Hymeniacidon fusiformis sp. nov. Figures 18 & 20 Material examined. Holotype: CASIZ236657 / IZC00048452, Inner Carmel Pinnacle, (36.55852, -121.96820), 10–24 m, 9/22/21. Etymology. Named for its slightly fusiform styles. Morphology. Growing as an irregular mass, thickly encrusting with many projecting fingers and lobes, heavily fouled by hydroids and other animals. Sampled portion is 1 cm thick, but sponge was thicker in life. Firm and barely compressible; oscules and pores not evident. Skeleton. Choanosome a chaotic halichondrid reticulation with vague multispicular tracts meandering towards the surface. Spicule density high; spongin not apparent. Ectosome a dense mat of tangential styles approximately 200 μm thick, unstructured in some regions, and patterned into a semi-regular mesh in other regions. Large subectosomal spaces present, bridged by spicule tracts to support ectosome. Spicules. Styles: most are very slightly fusiform, so that they are thicker in the center than near the head of style. ... : Published as part of Turner, Thomas L. & Lonhart, Steve I., 2023, The Sponges of the Carmel Pinnacles Marine Protected Area, pp. 151-194 in Zootaxa 5318 (2) on pages 181-182, DOI: 10.11646/zootaxa.5318.2.1, http://zenodo.org/record/8162357 ...
