2 strong folds at peripheral, followed in series
by 3 getting progressively + rapidly smaller.
These occupy less than half the distance between

Umbilicus wide open, can look down it to
the apex. Base flat, abrupt angle
at edge of umbilicus + 1 well defined

Vertical folds cross base + outer umbilicus
making prominent elevations on the sharp edge
where base + umbilicus meet.
Aperture like Solariella? [underlined] but base
of it flat.
