Crowded brown mushroom clusterI've seen in the park today a cluster of a hundred brown mushrooms. The grow in the grass, among very scattered oak, pine and birch.
The whole mushroom is matt brown (stem, gills, cap). The cap, shield shaped, has slighty darker concentric freckles.
The stem is 10 cm high, bulbous and without ring and without volva.
The cap 8 cm diameter.
Three days ago they weren't there (last time I passed by)
Any idea of what they may be?
