“The mushroom is 2 to 5 centimetres”
“The ‘skin’, or peridium, is composed of two separate layers: the outer layer (exoperidium), which is a golden tan to yellowish brown color, separates away from the inner basidiocarp, and splits into several rays that curve backward (recurve) to the base”
“Unlike some other members of the genus Geastrum (such as Geastrum fornicatum) the arms do not push the basidiocarp off the ground; rather, it lies flat.”
“The inner spore-bearing basidiocarp is 0.5 to 2 centimetres (0.20 to 0.79 in) broad, and has a central pore surrounded by a circular dull-brown apical disc”
" the disc is distinctly ridged or depressed"
“The inside of the interior sphere is white when young, but matures into a mass of brown, powdery spores mixed with thick-walled fibres known as capillitium.”

I think it suits.

Haven’t found saccatum up to now.
But no fruitbody, description and microscopical details – no correct ID. Many Geastrum species are very deceptive.

is really very difficult. They are small. And what about G. saccatum?

It’s my doubt too

They are in a private property, I took pictures from the wall… maybe tomorrow or at weekend I find some courage to jump the wall.

Geastrum fimbriatum or Geastrum triplex. The photo is a bit blurred and not close enough but I guess one of the two must be the correct one.
