Habitat & Geographic Range

Coastal wattle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 8 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (13 countries), Asia (Israel), Europe (4 countries), and North America (United States).

Common Glasscup

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Coastal wattle

Coastal wattle (Acacia cyclops) is a dense, fast-growing shrub in the family Fabaceae, native to the southwestern and southern coastal regions of Western Australia, from Shark Bay south to the Nullarbor Plain. It grows on coastal dunes, sandy scrubland, and limestone substrates near the sea, where it tolerates salt spray, wind, and summer drought. Coastal wattle produces distinctive circular seeds with bright red arillate coatings, making them highly attractive to birds. Although valued in its native range for coastal stabilisation and revegetation, the species has become highly invasive in southern Africa, particularly South Africa, where it was introduced for dune stabilisation in the 19th century and has since spread extensively across the Cape Floristic Region, displacing native fynbos vegetation. It is listed among the 100 worst invasive species globally by the IUCN Invasive Species Specialist Group. In Australia, it is assessed as Least Concern. Management of invasive populations in South Africa involves mechanical removal and biological control efforts aimed at protecting the critically threatened fynbos biome.

Common Glasscup

<em>Orbilia xanthostigma</em>, commonly known as the common glasscup, is a saprotrophic fungus in the family Orbiliaceae. The species has been documented in Belgium, Denmark, Norway, and Sweden, and is understood to have a broader distribution across temperate Europe. Fungi in the genus <em>Orbilia</em> are characterized by their small, typically pale or brightly colored, cup-shaped to disc-shaped fruiting bodies (apothecia) that form on decaying wood and plant matter. <em>Orbilia xanthostigma</em> typically grows on the surface of dead and decaying wood, including logs and fallen branches in forest and woodland habitats. The species is not currently evaluated for conservation status. As a saprotrophic organism, the common glasscup contributes to decomposition processes and nutrient cycling in forest ecosystems by breaking down woody substrates. Biological traits of this species remain poorly documented in the scientific literature. The genus <em>Orbilia</em> is also notable within mycology for including species that are predatory on nematodes, though the dietary habits of <em>O. xanthostigma</em> specifically require further research.
