Nectria peziza

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.[1][2] 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;[3] the bodies often collapse into a cup-shape when dry[1] and the colour fades to pale yellow or whitish.
