Turbinellus

Turbinellus was circumscribed by Franklin Sumner Earle in 1909. Of the three species originally placed in the genus he remarked "They constitute a striking and well-marked genus which seems to have more in common with the club-shaped species of Craterellus than with the following genus where they have always been placed."^[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 flesh is thick and cork-like. The hymenium (the fertile surface where spores are produced) have an irregular texture with folds that are forked and reticulate.^[1]
