Brown Mottlegill - Panaeolina foenisecii

Alternative names
Lawnmower Mushroom and as The Haymaker

Cap 1 to 2 cm across, caps are initially bell-shaped or conical, expanding to become broadly convex; hygrophanous, medium to dark brown when moist, drying from the centre outwards to a creamy-beige. The hygrophanous nature of the cap means that colour is not a significant identifying feature; some caps may be dark brown while others, in drier parts of the same lawn, may be a pale creamy-beige even appearing white in bright sunlight. Spore print dark brown, spores 11-16 x 5-8µm with germ pore.
