Assessment Notes
The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/266014734/266020050
Justification
The species is only known from its description in 1942, based on a specimen found in 1924 at a single location in France. The species has not been found since, so it is not possible to estimate the population size and trends and it is assessed as Data Deficient (DD).Taxonomic notes
The type specimen for Cystogomphus humblotii was initially identified as Gomphidius tomentosus, but after revaluation was assigned to a new monotypic genus based on its morphological characteristics (Singer 1942). The type and only specimen for this genus may have since been lost (Miller Jr. 1971).Geographic range
Only known from its type location in France, in Bois de Vincennes, Paris, France (Humblot 1926).Population and Trends
The species is only known from it type specimen from 1924, and has not ben found since or in any other localities. There is not sufficient information to calculate the current population size and distribution.
