Answer:
Calvatia craniiformis
Explanation:
In writing scientific names, the genus nomenclature precedes the specie nomenclature and its first letter is usually written in capital. This is followed by the specie nomenclature that is denoted in small letters. Since these names are special or unique names, they are usually italicized to pinpoint that.
The scientific name Calvatia craniiformis is used for the fungus, brain puffball which is usually purple in color. It belongs to the family, Agaricaceae.
