Naematelia aurantia

This orange, brain-like, gelatinous fungus, shiny when wet and dull when dry, parasitizes hairy curtain crust.

Appearance

  • Orange, gelatinous mass of convoluted folds with blunt margins, resembling a brain, about 2-10 cm. wide
  • Without a stipe (stem)
  • Shiny when wet, dull and stiff when dry
  • Grows scattered

ID Tips

  • May be confused with witch’s butter (Tremella mesenterica), which can only be distinguished microscopically, but if growing on hairy curtain crust (Stereum hirsutum), it is golden ear

About

  • Basidiomycetes – a major lineage of fungi that usually produce spores within basidia (club-like structures)
  • Found throughout our mushroom season
  • Parasitizes hairy curtain crust (Stereum hirsutum), which feeds on dead hardwood (e.g. oaks)
  • Edibility (San Mateo County Parks prohibits removal of any natural material)
    • Edible, but flavorless
    • Unless you are an expert, do not pick and consume wild mushrooms

Fun Facts

  • Golden ear belongs to a group of fungi known as jelly fungi, since many have gelatinous basidiocarps (fruit bodies) which are well adapted to periodic drying
    • About 20 species in this group have been reported in California
