Hygrophanous

Hygrophanität refers to the ability of some fungi to change in case of loss or uptake of water color. Generally, this property is related to the mushroom cap. Since the dehydration usually vonstattengeht not uniform, the fungus often shows differently colored areas or flame-shaped, radial striation, depending on the degree of saturation by water. At the same time the humidity of the mushroom cap often leads to an increased transparency, especially in the marginal zone, which, for example, the blades emerge through the hat round. The Hygrophanität can be used as a recognition of fungal species.
