There is limited information available from the type description, and only two likely records of C. devexus. With a lack of occurrence data and information on the habitat and ecology of the species, it is not possible to assess the status of its population or distribution.
It is therefore now assessed as Data Deficient.
Described by E.M. Fries under the basionym Agaricus devexus in 1821 and subsequently as Cantharellus devexus by P.A. Saccardo in 1887.
Index Fungorum lists the following as additional synonyms of A. devexus; Cantharellus replexus * devexus (Fr.) P. Karst., Cantharellus replexus var. devexus (Fr.) Fr. and Merulius devexus (Fr.) Kuntze.
From the original description it does not appear to resemble a Cantharellus (I. Olariaga Ibarguren pers. comm. 2022).
Why suggested for a Global Red List Assessment?
Chanterelle species to be assessed as part of the chanterelle comprehensive project.
The range of this species is essentially unknown. It is unclear where the type material for came from beyond the broad region of Europe (see Fries 1821).
There are two recorded occurrences on GBIF (2023), one from the Stockholm area of Sweden (held in the Swedish Museum of Natural History as a preserved specimen), and one from the United Kingdom, to the east of Colchester in Essex. The latter is listed as a human observation, with identification unconfirmed (yet plausible), and is listed under the synonym Cantharellus replexus var. devexus.
Without any information about the habitat requirements of the species, it is not possible to infer the extent of the range.
Population and Trends
There are no quantitative data available to be able to assess the population size and trend.
Population Trend: Uncertain
Habitat and Ecology
The basionym was described from the ground in November (Fries 1821), but no other information is available.
No threats can be accurately identified due to the lack of clear information about the true distribution of the species.
Confirmation of its taxonomic status, population and distribution data as well as its ecology are required to better assess this species’ conservation status.
