Nectria peziza or Yellow Spot is an ascomycete fungus with bright yellow to orange globose fruiting bodies (0.2 - 0.4 mm across) found on rotting polypores, well rotted deadwood, bark, dung, and decaying cloth. It's globular fruiting bodies (peritheca), quite large for the genus, may be isolated or crowded; they have a slightly prominent black dot at the top, the ostiolum, this being the entrance to the inner cavity; the bodies often collapse into a cup-shape when dry and the colour fades to pale yellow or whitish.
