Wavy white mushrooms

Gymnopus peronatus (syn. Collybia peronata) is commonly referred to as the Wood Woollyfoot, on account of the lower half of the stem being covered in fine white hairs. This widespread and common mushroom of leaf litter is poisonous; its cap colour is also very variable, which can make confident identification more difficult. Commonly known as the Wood Woollyfoot, this attractive little mushroom is sometimes recorded under the synonymous scientific names Marasmius peronatus or Marasmius urens.
