Jura. What are these large tufts of grass with strange tufts that border Lake Lamoura?

They flourish in the lake's valley and all spring long sport a small green tuft of hair on the top of their hump. Not animals, nor a separate plant species, what are these mounds with their unusual fringes called?
Arlette Dolne has taken to photographing these large, unusual clumps as she goes for walks and through the seasons. This resident of the Pays de Gex and "nature lover" "often goes up to the Haut-Jura to recharge her batteries, walk, and take photos." She regularly posts her photos on social media. One of them caught the attention of Internet users a few days ago and has racked up several hundred views.
There we can see several tussocks - and yes, that is their name - growing comfortably in the peat bog of the valley of Lake Lamoura , a Ramsar-certified wetland.
Contrary to appearances, the turadon is not in fact a plant, or more precisely, it is not a single plant. It is in fact a group of grasses, often of the Molinia species, which form large clumps. These herbaceous clumps are called turadon.
Particularly at home in wetlands, it's not uncommon to see certain peat bogs colonized. In winter, tussocks also roam the edges of lakes; they simply become more discreet and then take on the appearance of protuberances under the snow.
