| Specimen is a basal fragment of a tubular sponge with missing apical region. A central cavity is present, presumably opening with a single apical osculum, which is missing in the specimen. |
| beige-brown |
| Presumably a single apical osculum, which is missing in the fragmentary specimen. |
| Rough appearance due to the large tangential triactines |
| Reduced, small tetractines in the atrial wall and small v-shaped triactines with one ray almost completely reduced that occur scattered in the choanosome. Some large tetractines similar to the cortical ones appear to be very rarely present in the lower part of the choanosome. |
| Large tangential triactines and rare large tetractines with their apical ray reaching into the choanosome. |
| Cortical triactines (variable in size, Mean: 622.7 um (up to 954.2 um) x Mean: 25.5 (up to 30) um. Cortical tetractines up to 1126.2 um (max. apical: 1208.6 um). Small choanosomal tetractines 60.3 x 5.6 um, choanosomal V-shaped reduced triactines (31.3 x 3.2 um). |
