The Schell helix is a long-lived, clonal column formed by a dense fungal matrix that hardens into wood-like matter. Colonies cluster in sandy shallows and rise as monumental cones.

Etymology

Schell and from English helix.

Morphology

A mature helix resembles both a tree and a fungus: a thick, spiraled trunk that tapers into a blunt crown. Its surface is mainly pale yellow or off-white. The outer skin alternates between smooth chalky layers and fibrous ridges. Rings of chambers and ledges punctuate the spiral. At maturity, the cones display ornate spore-pods that glisten with sticky, sweet gel.

Physiology

Hardens into wood-like matter.

Behavior

Life Cycle

Colonies grow slowly but persistently, adding less than a meter of height per year. Some giants surpass 30 meters.

Social Structure

Clonal columns cluster in sandy shallows.

Ecology

Their hollow chambers and ledges host nesting birds (like the helix finbird) and ground dwellers (like the marpichi). Helices expand by extending root-like cords underground, by rooting fragments broken off by storms, and by producing sexual spore-pods. The floral stage of the pods attracts animals with its nectar-like gel for spore dispersal.
