Scleroderma Aurantium Earthstar Fungus: Identify & Learn More

earthball mushroom



The plant known as Scleroderma aurantium is commonly referred to as the Pigskin Poison Puffball or Common Earthball in the USA. It is a type of fungus rather than a plant, and thus it does not have a wide variety of common names. It is typically referred to by its scientific name.


  • Kingdom: Fungi
  • Phylum: Basidiomycota
  • Class: Agaricomycetes
  • Order: Boletales
  • Family: Sclerodermataceae
  • Genus: Scleroderma
  • Species: Scleroderma aurantium


Scleroderma aurantium is a type of fungus, specifically a gasteroid fungus, which is known for its hard, thick peridium (outer layer) that resembles pigskin, hence the common name Pigskin Poison Puffball. It does not have significant ornamental or commercial value and is not considered invasive or problematic. It is, however, important in forest ecosystems for its role in decomposing organic matter.


The fruiting bodies of Scleroderma aurantium typically range from 2 to 10 centimeters in diameter.


As a fungus, Scleroderma aurantium does not have leaves.


Fungi do not produce flowers. Instead, they produce spores for reproduction, which are contained within the fruiting body.


The term “fruit” in fungi refers to the spore-bearing structure, which in the case of Scleroderma aurantium, is the puffball itself.


Scleroderma aurantium does not have a stem. Its fruiting body is typically sessile, meaning it sits directly on the substrate without a stalk.

Cultivation and Care

Scleroderma aurantium is not typically cultivated as it is a wild fungus and has little to no value in horticulture or agriculture.


This fungus is not planted; it naturally occurs in the environment.

Soil Preference

Scleroderma aurantium is often found in well-drained soils, in both deciduous and coniferous forests.


Being a wild fungus, Scleroderma aurantium does not have specific watering needs provided by humans.

Sun Requirements

It typically grows in shaded areas under the forest canopy.


Pruning does not apply to fungi.


Propagation of Scleroderma aurantium is through the natural release of spores from the mature fruiting body.

Health & Safety

Scleroderma aurantium is considered poisonous and should not be consumed by humans, dogs, or cats. It contains toxic compounds that can cause gastrointestinal distress and other symptoms if ingested. There are no thorns or spines, and it is not known to cause contact dermatitis.

Pests and Problems

As a fungus, Scleroderma aurantium does not typically suffer from pests in the way plants do. It is more affected by environmental factors such as competition for resources with other fungi and changes in habitat. However, like other fungi, it can be subject to fungal diseases and parasitism by other fungi or bacteria. Specific pests and problems are not well-documented due to its status as a wild organism with limited interaction with human cultivation.
