Crowned Earthstar is first of all a dunal coast earthstar.
That means this earthstar is in urban area dependant on sand supplemetion
from the Northsea or the former Zuiderzee, but there is also a dependance of typical trees and shrubs for the right soil conditions
Inside the urban district habitats are restricted to road-sides, harbors, railway stations and so on.
There are places enough that meet this conditions. Still the number of observations is small.
And that might be caused by the growing season: in late autumn and mid winter few people are hunting for earthstars in the urban area.

How to exclude mistakability:
- Describe the mouth-zone (growing-phase dependant)
- Is a stem visible (growing-phase dependant)
- Look at the bottom of the earthstar:
- Is it fixed in the ground (encrusted debris)?
- Is there a scar in the middel at the bottom of the star-rays?
- Is color changing at injuring
- If this is not helpful: dry the earthstar, and see what changes during the dry-process: stem, apophyse, collar, mouth-zone?
at the bottom of a vegetation poor slope
After breaking out debris,
and cleaning with water

Mistakability young, in moisty circumstances with:
- (Robust) Curling Earthstar (Geastrum pseudolimbatum)
- Tiny Earthstar (Geastrum minimum)
