Taksoni kirjeldused

Nestor, V., 2005

Diagnosis. Vesicle conical, with concave or convex base and broadly to bluntly rounded basal margin. The vesicle flanks are slightly convex, tapering towards the aperture, where a thin-walled collerette occurs. The neck is not distinguished from the chamber, neither shoulder nor flexure is present. The central part of the base carries a wide conical mucron, formed by a thin membrane or wall. The vesicle wall has dense fine rugose or granular ornamentation, somewhat coarser at the base.
