There are many different species of Geastrum and I am only confident enough to go as far as genus

With that very distinctive cup (collar) formed below the endoperidium by the splitting in the exoperidium you are most probably very safe to go with G. triplex as there don't appear to be any others recorded in the literature that do this. It also has a 'fibrillose, peristome seated on a broad, depressed, silky, pallid zone which is usually outlined by an upraised margin' - C.A. Grgurinovic "Larger Fungi of South Australia". Cheryl's description was written in 1997. However these days social media may now be showing others like this, if so I'd be interested in hearing about them.

Please read the description provided by Heino at ANBH; this make it easier for the amateur person to understand especially when they do not have access to the books you mention!

Updated description: With that very distinctive cup (collar) formed below the spore sac, (endoperidium) which is the inner wall of a fungus comprised of several parts (or multi walled) as seen in Geastrum. The outer wall or 'star' (ray) sections (exoperidium) splitting just below the spore sac (endoperidium) gives this cup or collar-like structure. So you are most probably very safe to go with G. triplex as there don't appear to be any others recorded in the literature of Geastrum that do this in Australia. It also has a 'fibrillose (covered with silk-like fibres), peristome (an edging around a stoma which is a mouth from which spores are discharged) seated on a broad, depressed, silky, pallid (a whitish, pale shade) zone which is usually outlined by an upraised margin' - C.A. Grgurinovic "Larger Fungi of South Australia". Cheryl's description was written in 1997. However these days social media may now be showing others like this, if so I'd be interested in hearing about them.

Hope this is clearer and easier for you to understand Paul.
