Clouded funnel - Clitocybe nebularis

"Clitocybe nebularis" or "Lepista nebularis", commonly known as the clouded agaric or cloud funnel, is an abundant gilled fungus which appears both in conifer-dominated forests and broad-leaved woodland in Europe and North America. Appearing in Britain from late summer to late autumn, it is edible but causes gastric upsets in many individuals.
