Hygrophanity
Hygrophanity using the example of the blue bald head ( Psilocybe cyanescens )
Hygrophanity (from ancient Greek ὑγρός hygrós "moist, wet" and φαίνω phanos "seem, appear") describes the property of some mushrooms to change color when they lose or absorb water . Usually this property is related to the mushroom hat.
Since the dehydration does not usually take place uniformly, hygrophan fungi often show differently colored areas or flame-shaped, radial stripes, depending on the degree of saturation with water. At the same time, the moisture in the mushroom hat often leads to increased transparency , especially on the edge of the hat, which means that the lamellae can be seen through the hat, for example .
The hygrophanity can be used as a distinguishing feature of mushroom species.
