Common name: Porcelain Fungus/Poached Egg Fungus
Scientific name: Oudemansiella mucida
Introduction: The Porcelain Fungus (Oudemansiella mucida) is a UK-native fungus that is commonly found on beech wood. It can be both saprobic and weakly parasitic.
Cap: Semi-transparent and white, typically with a ‘wet-like’, shiny appearance. When first forming, they are usually convex, but they then tend to flatten with age.

Gills: Adnate and broad. When first forming they are typically transparent white, and as they mature, this white can then develop a brownish tinge to it.

Stem: Relatively slender with a large stem ring. Above the stem ring, the stem is typically white. Below the ring, the stem is typically more striate and has a greyish hue. They can also quite often be curved
Spores: Globose to sub-globose with thick walls. They have a white spore-print.
Forms in late summer to early autumn on dead trunks and fallen branches of beech trees. They can also occasionally form on dead upper branches of a beech too. When forming underneath a branch or fallen trunk, the stems of a Porcelain fungus adapts and curl around, making the caps lay horizontal.
Impact on Trees
The Porcelain fungus is weakly parasitic on the upper branches of living Beech trees. They are also saprobic on the dead stumps, trunks and branches of beech trees too.
The Porcelain fungus released a powerful ‘fungicide’ which help to get rid of competing fungi.
