My stars have been dehydrated and bagged. The long beaks and the white halo, in addition to those three layers, look to be good macro characters.

I love finding these stars, too, no matter their names!

Just got my copy of “Mushrooms of the Southeastern US,” and saw photos of an incredible star w/out a stomach: Chorioactis geaster. Can’t wait to find one of these upon my next trip to the SE! ;)

Your on a slippery slope by saving a collection of Geastrum. Ten years from how you will have hundreds of collections and you will be seeing stars.
Your first collection is worthy of a first, you have all stages of development. When you save Geastrum they need to be dehydrated, which helps with the ID.
There are other Geastrum with long beaks but this feature does help. The mouth of G. triplex is raised and uneven with a white halo around it. Also the fleshy layer usually breaks up in a manner that forms a bole around the inner peridium.

that prominant beak on the young material is a give-away, I guess…

unless other, similar Geastrums also have one? I also have the fruit bodies here.
Too cool to leave behind!

Any micro features that nail the ID?

nice. it’s a first find of G. triplex for me.

Good question.

In some cases you can take away what it is not and end up with what it is.

Most of the time it is not that easy and more work is needed.

All of the time they are just pretty and a joy to work with.

How do you know?

How do you know it is G. fimbriatum? How can you tell by sight? :-) thanks! SJ
