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.
