The colony is tubular with short branches that occasionally grow over and across each other. The body wall is soft, transparent and colorless, becoming slightly amber in older regions; a raphe along the zooids is occasionally faintly visible. The few available floatoblasts have small, well spaced tubercles on the fenestrae (

. The dorsal fenestra is relatively large, with a length and width only 20–25% smaller than the ventral fenestra. The sessoblast is larger than the floatoblast, measuring 550–570 μm in length. The sessoblast frontal valve bears numerous small tubercles, each about 2 μm in diameter and increasing in height towards the periphery to reach a length exceeding 4 μm. The annulus is clearly reticulated and has a distinctive thickened rim
