Dicranella palustris (English spelling) Dicranellapalustris

...This does not refer to a specific species of moss, but is a general term for moss that has formed a spherical mass of many individuals due to various reasons. The Marigoke of Lake Inawashiro is famous, and is formed when the plant body of the moss Dicranella palustris (Dicks.) Crundw. ex Warb., which grows in colonies on the lake bottom, breaks off and rotates on the bottom due to the movement of the waves, gradually forming a spherical mass. Sometimes it grows in large numbers and is washed up on the shore.
