There is limited information available from the type description, and only two uncertain specimens recorded of C. cuculatus. 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.  In addition, a synonymy issue should be examined to ensure that occurrence data is correctly ascribed to C. cuculatus in future.
It is therefore now assessed as Data Deficient.

Cantharellus cuculatus was described in 1830 by J.E. Duby as ‘Cantharellus cucullatus’ and it is named under the latter on Index Fungorum. The species was listed by E.M. Fries in 1832.

Merulius cucullatus (described by Louis de Brondeau in 1828) is listed as the basionym on Index Fungorum, but is not a named synonym on GBIF. Merulius cucullatus de Brond is named as a synonym of Plicaturopsis crispa (Pers.) D.A.Reid on GBIF, some clarification of these synonyms is needed to review this preliminary assessment.

The taxonomy of C. cuculatus is listed as doubtful on GBIF.

Chanterelle species to be assessed as part of the chanterelle comprehensive project.

The type specimen is described from near Estillac in France.

No georeferenced occurrence data is available on GBIF for C. culculatus, but there are two specimens listed under C. culculatus collected in Sweden in 1945 and Switzerland in 1947. Both specimens were originally named as Cantharellus cupulatus and GBIF has highlighted both as having a fuzzy taxon match with C. cuculatus. These specimens are therefore excluded from the known range of C. cuculatus in this assessment.
Extent of range is unknown.

Only known from type description.

Type descriptions of C. cuculatus and Merulius cucullatus both describe the species growing from the dead bark of willow trees in winter time.

No further information is available.

No known threats.

Confirmation of taxonomic status, population and distribution data and ecology required to better assess species.
