Oudemansiella mucida, commonly known as the Willow Shield or Porcelain Fungus, is a saprophytic fungus that grows on dead wood, especially that of willow trees. It is characterized by its slimy, white cap and gelatinous coating, which gives it a porcelain-like appearance. While not considered toxic, its edibility is debated, and it is generally not recommended for consumption due to its slimy texture and potential for confusion with other species.
How to Identify
- Cap
- The cap is typically 2-8 cm in diameter, convex to flattened, and pure white to cream-colored. It is covered in a thick, slimy, gelatinous layer, giving it a glossy, porcelain-like appearance.
- Gills
- The gills are adnate to decurrent, widely spaced, and white to cream-colored. They are often covered in a gelatinous substance, similar to the cap.
- Stem
- The stem is 3-7 cm long and 0.5-1.5 cm thick, white, and slimy below the ring zone. Above the ring zone, the stem is dry and may have a slightly velvety texture.
- Flesh
- The flesh is thin, white, and has a mild, nondescript odor.
- Fruiting body
- The fruiting body is generally small to medium-sized, with a distinctive slimy cap and a preference for growing on dead willow wood.
- Habitat
- Found on decaying wood, especially willow, in damp woodlands and forests.
