Z] Fig. 53 - Zygomycale angulosa (D. & M.)- Spicules of specimen Scale a: 50 [/.m, scale b: 20 [xm. The ectosomal skeleton is distinct, consisting of a very regular tangential reticulation of spiculo-fibres 20-40 \Lxn. thick, forming meshes 180-280 \mi wide. Tufts of single spicules arise from the nodes. The choanosomal skeleton consists of a very irregular reticulation, more or less dense, of plurispicular fibres up to 250 \xvs\ thick, with spicular tracts and many spicules scattered. Spongin is not apparent. Spicules: 1) Subtylostyles mostly slightly flexuous, measuring 250-300 X [xm. The base is narrower than the middle of the shaft,.
