Incertae_sedis_

Hongo incertae sedis Hyphodontia sambuci sobre a rama de saúco.

The Latin term incertae sedis is used in taxonomy to point out the inability to locate exactly one taxon (eg a species or genus) within the classification. It is commonly abbreviated as inc. thirst. Its necessity reflects the bias of systematic knowledge, and behind its use there is most often a lack of agreement among specialists, not lack of information or hypotheses about kinship. Its use should be considered provisional and lasts as long as it takes to gather evidence of taxon relationships.

For example, the fungus, until now little studied, Hyphodontia sambuci that grows on the bark of the elderberry (Sambucus nigra) in the form of white spots, in 2006 was classified as a incertae sedis.
