Material examined. Gongju Weir, 26 May 2015; Chongho Reservoir, 2 May 2016; Malli Reservoir, 3 June 2016; Chopyong Reservoir, 2 August 2016; Bongseon Reservoir, 11 October 2016.

Substratum. Wood.

Remarks. Chae et al. (2017) reported Pl. rugosa with only floatoblast without the colony. In this study, we obtained colonies which are light brown to dark brown in color including both long and short branches. The colony is firmly attached to the substratum, such as wood, but raised at their tips ( Fig. 9A ). The flostoblast is also shown here ( Fig. 9B- D ).

Distribution. Korea, Japan, Italy, North America, and New Zealand.
