ḆAEḝȓḇğffinjḍNj (ljḓ) Fredericella indica Annandale, 1909: 373-374 ; Wood and Okamura, 2005: 45, 76, fig. 13b; Hirose and

Mawatari, 2011b: 5-8, figs. 2, 3A.

Material examined. Susan reservoir, 5 Jun. 2015.

Substratum. Wood.

Description. Piptoblast broadly oval, long sides nearly straight and parallel with rounded ends, 204.50 μm long by 144.49 μm wide, length/width ratio of about 1.4 ( Fig. 2B). Surface extensively covered with prominent reticulation ( Fig. 2C).

Remarks. This species is reported from Korea for the first time. Colony was not found. We collected only one piptoblast in heaps at the edge of the reservoir ( Fig. 2A), which had an irregular, strong reticulum covering the surface. The surface of the piptoblast in the specimen seemed to be taken off when it was obtained in the substratum ( Fig. 2C). Fredericella indica is distinguished from F. sultana in having strongly reticulated piptoblast. Distribution. Cosmopolitan, including Korea and Japan.
