Lacrymaria velutina (= L. lacrymabunda)
Broadly convex, yellow-reddish cap surface radially streaked with yellow and brown tinges. Gills black with spores, with pale edges. Stem is 5 to 10cm tall; with a ring zone of pale fibres stained black by falling spores. Grows in clusters.
Seen close to the path through small woods in a protected wetland area; path connecting two bigger ponds. This protected marsh (Etournel) is in Geneva lake valley.
If my identification is correct, this mushroom is edible when young, needs to be cooked quickly after harvest, and is of medium quality.
