Earthstar development (Astraeus hygrometricus)

In the Earthstar shots I have posted, some members where interested in how did this strange fungus grow, as all my posts, show "full developed" fruiting bodies.

So I looked for a shot which shows the whole process:

First, only a emerging ball can be seen, making its way out of the moss (the one on the left)

Then, the "skin" begins to open curving downwards (the one on the right)

The skin reaches the ground, lifting the spore sac up (both on the middle, the darker is the oldest).
In this point, the conection to the ground brakes and the whole on the top opens, becoming an independant sporing device.

It is usual to fing them far from the growing place. Like in this case, when they grow on a vertical wall, sometimes they fall down, and you can find several in the wall edge.
Also the wind, water or contact with animals, move them around, and they last for almost a year... this is a good design, isn´t it?

If you want to see a good detail, this is the same specie I posted in a large post HERE.

Hope you like!

Felipe, what funny characters they look! And they're growing up a wall too. Amazing find, and they can last for a whole year.
Felipe, I find this quite an amazing plant and I thank you for showing it and also your instructive notes as well.
You have captured them real well, it's a good natural shot with the 3 stages of growth showing. Yes, I do like it, thank you.

What an interesting and useful submission! The photo is technically excellent and as an illustration of the developing fungus I can't think of any way it could be improved. Well done! Earth stars either do not grow in my part of the world or they are rare enough that I have never found one.

Excellent work again from you Felipe, This has sharp detail, great DOF with perfect light and colors..Interesting shot with the multiple stages of development seen..Very well done!

Thank you for an excellent capture, photo, and note, in this wonderful and interesting composition, Felipe!


Hello Felipe,
this is an great Fungi Picture too. I know this kind, it looks funny. Great Shot with wonderful sharp background.

Martina :-)

Hi Felipe!
This is dream photo! I heard that these fungi grow in Poland, but never saw it. And you posted not one but all bunch of them ;-) Very educative - different stages and ages. Green moss is very suitable for composition. Quality is very high and note informative. Good work!

A new way of writing critiques. I hope you don't mind.


Scale 1-5, 5 is the best.

I like the frame a lot.


Great work as usual Felipe. Nice composition and DOF. I like the warm tones and the note.

I find this post with the different stages quite interesting. Its an unusual composition but the diagonal works and it creates the effect of them hanging down. I do find myself tilting my head slightly to the left when I view it though. You might have considered removing the dead leaf at the top left but I am nitpicking now. :)

Hi Felipe,
your taxonomic identification is correct but its right name is Astraeus hygrometricus (Persoon 1801) Morgan 1889, not Geastrum.
It si unmistakable because is the only specie (in Europe) with rays flattening to the substrate only with humid climate (inde nomen).
