: sterile colony growing over varied debris fixed on a portion of fishing wire.
Remarks
. Hydrorhiza creeping, giving rise to short, smooth pedicels, each carrying a 520–730 µm long and 310–365 µm wide hydrotheca; margin slightly flaring, 360–400 µm wide at aperture. The cnidome comprises four
types
of capsules: 1) small, ovoid microbasic heteronemes,
ca
. 5.0×2.6 µm, of rare occurrence in the coenosarc; 2) fusiform microbasic mastigophores, (6.1–6.9)×2.1 µm, abundant in the tentacles and the coenosarc; 3) tubular microbasic mastigophores with a rather prominent, lateral "beak" at insertion of the shaft,
ca
. 6.6×2.1 µm, rarely occurring in the coenosarc; 4) large, elongate-ovoid microbasic heteronemes, (17.8–18.6)×(5.3–5.8) µm, abundant in the hydrorhiza.
