╔═ Morphology

not recorded

╔═ Ecology

Damp dead hardwood, especially beech and oak twigs and trunks

╔═ Foraging status
Species protectionNo species-specific restriction under federal law
Red List (Germany)* — Not threatened

⚠ Before you pickWild fungi may be taken in small quantities for your own use (§39(3) BNatSchG) — but not in nature reserves or national parks, on closed land or on farmland in use, and never for sale (§39(4)). In Bavaria this right is anchored in Art. 141(3) of the state constitution and is limited to locally customary amounts; the competent authority is the district nature-conservation authority (untere Naturschutzbehörde). Local signs and ordinances come first.

Species protection from BArtSchV Annex 1 and §2(1), retrieved 2026-10-15; Red List from Dämmrich et al. (2016) (BfN / Rote-Liste-Zentrum). Not legal advice — local rules and signage may be stricter. BArtSchV Annex 1 · Red List data

╔═ Edibility

not recorded

Inedible — too small and insignificant

  • ▸ Small, slender, whitish to pale beige pin- and cup-shaped fruit bodies only a few mm tall
  • ▸ Spore-bearing disc at the tip
  • ▸ Grows in clusters on bare, dead wood, often beech and oak
  • ▸ Inconspicuous and easy to overlook
╔═ Notes

A tiny ascomycete that only catches the eye when you deliberately search damp, lying hardwood.
