LYCOPODINA COMATA ( LUNDBECK, 1905)

( FIG. 31; TABLE 5)

Original description: Asbestopluma comata Lundbeck, 1905: 72 .

Type material examined: Holotype: ZMUC-DEM-285, the Danish Ingolf Expedition, st. 78 (13 June 1896, 60°37ʹN, 029°52ʹW, 1504 m).

Diagnosis: Minute, pedunculate, cup-shaped greyish white Lycopodina with peduncle mycalostyles, body subtylostyles and smaller subtylostyles and thin, polytylote, tapering subtylostyles. Microscleres arcuate to palmate anisochelae c. 17–19 µm.

Description: The species is known only from the holotype and is a minute, pedunculate sponge with a cup-shaped body. Body 2 × 2 mm, laterally compressed, possibly during collection, and the upper margin folds slightly inwards. Peduncle approximately 8 mm tall and less than 100 µm wide. Basal part missing. Colour in ethanol light grey ( Fig. 31A).

Skeleton : Peduncle composed of tightly packed mycalostyles which gradually fan out in the upper part into the sponge body. Skeleton of the sponge body composed of subtylostyles, with the smaller category associated with the upper margin of the sponge. The polytylote tapering styles project from the sponge body ( Lundbeck, 1905).
