Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Collared Earthstar

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Belgium, Brazil, Norway, and United States. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

pigargo-americano

A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.

Collared Earthstar

<em>Geastrum triplex</em>, the Collared Earthstar, is a gasteroid fungus in the family Geastraceae, order Geastrales. This species is assessed as Near Threatened on the IUCN Red List, indicating that it may be at risk of qualifying for a threatened category in the near future. It has been recorded in Belgium, Brazil, Norway, and the United States, and is associated with forest floors, decomposing wood, and soil. Earthstars in the genus <em>Geastrum</em> are recognized by their distinctive star-shaped fruiting bodies, formed when the outer wall splits and folds back into ray-like segments to reveal an inner spore sac. <em>Geastrum triplex</em> is distinguished by the formation of a collar or cup-like structure around the base of the inner spore sac, which gives rise to its common name. Like other gasteroid fungi, it disperses spores through an apical pore in the spore sac. Population estimates and trend data are not available. Biological traits of this species remain poorly documented in the scientific literature. Its Near Threatened status may reflect sensitivity to habitat disturbance and forest management practices.
