Astraeus hygrometricus (Pers.:Pers.) Morgan |
The fruiting body is star-shaped with 6-15 rays, opening or closing depending on the humidity level, and with a central spore sac, with whitish grey to brown rays, the spore sac being light grey to beige, without stem. The fertile surface is internal: the spores are released as dust when mature. It grows on the ground, in dunes, woodlands, sandy soils, more often in warm climates, on a rather acid soil. The fruiting period takes place from August to December.
Astraeus hygrometricus is rare and confined in the forest of Rambouillet, and is quite rare, more generally speaking . | ||
