Comments: A. hygrometricus is easily recognized in the field by its hygroscopic rays. They open and close in response to humidity levels in environment; open when the humidity is high and closed when the humidity is low. This feature is very important for the mushroom because it can disperse the spores when the humidity is optimal and this ensures the conservation of the species.
