Like several North American puffballs, Lycoperdon umbrinum is usually shaped like an inverted pear (as the result of its sterile base) and is about the size of a golf ball or, at most, a tennis ball. It features a granular and spiny surface, but the spines when present are very short (1 mm long or shorter) and are soft and narrow, rather than cone-shaped and wide-based. The surface—especially on the top—is usually a shade of brown, and in most specimens the entire puffball becomes brown fairly early in development.

The platform allows users to upload photos or videos of plants, animals, and other organisms, which can then be identified by a community of other users. In addition, iNaturalist also has an automatic identification feature that uses computer vision to help identify species. |
