Thericium vulgatum group

We unite here a group of medium sized to large species, with moderately slender to slender conical shells characterized by a mid-whorl angulation bearing prominent tubercles. Axial sculpture is generally weak on late teleoconch whorls. Phylogenetically, these species might be related to the extant Thericium vulgatum (Bruguière, 1792) . Thericium podhorcense ( Hilber, 1882) and Thericium subcostatum ( Bałuk, 1975) are only tentatively placed in this group due to their aberrant morphologies.
