Fungus
Steppe Earthstar
Geastrum striatumAlso known as Striate Earthstar, Striated Earthstar
Steppe earthstars unfurl star-like rays on dry, sandy soils to elevate a delicate central spore pouch above the ground. Raindrops striking the papery pouch force puffs of brownish spores out through a distinctive grooved, conical beak at the apex. Persistent rays often weather and harden, allowing these tough fruiting bodies to remain visible for months after releasing their spores.

Interaction riskLow

- Very high
- Why interaction risk is low
- Many wild fungi have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Identification: Examine the striate beak and collar ring where the stem meets the spore sac.
- Respect Habitat: Tread carefully in fragile dune and steppe environments where these grow.
