Nectria peziza

Species of fungus

Nectria peziza or yellow spot is an ascomycete fungus with bright yellow to orange globose fruiting bodies found on rotting polypores, well rotted deadwood, bark, dung, and decaying cloth. Its 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.
