Genus Ute Schmidt, 1862

TYPE SPECIES. — Ute glabra Schmidt, 1864 by monotypy.

DIAGNOSIS. — Grantiidae with a syconoid organization. The cortex is supported by giant longitudinal diactines, and the choanoskeleton is articulate, composed of several rows of triactines with occasional tetractines. There are no radial fascicles of diactines.

DESCRIPTION

Calcarea belonging to the genus Ute are among the most beautiful calcareous sponges. They have a regular tubular form with a vitreous, smooth and shiny surface due to many longitudinal, parallel diactines ( Fig. 19 ).

The relationship between the genera Ute and Aphroceras has been discussed previously (Borojevic 1966).
