Diagnosis
Digitate, pedunculate, lamellate to caliculate, fistulose and low, compact or amorphous forms. Psammocinia species are characterised by their sand-armoured surface, that can be conulose, covered with rounded tubercles or pitted, and regular, reticular fibre skeleton. The distinction between primary and secondary fibres is not always clear as they are often of similar diameter (Fig. 2I). Primary fibres are usually cored and secondary fibres may be uncored to fully cored. Primary fibres may form fascicles (Fig. 2H), typically near the sponge surface, but can be obscured by heavy coring (Fig. 2G). Adjacent primary fibres may be connected by wide secondary fibre webs of spongin, which resemble stretched plastic. Consistency is firm. Sand and debris scattered throughout the mesohyl can render these sponges brittle, but when filaments are present in high densities, these sponges are tough to tear.
