Aleuria aurantia is a cosmopolitan ascocarp fungus found fruiting mainly in late summer and autumn. Aleuria aurantia resembles orange peel turned inside-out. It is the brightest of the most common cup fungi. It forms cups or irregular discs of various sizes, to 4cm tall. It grows on bare clay or disturbed soil, typically along trails, banks, and dirt roads.
It has a 3-10 cm broad sporocarp that forms irregular cups, split or unfolded on one side. The spores are 16-21 x 10-11 µm, hyaline (glassy appearance), elliptical with two oil drops, roughened in a reticulate pattern at maturity.
The cup-shaped fruiting body allows raindrops to splash spores out of the cup into the environment where they will generate a new organism. It appears late summer to late autumn.
