Turbinellus is a genus of five species of fungi in the family Gomphaceae.

"[1] The genus, along with several others in the Gomphaceae, was reorganized in the 2010s after molecular analysis revealed that the older morphology-based classification did not accurately represent phylogenetic relationships.

[2][3][4] The type species, Turbinellus floccosus, had been placed before then in the genus Gomphus.

[3] Fruit bodies of Turbinellus species are wrinkled, with a turbinate shape–like an inverted cone or funnel.

The hymenium (the fertile surface where spores are produced) have an irregular texture with folds that are forked and reticulate.
