Stalked Puffball (Tulostoma brumale) is one of a number of macro-fungi that occur on dunes. It’s quite small, about 2-3 cm high, with a small (pearl-sized) puffball head which is very pale in colour at this time of year. It produces a very neat, collared hole (ostiole) at the top through which the spores are released in typical puffball fashion. It occurs infrequently all along our coast in semi-fixed dune grassland, often growing in groups in bare sand. It’s most prominent in winter and early spring.
