Bovista pusilla
Fruiting body: subglobose, (5–) 9–15 (–20) mm in diameter. Exoperidium: initially white, smooth to finely warted or tufted. In mature specimens the exoperidium disappears in the lower portion of the fruiting body but usually remains as a greyish-yellowish brown membrane or small granules in the upper part. Endoperidium: in mature specimens is usually exposed towards the base, dark brownish sometimes with slightly violet tinges. In old and weathered specimens, the endoperidium is fully exposed and dark brown. Peristome: Inconspicuous, flat to slightly protruding, not surrounded by a delimited peristome or a peristomal depression or fimbriate (fringed by hairs). Spores: subglobose to globose, 4.5-5.5μm in diameter, finely warted with a pedicel, 3-9μm long. Capillitium heteromorph. In centre of the gleba is of intermediate Bovista-Lycoperdon type with dichotomous branching and tapering ends; without septa. Outer parts of the gleba of Lycoperdon type with long, scarcely branched threads. Septa scattered to abundant.
Found on lime rich sand and sandy soil in sand dunes. In Europe it also occurs on cliffs and limestone pavements.
