Astreus -

In mycology, Astraeus is a genus of "earthstar" fungi known for their hygroscopic nature—their outer layer opens like a star in wet weather and closes when dry to protect the spore sac.

These fungi form ectomycorrhizal (mutually beneficial) relationships with the roots of trees like the sal tree in Thailand or various shrubs.

He is often depicted in a starry cloak, presiding over the celestial majesty of the heavens. 2. Biological Science: The Astraeus Genus
