Spicules. Large tylostyles, 700-950 × 10-15 μm, medium tylostyles, 350- 560 × 10-15 μm and small tylostyles, 170-245 × 5-7 μm. Etymology. This species name, viridis, is named after the sponge green color in life. Remarks. This new species is similar to P. sasuensis, but differs in surface papillaes. This species has large tube-like papillae, but P. sasuensis has numerous small papillae. This species is similar to P. offinis Thiele in size of spicules, but differs in papillae shape. Polymastia offinis has conical shape of papillae, but papillae of this species are large tubercular shape.Published as part of Kim, Young A & Sim, Chung Ja, 2021, Ten new species of families Suberitidae and Polymastiidae (Demospongia: Heteroscleromorpha) from Korea, pp. 168-183 in Journal of Species Research 10 (2) on page 178, DOI: 10.12651/JSR.2021.10.2.168, http://zenodo.org/record/812001
