The spores are rounded, with warts, and have dimensions of 3.
It is also attached to its substrate all over the surface before it opens, so the young mushrooms and undersides of the arms of mature mushrooms are geastru, covered with dirt and other debris. Run Zhang 1 and Dr.
However, one study from Brazil found that the earthstar contained a lot of beta-glucan, which has antioxidant, anti-inflammatory, and cytotoxic properties. Like puffballs, spore discharge occurs primarily when raindrops hit the top of the sphere.

The related species Geastrum fimbriatum does not have an apical disc, and its pores are slightly smaller. Catalogue of Life CoL. Characteristics of Phylum Ascomycota.
At first a smooth, egg-shaped ball with a pointed beak, cm wide, attached to the substrate by a point at the base; with maturity the outer skin peeling back to form more or less triangular, buff colored, non-hygroscopic arms; spore case up to 2 cm wide, more or less round, smooth, brownish to purplish brown, with a small conical beak that is surrounded by circular ridge or depression often resulting in a pale area ; cm across when arms are opened; interior of spore case initially solid and white but soon powdery and medium brown.

The mushroom is found in forests throughout the world and is widely distributed and common in North America. Geastrum saccatum is the earthstar most commonly featured in field guides–probably because it is widely distributed and common.
A small, puffball-like structure rests in a shallow depression at the center of the arms. Geastrum fimbriatum is a similar mushroom; its beak is not surrounded by a marked ridge or depression, and its buttons are attached to the substrate over a large portion of the mushroom rather than at a basal point thus the buttons and, later, the undersides of the arms are usually covered with debris.
Initially, the fruiting body is geashrum in appearance to puffballs —and has strands of mycelia rhizomorphs at the base that attach it to the growing surface.

If you cut open the spherical part in a young specimen, the interior will be white and solid. The mushroom remains attached to the ground and the arms do not lift the mushroom up.
Small size cm across when arms expand ; A spore case that sits directly on the arms, as though in a bowl without a pedestal ; A hole in the spore case that is not prominently lined; A circular ridge or depression around the hole; Buttons that are only attached to the ground in one place and therefore do not accumulate much soil and debris.
Geastrum saccatum Scientific classification Kingdom: Presumably, this study was prompted by people either using the mushroom medicinally or having a geastfum to use the mushroom medicinally.
