Chara globularis var. hakonensis H. Kasaki

Hakone Stonewort (Chara globularis var. hakonensis)

The Hakone Stonewort was described in 1965, originally as a full species, this freshwater alga was endemic to Lake Ashi, also known as Ashi-no-ko, a crater lake in the Hakone area of the Kanagawa Prefecture on the island of Honshu, Japan.

This alga apparently disappeared due to water pollution which lead to a decrease of sunlight, which again lead to the dieback of the algae meadows.

The species was apparently locally known as Hakone-syazikumo.
