Astraeus, commonly known as the "earthstar," belongs to a group of fungi that are notable for their unique star-shaped appearance. This fascinating fungus can be found in various parts of the world, including the Comunidad Valenciana.

The Astraeus genus is characterized by the following features:

• Appearance: When mature, the fruiting body of Astraeus opens up to reveal a star-like structure, which is where it gets its name. The outer layer splits into segments that spread apart, resembling a star.
• Color: The inner spore sac, which contains the reproductive spores, is typically darker than the outer layer, often appearing a shade of brown or dark gray.
• Habitat: Astraeus species are often found in sandy soils or areas with poor organic matter, frequently in association with coniferous or mixed forests. In the Comunidad Valenciana, these fungi can be part of the diverse mycological landscape, thriving in local ecosystems.
• Ecological Role: As a mycorrhizal fungus, Astraeus forms symbiotic relationships with roots of certain trees, contributing to nutrient exchange and overall forest health.

While not typically considered a culinary delicacy, the unique morphology of Astraeus makes it an intriguing subject for study and appreciation by fungi enthusiasts and naturalists visiting the Comunidad Valenciana.
