I photographed this fungus on 15th August. It was growing beside a pathway at the edge of Wappenbury Wood in Warwickshire. Trees in the vicinity were mainly oak. There were 2 groups of the fungus, each with 2 or 3 growing. The larger of them had a cap with a diameter of about 10cms. The cap appears convex at first, but then seems to flatten and be umbonate. The centre – even in young specimens – is brown/rusty brown. The outer edge is white and seems striate. The gills are white and seem crowded. The stipe is comparatively broad and coloured white, although towards the base there is a hint of brown similar to the cap. The stipe does not have a ring. I hope the photos are sufficient to assist with identifying the species.
