The Common Weather Star ( Astraeus hygrometricus ) is a fungal art from the family of Sclerodermataceae . Sometimes it is placed in its own order Sclerodermatales together with the Hartbovists and pea sprinklers.
features
The exopperidia of the common weather star, which is dark brown inside and later tears into lumps, consists of 5–12 lobes that are 3.5–8 cm wide when open and 1.3–2.5 cm wide when rolled up. The spherical endoperidia is about 12.5 cm wide, beige to gray-brown and sessile. The common weather star got its name because of its pronounced hygroscopicity: When dry, the lobes of the exoperidia close again over the endoperidia. This behavior is also shown by some of the earth stars, which are not closely related to the weather star . The fruiting bodies appear from August and persist until the following summer.
ecology
The common weather star is a mycorrhizal fungus . which can be associated with various deciduous and coniferous trees. It grows in acidic deciduous and coniferous forests, especially in dry, sandy places, often on south or west slopes. The species occurs almost worldwide, with the exception of the boreal, alpine and arctic regions. The northern distribution in Europe extends to southern England , northern Germany and central Poland.
