The holotype is a 14.5 cm tall and 23 cm wide colony. A 15 mm long stem, 6 mm in diameter, subdivide in two main branches, 4-5 mm diameter and arise from an irregular, 15 mm diameter holdfast (Figure 1A). The branches are about the same diameter at the bottom of the colony 3-4 mm producing thinner branchlets 2-3 mm diameter up to the ends. Branching is irregular, mostly dichotomous, branches and branchlets project at angles 45°-75°and separated up to 25 mm. They spread in one plane in a fan-like colony. The branchlets are straight or curved inwards, some are anastomosed. Unbranched terminal ends are about 2 mm in diameter and up to 40 mm long. The axis is amber. The calyces are shelf-like, 1-1.2

long, giving a spiny appearance to the colony. They are close together, or only a few millimetres apart, 0.5-1.5 mm, and not imbricate (Figure 1B). Some branches are devoid of polyps, probably eaten by worms. Polyps are on the upper side of the
|
||

|
||
calyces. The calyx size and spacing vary from the larger branches to the thinner, being larger and acute, and closer placed at the branchlets and shorter, and distant at the main branches and almost absent at the stem. The coenenchyme is thin, composed of whitish and translucent sclerites, mostly of various kinds of spindles (Figure 2
|
||
<normalizedToken originalValue="A–C">A-C</normalizedToken>
|
||
). The coenenchyme and the calycular sclerites are mostly leaf-like spindles, 0.25-0.93 mm long, and 0.09-0.20 mm wide and spindles, 0.40-0.60 mm long and 0.06-0.10 wide (Figure 3
|
||
<normalizedToken originalValue="A–C">A-C</normalizedToken>
|
||
). The axial sheath is composed of spindles, 0.25-0.45 mm long and 0.04-0.07 mm wide (Figure 3D). The anthocodial sclerites are translucent irregular warty rods, thin torches, irregular short spindles, 0.05-0.2 mm long, and 0.01-0.05 mm wide (Figures 2D, 3D). The colony is whitish to pale yellow (Figure 1
