One of the most distinctive fungi in its family, this earthstar-like species produces a spherical spore sac atop a star-shaped outer layer that splits open into ray-like segments upon maturity. What sets it apart from related genera is its perforated spore case, pierced by numerous small openings through which spores are released — a feature responsible for its common name. As with other Geastrales, it functions as a saprotroph, breaking down organic matter in soil and contributing to nutrient cycling in the substrates it occupies.

The species has an unusually broad but highly fragmented global distribution, with records spanning dozens of countries across Europe, the Americas, Africa, Asia, and Australia, including the Netherlands, Spain, Hungary, Argentina, Brazil, South Africa, Australia, and India. It occurs exclusively in terrestrial habitats, typically favoring calcareous or nutrient-rich soils in open woodlands, grasslands, and similar settings, though it is rarely encountered even within its known range.

Its Critically Endangered status stems from ongoing habitat loss and fragmentation, agricultural intensification, urbanization, and pollution, all of which degrade the specific soil conditions the species depends on. Climate change is an additional pressure, altering soil moisture and temperature regimes across its range. Because it appears in small, scattered populations, local disturbances can eliminate occurrences entirely.

Conservation efforts remain limited, largely consisting of site protection where populations are documented, incorporation into regional red lists, and inclusion in fungal conservation assessments that inform habitat management. Population trends are currently unknown due to the difficulty of monitoring such a widely dispersed and inconspicuous organism. Given continuing habitat pressures across its range, its long-term outlook remains precarious without more targeted survey and protection efforts.

Sandy soils in open grasslands, heathlands, and sparse woodlands, particularly in areas with well-drained, nutrient-poor substrates. This species typically occurs in semi-arid to temperate regions where it forms fruiting bodies in sandy or gravelly soils with specific moisture and pH requirements.
