Observation 7946: Geastrum saccatum Fr.

Some Earth Stars that I photographed before our Winter rains.
Looks like I got the naming incorrect. (Fancy that.) Have updated as Nathan also agrees with Deb.

Most Australian books, (Fuhrer, Syme, probably more that I don’t remember) have pictures of G. saccatum calling it G. triplex. I saw saccatum or something close to it in southeast QLD; and also what I think is G. velutinum

Why this species?

I happen to be studying the Geastrums because I found a couple myself. Geastrum triplex is usually shown with a of collar between the outer case and the spore case. I don’t see that on any of these. Perhaps these are Geastrum saccatum? They seem to have the halo around the apical pore.
