Appearance

As with all Agaricus species, gills are free, colour progresses with age from pale-pink to a chocolate color, and spores are dark brown. The stipe has a clear annulus (ring).

Cap 4-15 cm wide, and appears brownish due to numerous brownish scales on a white background. Stipe is white, 6-12 cm tall and 0,8-2 cm thick, cylindrical and wider towards the bottom, or ending in a bulb.

It is distinguished from similar forest-growing Agaricus mushrooms in that it does not bruise yellowish or reddish when cut and the widening stipe. Taste is mild and the mushroom is edible.

Habitat

Known to occur in Western and Southern Europe and New Zealand, this uncommon mushroom is found in deciduous or coniferous forest in autumn.
