specimen Records, or the New York Botanical Garden Herbarium, or exist as sample material as part of the International Barcode of Life Project (information provided by gbif, citation needed).

Population and Trends

This species does not appear to be threatened in its native range, and exists under preservation otherwise. Therefore, it is reasonable to assume that this species’ population is stable. Further research into the trends of its associated species may be useful in predicting this species’ future trends.

Population Trend: Stable

Habitat and Ecology

Collections of this species have been made in rainforests dominated by Dicymbe corymbosa, growing on the soil and humus underneath (Henkel et al 2009). Information regarding other collections of this species is fairly lacking, although this species is known to grow on sloped terrain (geographic points provided by gbif).

Subtropical/Tropical Moist Montane Forest


Information regarding the conservation status of Dicymbe corymbosa, with which this species appears to associate, does not appear to be available. This species does not appear to exist within threatened habitat.

Conservation Actions

No conservation action can be recommended at this time without further research, due to a lack of apparent threats to this species’ habitat, as well as an uncertainty as to its locality in some cases.

Research needed

Further research into this species’ specific locality and any threats which may be affecting it is needed in order to accurately classify this species. Furthermore, research into Dicymbe corymbosa may be useful in assessing whether Craterellus excelsus is likely to be impacted by the former’s population changes.
