A "hard-skinned puffball" is a type of mushroom that is characterized by its tough exterior and soft, spongy interior. It is commonly referred to as a "stony puffball" due to its hard texture, or a "leather-stalked puffball" because of the presence of a tough stem. Other synonyms for this mushroom include "horned puffball," "club-shaped puffball," and "thick-skinned puffball." Despite its firm texture, the hard-skinned puffball is a culinary delicacy and can be added to a variety of dishes. It is important to note, however, that not all puffballs are safe for consumption, so it is recommended to seek the advice of an expert before consuming any wild mushrooms.
