Western giant puffball : ウィキペディア英語版 | Western giant puffball
The western giant puffball (''Calvatia booniana'') is a puffball mushroom that can grow 10 to 70 centimetres (3.9 to 28 in) in diameter, as large as its close relative, the giant puffball of eastern North America and Europe. Like the giant puffball, it grows on composted soil such as in meadows, fields, and forests,, as well as on roadsides, sagebrush flats, pastures, and other sunny places.〔 In general, western giant puffballs occur on the west side of the Rockies and giant puffballs occur on the east side. However, on the West Coast of North America the western giant puffball is replaced by the giant puffball or a closely related species.〔 Its shape is round or a flattened sphere with no stalk, and it at least across when mature. The exterior is white or tan. Unlike giant puffballs, which are smooth, the western giant puffball is covered with plaques or large pointed warts. The interior is first firm and white, then yellow and slimy, and finally powdery.〔 ==Reproduction== Unlike most puffballs the western giant puffball reproduces in three stages asexually. Smaller western giant puffballs usually clump of the epididymal covering of the parent.
