Morphological description (show/hide)
| massive, globular | | unknown | | light to dark red | | uniporal, elevated margins | | Not compressible, smooth on top, very hispid on the sides. | | Sides of the sponges are very hispid (oxeas). | | Radial skeleton. Triaenes are disposed radially near the surface. Oxyasters can be found throughout the choanosome. | | Ectocortex of spherasters, endocortex of sterrasters. Cortex is 1mm thick. | | (min-average-max, N=30) (a) oxeas, length: 1625-4190-6000 µm, width: 10-40.6-65 µm. (b) orthotriaenes, rhabdome length more than 4050 µm; width: 20-59.8-100 µm; orthotriaene clad length: 240-694.8-1125 µm. (c) no anatriaenes were found. | | (min-average-max, N=30 ) (d) sterrasters, length: 97-106.9-120 µm, width: 88-94.5-104 µm. (e) spherasters, spiny, 8-14.3-17.5 µm in diameter. (f) oxyasters, smooth, 15-27.3-58 µm in diameter. |

| The color of this specimen (in ethanol) is not typical. It has probably been stained by the encrusting sponge Hexadella dedrtitifera growing on it. G. phlegraei is usually yellowish-whitish. |
