The only confirmed record of Cantharellus schmitzii appears to be the type specimen, collected from southern Democratic Republic of Congo. In the absence of any further data, it is not currently possible to accurately apply the Red List categories and criteria and the species could theoretically fall into any category. Therefore, it is assessed here as Data Deficient.

This species is known from the type collection at Kipopo, Haut-Katanga, Democratic Republic of Congo (Heinemann 1966), and there are no other known collections (Buyck et al. 2013).

The type collection noted that there was abundant material of this species (Heinemann 1966), so it is a surprise that this species has not been collected again since.

The genera Cantharellus consists of species forming ectomycorrhizal associations with trees. The collection of this species occurred in March, where it was collected in woodland, in humid soil at the base of a tree (Heinemann 1966, Buyck et al. 2013).

Without a clearer idea of the full distribution of the species it is not currently possible to accurately identify any specific threats to this species.

Further research to find further specimens, and to get a clearer idea of the ecology and the distribution of the species is needed.
