Pigskin Poison Puffball

Pigskin Poison Puffball at Carderock

I found three of these at Carderock Park next to the Potomac River.
Carderock is on the border of Virginia and Maryland in Maryland.
I came here because I will go to Carderock for camp.

Description:Mushroom:2.5-10 cm wide 2-4 cm high,yellow brown color,spore mass whitish,soon becoming marbled and purplish-black to black.

Habitat:Single to many,on the ground,on wood debris,near trees,in woods and sandy soil.
Range:Widely distributed in North America.
Comments: Also known as S.aurantium. This mushroom is the most common species of Scleroderma. In parts of its range, it is sometimes parasitized by the Parasitic Bolete. It is often thought to be some kind of puffball-hence the common name-but its thick, rindlike skin and marbled,purplish-black spore mass distinguish it. Although sometimes used in place of truffles, it is known to cause nausea and vomiting.
